Strike a Yoga Pose: Scissor Legs Side Crow to One-Legged Arm Balance

FitSugar — Mon, 02 Mar 2009 08:00:00 -0800

I've shown you all some pretty advanced arm balancing poses found in yoga; one being Scissor Legs Side Crow, a balancing spinal twisting pose where your legs are scissored out to the side. In another arm balance, One-Legged Arm Balance, you balance on your hands while your legs are in a split position. After experimenting with both poses, it's really fun to work on switching from one to the other without letting your feet touch the floor. It's a challenge but well worth the work.

To see how to do it, watch this video after you read more.

Music: "Infusion" by Adham Shaikh

Begin by getting into Straight Legs Side Crow, with your outer left thigh resting on your right elbow. Then bring your right leg behind you, scissoring your legs, coming into Scissor Legs Side Crow. Hold for a second or two.
Then bring your right leg forward and slide it in front of your left leg so your inner right thigh is now resting on your right elbow. Slide your left leg off your right elbow and bring it behind you. Your legs are now in a split, and you're in One-Legged Arm Balance pose. Hold for a second or two.
When you're ready, step your right leg back, coming into Four-Limbed Staff pose. Inhale to Upward Facing Dog, and exhale to Downward Facing Dog. Now try this sequence on the other side.

Also Called: One-Legged Arm Balance

Once you can do the prep, then you can work on the steps to get into One-Legged Arm Balance. With a little practice and determination, you'll be balancing in no time. To see the steps read more

From Warrior 1 with your right foot forward, lower your hands down to the ground and pick your back heel up. Bring your right shoulder as far underneath your right knee as possible, and plant your right hand next to the outside edge of your right foot.
Now rest the weight of your right hamstring on your right tricep and see if you can pick your right foot off the ground. Work on straightening the leg as much as you can (I know it's hard).
From here, lower your torso so that your left elbow presses into your belly between your ribs and your hip. This is the most important step.
Once your left elbow is into your belly and your right tricep is holding your right leg, press into your hands, lean your weight forward, and lift your left foot off the ground so you're balancing on both hands equally. Stay here for five or more breaths (or as long as you can) and then lower your feet down to the ground. Step your right foot back and take a vinyasa (Chaturunga, Up Dog, Down Dog). Then step your left foot forward, rise into Warrior 1 and try these steps on the left side.

Highlights

Diagnosing Scoliosis

Scoliosis is diagnosed typically in children 10 - 15 years of age. However, only about 1% of cases actually require treatment. There is a large female preponderance for larger curves that do require treatment.

Defining Scoliosis

Nonstructural scoliosis is a simple side-to-side curve of the spine. Structural scoliosis adds to that simple curve a rotation of the vertebrae, resulting in a twisting of the spine.

Causes

In about 80% of scoliosis cases, the cause is unknown (idiopathic scoliosis). Research has not been able to identify any genetic abnormality that would make a person susceptible to developing scoliosis.

Treatment with Bracing

Bracing has long been the standard treatment to prevent progression of the curvature of scoliosis. However, patient compliance has been a problem, especially for younger patients. Newer braces are now more comfortable and can be worn discretely under the clothing, thus improving patient compliance and treatment results.

Introduction

Scoliosis is the abnormal curvature of the spine. While the normal spine has gentle natural curves that round the shoulders and make the lower back curve inward, scoliosis typically involves a three-dimensional deformity of the spinal column and rib cage. To varying degrees, the spine curves from side-to-side, and some of the spinal bones may rotate slightly, making the hips or shoulders appear uneven. It may develop in the following way:

As a single primary side-to-side curve (resembling the letter C), or
As two curves (a primary curve along with a compensating secondary curve that forms an S shape).

Scoliosis most commonly develops in the area between the upper back (the thoracic area) and lower back (lumbar area). It may also occur only in the upper or lower back. The doctor attempts to define scoliosis by the following characteristics:

The shape of the curve
Its location
Its direction
Its magnitude
Its causes, if possible

The severity of scoliosis is determined by the extent of the spinal curvature and the angle of the trunk rotation (ATR) and is usually measured in degrees. Curves of less than 20 degrees are considered mild and account for 80% of scoliosis cases. Curves that progress beyond 20% require medical attention. Such attention, however, usually involves periodic monitoring to make sure the condition is not becoming worse.

Scoliosis affects about 2 - 3% of the population (about 6 million people in the United States). It can occur in adults but is more commonly diagnosed for the first time in children aged 10 - 15 years. About 10% of the adolescent population has some degree of scoliosis, but less than 1% develops scoliosis that requires treatment. The condition also tends to run in families. Among persons with relatives that have scoliosis, about 20% develop the condition.

Among adults, previous reports have indicated a prevalence of scoliosis of up to 32%. But a recent study of 75 healthy adults aged 60 years and older with no known history of scoliosis or prior spine surgery suggested a rate of 68%. However, scoliosis was not linked to physical or social impairment in this population.

Scoliosis is often categorized by the shape of the curve, usually as either structural or nonstructural.

Structural scoliosis. In addition to the spine curving from side to side, the vertebrae rotate, twisting the spine. As it twists, one side of the rib cage is pushed outward so that the spaces between the ribs widen and the shoulder blade protrudes (producing the rib-cage deformity, or hump). The other half of the rib cage is twisted inward, compressing the ribs.
Nonstructural scoliosis. The curve does not twist but is a simple side-to-side curve.

Other abnormalities of the spine that may occur alone or in combination with scoliosis include hyperkyphosis (an abnormal exaggeration in the backward rounding of the upper spine) and hyperlordosis (an exaggerated forward curving of the lower spine, also called swayback).

Click the icon to see an image of kyphosis.

The location of a structural curve is defined by the location of the apical vertebra. This is bone at the highest point (the apex) in the spinal hump. This particular vertebra also undergoes the most severe rotation during the disease process.

The direction of the curve in structural scoliosis is determined by whether the convex (rounded) side of the curve bends to the right or left. For example, a doctor will diagnose a patient as having right thoracic scoliosis if the apical vertebra is in the thoracic (upper back) region of the spine, and the curve bends to the right.

The magnitude of the curve is determined by taking measurements of the length and angle of the curve on an x-ray view.

Vertebrae. The spine is a column of small bones, or vertebrae, that support the entire upper body. The column is grouped into three sections of vertebrae:

Cervical (C) vertebrae are the 7 spinal bones that support the neck.
Thoracic (T) vertebrae are the 12 spinal bones that connect to the rib cage.
Lumbar (L) vertebrae are the 5 lowest and largest bones of the spinal column. Most of the body's weight and stress falls on the lumbar vertebrae.

Each vertebra can be designated by using a letter and number; the letter reflects the region (C=cervical, T=thoracic, and L=lumbar), and the number signifies its location within that region. For example, C4 is the fourth bone down in the cervical region, and T8 is the eighth thoracic vertebra.

Below the lumbar region is the sacrum, a shield-shaped bony structure that connects with the pelvis at the sacroiliac joints. At the end of the sacrum are 2 - 4 tiny, partially fused vertebrae known as the coccyx or "tail bone."

The Spinal Column and its Curves. Altogether, the vertebrae form the spinal column. In the upper trunk the column normally has a gentle outward curve (kyphosis) while the lower back has a reverse inward curve (lordosis).

The Disks. Vertebrae in the spinal column are separated from each other by small cushions of cartilage known as intervertebral disks. Inside each disk is a jelly-like substance called the nucleus pulposus, which is surrounded by a tough, fibrous ring called the annulus fibrosis. The disk is 80% water. This structure makes the disk both elastic and strong. The disks have no blood supply of their own, relying instead on nearby blood vessels to keep them nourished.

Processes. Each vertebra in the spine has a number of bony projections, known as processes. The spinal and transverse processes attach to the muscles in the back and act like little levers, allowing the spine to twist or bend. The particular processes form the joints between the vertebrae themselves, meeting together and interlocking at the zygapophysial joints (more commonly known as facet or z joints).

Spinal Canal. Each vertebra and its processes surround and protect an arch-shaped central opening. These arches, aligned to run down the spine, form the spinal canal, which encloses the spinal cord, the central trunk of nerves that connects the brain with the rest of the body.

Causes

In 80% of patients, the cause of scoliosis is unknown. Such cases are called idiopathic scoliosis. (Idiopathic means without a known cause.) Idiopathic scoliosis may be due to multiple, poorly understood inherited factors, most likely from the mother's side. However, the severity often varies widely among family members who have the condition, suggesting that other factors must be present.

Researchers have not been able to identify the specific genetic abnormalities that make a young person susceptible to spinal distortion. Inherited physical abnormalities, problems in coordination, abnormalities in the central nervous system, and other inherited factors may play some role either alone or in combination with other conditions to produce scoliosis.

Physical Abnormalities. Researchers are investigating possible physical abnormalities that may cause imbalances in bones or muscles that would lead to scoliosis. Among them are the following:

Imbalances in Muscles around the Vertebrae. Some research suggests that imbalances in the muscles around the vertebrae may make children susceptible to spinal distortions as they grow.
High Arches. One study showed a higher incidence of abnormally high arches in the feet in people with idiopathic scoliosis, suggesting that altered balance may be a factor in certain cases.

Problems in Coordination. Some experts are looking at inherited defects in perception or coordination that may cause asymmetrical growth in the spine of some children with scoliosis.

Genetic Abnormalities in the Central Nervous System. Genetic defects that cause altered processing in the brain may play a role in producing abnormalities in the growing spine. For example, research has implicated low levels of melatonin, a hormone secreted in the pineal gland in brain. Melatonin is involved with sleep and growth. Researchers speculate that genetic factors that cause reduced blood levels of melatonin may adversely affect muscle tone and development during sleep, perhaps contributing to scoliosis.

Other Biologic Factors. Several other biologic factors are being investigated for some contribution to scoliosis:

Abnormalities in collagen, the critical structural protein found in muscles and bones. Enzymes known as matrix metalloproteinases are involved in the repair and remodeling of collagen. Researchers have found high levels of the enzymes in the disks of patients with scoliosis, which suggests that the enzymes may contribute to curve progression. Elevated levels of the enzymes can cause abnormalities in components in the spinal disks, contributing to disk degeneration.
A possible defective gene responsible for production of fibrillin, an important component of connective tissue, which makes up bones and muscles.
Abnormalities in a protein called platelet calmodulin that binds to calcium. This protein acts like a tiny muscle and pulls clots together. Measuring levels of this protein may eventually help predict whether scoliosis will worsen.

Congenital scoliosis is caused by inborn spinal deformities that may result in the development of absent or fused vertebrae. Kidney problems, particularly having only one kidney, often coincide with congenital scoliosis. The condition usually becomes evident at either age 2 or between ages 8 and 13 as the spine begins to grow more quickly, putting additional stress on the abnormal vertebrae. It is essential to diagnose and monitor such curvatures as early as possible, since they can progress quickly. Early surgical treatment -- before age 5 -- may be important in many of these patients to prevent serious complications.

Adult scoliosis has two primary causes:

Progression of childhood scoliosis.
Degenerative lumbar scoliosis. Degenerative lumbar scoliosis is a condition that typically develops after age 50. With this condition, the lower spine is affected, usually due to disk degeneration. Osteoporosis, a serious problem in many older adults, is not a risk factor for new-onset scoliosis, but it can be a contributing factor. In most cases, however, it is not known why scoliosis occurs in adults.

Scoliosis may be a result of various conditions that affect bones and muscles associated with the spinal column. They include the following:

Muscle paralysis.
Muscle deterioration from diseases such as muscular dystrophy, polio, or cerebral palsy.
Injury to the spinal cord.
Tumors, growths, or other small abnormalities on the spinal column. For example, syringomyelia, a disorder in which cysts form along the spine, can cause scoliosis. These spinal abnormalities may play a larger role in causing some cases of scoliosis than previously thought.
Familial dysautonomia, a rare disorder in Jewish children of Ashkenazi descent. (Only about 500 cases have been reported.)
Stress fractures and hormonal abnormalities that affect bone growth in young, competitive athletes.
Birth defects, including spina bifida (an open spinal cord) and myelomeningocele (a hernia of the central nervous system).
Turner syndrome, a genetic disease in females that affects physical and reproductive development.
Other diseases that can cause scoliosis are Marfan syndrome, Aicardi syndrome, Friedreich ataxia, Albers-Schonberg disease, rheumatoid arthritis, Cushing syndrome, and osteogenesis imperfecta.

Spina bifida is a congenital disorder (birth defect) in which the backbone and spinal canal do not close before birth. In severe cases, this can result in the spinal cord and its covering membranes protruding out of an affected infant's back. Spina bifida may also be nearly inconsequential, or may be repairable through surgery.

Nonstructural scoliosis is usually not a serious problem, since the curve is side to side. It can develop from a number of physical problems, including the following:

Unequal leg length. Injury, a shortened Achilles tendon, or other structural in-born problems can cause this very common condition. Unequal leg length rarely causes any problems and in most cases requires no treatment other than a lift in one of the shoes to equalize the length.
Muscle spasms.

Risk Factors

Risk Factors for Initial Scoliosis. Idiopathic scoliosis, the most common form, occurs most often during the growth spurt right before and during adolescence. (Between 12 - 21% of idiopathic cases occur in children ages 3 - 10 years, and less than 1% in infants.) Mild curvature (under 20 degrees) occurs about equally in girls and boys, but curve progression is 10 times more likely to occur in girls. Being taller than average at earlier ages may put some girls at risk, but other factors must be present to produce scoliosis. A risk factor that affects females is a delayed onset of menstruation, which can prolong the growth spurt period, thus increasing the possibility for the development of scoliosis.

Risk Factors for Curvature Progression. Once scoliosis is diagnosed, it is very difficult to predict who is at highest risk for curve progression. About 2 - 4% of all adolescents develop curvature of 10 degrees or more, but only about 0.3 - 0.5% of teenagers have curves greater than 20 degrees, which requires some medical attention.

People with certain medical conditions that affect the joints and muscles are at higher risk for scoliosis. These conditions include rheumatoid arthritis, muscular dystrophy, polio, and cerebral palsy. Children who receive organ transplants (kidney, liver, heart) are also at increased risk.

In one study, idiopathic scoliosis occurred in about 5% of close family members of children with the condition.

Scoliosis may be evident in young athletes, with a prevalence of 2 - 24%. The highest rates are observed among dancers, gymnasts, and swimmers. The scoliosis may have been due in part to loosening of the joints, delay in puberty onset (which can lead to weakened bones), and stresses on the growing spine. There have also been other isolated reports of a higher risk for scoliosis in young athletes who engage vigorously in sports that put an uneven load on the spine. These include figure skating, dance, tennis, skiing, and javelin throwing, among other sports. In most cases, the scoliosis is minor, and everyday sports do not lead to scoliosis. Exercise has many benefits for people both young and old and may even help patients with scoliosis.

Prognosis

In general, the severity of the scoliosis depends on the degree of the curvature and whether it threatens vital organs, specifically the lungs and heart.

Mild Scoliosis (less than 20 degrees). Mild scoliosis is not serious and requires no treatment other than monitoring.
Moderate Scoliosis (between 25 and 70 degrees). It is still not clear whether untreated moderate scoliosis causes significant health problems later on. Some studies have found no difference in either back pain or survival rates in adult untreated patients versus the general population. In one study, adults with moderate scoliosis had normal lung function, although they had difficulty exercising. (This low exercise tolerance might have been because many patients with scoliosis do not engage in regular physical activity.)
Severe Scoliosis (over 70 degrees). If the curvature exceeds 70 degrees, the severe twisting of the spine that occurs in structural scoliosis can cause the ribs to press against the lungs, restrict breathing, and reduce oxygen levels. The distortions may also affect the heart and possibly cause dangerous changes.
Very Severe Scoliosis (Over 100 degrees). Eventually, if the curve reaches over 100 degrees, both the lungs and heart can be injured. Patients with this degree of severity are susceptible to lung infections and pneumonia. Curves greater than 100 degrees increase mortality rates, but this problem is very uncommon in America.

Some experts argue that simply measuring the degree of the curve may not identify patients in the moderate and severe groups who are at greatest risk for lung problems. Other factors (spinal flexibility, the extent of asymmetry between the ribs and the vertebrae) may be more important in predicting severity in this group.

Scoliosis is associated with osteopenia, a condition characterized by loss of bone mass. About 27 - 38% of adolescent girls who have scoliosis also have osteopenia. Some experts recommend measuring bone mineral density when a patient is diagnosed with scoliosis. The amount of bone loss may help predict how severely the spine will curve. Preventing and treating osteopenia may help limit further curve progression.

If not treated, osteopenia can later develop into osteoporosis. Osteoporosis is a more serious loss of bone density that is common among postmenopausal women. Adolescents who have scoliosis are at increased risk of developing osteoporosis later in life. [See In-Depth Report#18: Osteoporosis.]

Osteoporosis is a condition characterized by progressive loss of bone density, thinning of bone tissue, and increased vulnerability to fractures. Osteoporosis may result from disease, dietary or hormonal deficiency, or advanced age. Regular exercise and vitamin and mineral supplements can reduce and even reverse loss of bone density.

After 20 years or more, scoliosis patients who were previously treated with surgery experience small but significant physical impairment, (mainly mild back problems), compared to their peers without scoliosis. In one study, 65% of patients reported some low back pain compared to 47% of people without a history of scoliosis. In general it was mild, although 45% of patients reported having to take days off from work compared to 19% of nonscolosis patients. In another study, only 1.5% of the scoliosis group had severe debilitating back pain. In general, the quality of life was similar, however. Pain also did not play a major role in social limitations.

The following are some possible causes of later back problems in people with a history of treated scoliosis:

Spinal fusion disease. Patients who are surgically treated with fusion techniques lose flexibility and may experience weakness in back muscles due to injuries during surgery.
Disk degeneration and low back pain. With disk degeneration, the disks between the vertebrae may become weakened and rupture. In some patients, years after the original surgeries, particularly with the first generation of the Harrington rods, the weight of the instrumentation can cause disk and joint degeneration severe enough to require surgery. Treatment may involve removal of the old instrumentation and extension of the fusion into the lower back. Still, most patients do not experience significant back pain from these problems.
Height loss.
Scarred regions. Pain can occur from old scars in the incision areas.
Lumbar flatback. This condition is most often the result of a scoliosis surgical procedure called the Harrington technique, which eliminated lordosis (the inward curve in the lower back). Adult patients with flatback syndrome tend to stoop forward. They may experience fatigue and back and even neck pain.
Rotational trunk shift (uneven shoulders and hips).

Evidence suggests that previous treatment with braces may also cause mild back pain and more days off, but problems appear to be less than with surgery. In one study, dysfunction was comparable to people without a history of scoliosis.

Pain in adult-onset or untreated childhood scoliosis often develops because of posture problems that cause uneven stresses on the back, hips, shoulders, necks, and legs. In one study conducted 20 years after growth had stopped, two-thirds of adults who had lived with curvatures of 20 - 55 degrees reported they experienced back pain. Other studies have reported that adults with a history of scoliosis tend to have chronic and more back pain than the general population.

Nearly all individuals with untreated scoliosis at some point develop spondylosis, an arthritic condition in the spine. The joints become inflamed, the cartilage that cushions the disks may thin, and bone spurs may develop. If the disk degenerates or the curvature progresses to the point that the spinal vertebrae begin pressing on the nerves, pain can be very severe and may require surgery. Even surgically treated patients are at risk for spondylosis if inflammation occurs in vertebrae around the fusion site.

Emotional Impact in Childhood. The emotional impact of scoliosis, particularly on young girls or boys during their most vulnerable years, should not be underestimated. Adults who have had scoliosis and its treatments often recall significant social isolation and physical pain. Follow-up studies of children who had scoliosis without having strong family and professional support often report significant behavioral problems. Fortunately, current treatments are solving many of the problems that previous generations had to deal with, including unsightly bracing and extremely painful surgeries with little pain control.

Emotional Effects in Adults. Of some concern are growing numbers of adults with scoliosis. This group experiences considerable problems in general health, social functioning, emotional and mental health, as well as pain.

Older people with a history of treated scoliosis may carry negative emotional events into adulthood that have their roots in their early experiences with scoliosis. Many studies have reported that patients who were treated for scoliosis have limited social activities and a poorer body image in adulthood. Some patients with a history of scoliosis have reported a slight negative effect on their sexual life. Pain appears to be only a minor reason for such limitation.

Women who have been successfully treated for scoliosis have only minor or no additional risks at all for complications during pregnancy and delivery. A history of scoliosis also does not endanger the child. Pregnancy itself, even multiple pregnancies, does not increase the risk for curve progression. Women who have severe scoliosis that restricts the lungs, however, should be monitored closely.

Some evidence suggests a slightly higher risk for breast cancer and leukemia in patients who had multiple x-rays. Risks are highest in patients who had the largest radiation exposure, such as those who had been surgically treated.

Patients who simply received x-ray series for untreated idiopathic scoliosis or scoliosis caused by uneven length legs or hip abnormalities have a very low risk for future complications.

Symptoms

Scoliosis is usually painless. The curvature itself may often be too subtle to be noticed, even by observant parents. Some parents may notice abnormal posture in their growing child that includes:

A tilted head that does not line up over the hips
A protruding shoulder blade
One hip or shoulder that is higher than the other, causing an uneven hem or shirt line
An uneven neckline
Leaning more to one side than the other
In developing girls, breasts appearing to be of unequal size
One side of the upper back being higher than the other when the child bends over, knees together, with the arms dangling down

Scoliosis may be suspected when one shoulder appears to be higher than the other, there is a curvature in the spine, or the pelvis appears to be tilted. The treatment of scoliosis can involve the use of a brace or surgery. Treatment is determined by the cause of the scoliosis, the size and location of the curve, and the stage of bone growth of the patient.

With more advanced scoliosis, fatigue may occur after prolonged sitting or standing. Scoliosis caused by muscle spasms or growths on the spine can sometimes cause pain. Nearly always, however, mild scoliosis produces no symptoms, and the condition is usually detected by the pediatrician or during a school screening test.

Diagnosis

The severity of scoliosis and need for treatment is usually determined by two factors:

The extent of the spinal curvature. (Scoliosis is diagnosed when the curve measures 11 degrees or more.)
The angle of the trunk rotation (ATR).

Both are measured in degrees. These two factors are usually related. For example, a person with a spinal curve of 20 degrees will usually have a trunk rotation (ATR) of 5 degrees. These two measurements, in fact, used to be the cutoff for recommending treatment. However, the great majority of 20-degree curves do not get worse. Patients do not usually need medical attention until the curve reaches 30 degrees, and the ATR is 7 degrees.

Adam's Forward Bend Test. The screening test used most often in schools and in the offices of pediatricians and primary care doctors is called the Adam's forward bend test.

The child bends forward dangling the arms, with the feet together and knees straight. The curve of structural scoliosis is more apparent when bending over. In a child with scoliosis, the examiner may observe an imbalanced rib cage, with one side being higher than the other, or other deformities.

The forward bend test is used most often in schools and doctor's offices to screen for scoliosis. During the test, the child bends forward with the feet together and knees straight while dangling the arms. Any imbalances in the rib cage or other deformities along the back could be a sign of scoliosis.

The forward bend test, however, is not sensitive to abnormalities in the lower back, a very common site for scoliosis. Because the test misses about 15% of scoliosis cases, many experts do not recommend it as the sole method for screening for scoliosis.

Other Physical Tests.

The patient walks on the toes, then the heels, and then jumps up and down on one foot. Such activities indicate leg strength and balance.
The doctor will check leg length and look for tight tendons in the back of the leg, which may cause an uneven leg length or other back problems.
The doctor will also check for neurologic impairment by testing reflexes, nerve sensation, and muscle function.

Proper diagnosis is important. A misjudgment can lead to unnecessary x-rays and stressful treatments in children not actually at risk for progression. Unfortunately, although measurements of curves and rotation are useful, no test exists yet to determine whether a curve will progress.

Inclinometer (Scoliometer). An inclinometer, also known as a Scoliometer, measures distortions of the torso. The procedure is as follows:

The patient bends over, arms dangling and palms pressed together, until a curve can be observed in the upper back (thoracic area).
The Scoliometer is placed on the back and measures the apex (the highest point) of the upper back curve.
The patient continues bending until the curve can be seen in the lower back (lumbar area). The apex of this curve is also measured.
Measurements are repeated twice, with the patient returning to a standing position between repetitions.
If results show a deformity, x-rays probably need to be performed to determine the extent.

Some experts believe the Scoliometer would make a useful device for widespread screening. Scoliometers, however, indicate rib cage distortions in more than half of children who turn out to have very minor or no sideways curves. They are therefore not accurate enough to guide treatment.

Currently, x-rays are the most cost-effective method for diagnosing scoliosis. Experts hope that accurate, noninvasive diagnostic techniques will eventually be developed to replace some of the x-rays used to monitor the progression of scoliosis. To date, imaging techniques under investigation appear to be fairly accurate for detecting scoliosis in the upper back (the thoracic region), but not scoliosis in the lower back (the lumbar region).

X-Rays. If screening indicates scoliosis, the child may be sent to a specialist who takes an initial x-ray and monitors the child every few months using repeated x-rays. X-rays are essential for an accurate diagnosis of scoliosis in that they:

Reveal the degree and severity of scoliosis.
Identify any other spinal abnormalities, including kyphosis (hunchback) and hyperlordosis (swayback).
Help the doctor determine whether skeletal growth has reached maturity.
X-rays taken when patients are bending forward can also help differentiate between structural and nonstructural scoliosis. Structural curves persist when a person bends over, and nonstructural curves tend to disappear. (Muscle spasms or spinal growths may sometimes cause nonstructural scoliosis that shows a curve on bending.)
Children and young adolescents who have mild curves and in older adolescents who have more severe curvatures but whose growth has stopped or slowed need x-rays every few months to detect increasing severity. Young people who are diagnosed with scoliosis should keep their x-rays indefinitely in case they develop back problems later in adulthood and need to be re-examined.

Magnetic Resonance Imaging. Magnetic resonance imaging (MRI) is an advanced imaging procedure that does not use radiation, as x-rays do. It is expensive, however, and not generally used for an initial diagnosis. MRI can, nevertheless, identify spinal cord and brain stem abnormalities, which some studies indicate may be more prevalent than previously believed in children with idiopathic scoliosis. It also may be particularly useful before surgery for detecting defects that could lead to potential complications.

Because frequent x-rays may be required for young children with scoliosis, parents should be sure that x-ray technicians take all necessary protective measures. Experts are concerned about the long-term effects of radiation on sensitive young organs, particularly about a possible increase in the risk for cancer. Studies have reported an increased risk for cancer in women and men who, because of scoliosis, had been exposed to diagnostic x-rays in their childhood and adolescence.

X-ray techniques have become safer in recent years, and technicians can reduce the hazards with the following simple measures:

Directing x-ray beams through the patient from back to front, rather than the reverse.
Using x-ray filters that absorb some of the beam.
Using fast film to reduce exposure by two to six times.
Placing lead aprons or shields over parts of the body that are not being x-rayed.

There are various methods for determining and classifying the extent of the curve.

Cobb Method. The technique known as the Cobb method nearly always calculates the degree of the curve.

On an x-ray of the spine, the examiner draws two lines: One line extends out and up from the edge of the top vertebrae of the curve. The second line extends out and down from the bottom vertebrae.
The technician then draws a perpendicular line between the two lines.
Measuring the intersecting angle determines the degree of curvature.

The Cobb method is limited because it cannot fully determine the flexibility or the three-dimensional aspect of the spine. It is not as effective, then, in defining spinal rotation or kyphosis. It also tends to over-estimate the curve. Other diagnostic tools are needed then to make a more accurate diagnosis.

Classifying the Curve.Classification of the curve allows the doctor to identify patterns that can help determine treatments, particularly specific surgical techniques. The following are examples:

King Classification. The King classification classifies scoliotic curves as one of five patterns, which can help determine surgical treatments. It has limitations, however, and is not very useful for advanced surgical techniques.
Lenke Classification. Lenke classification takes more features of the curve into consideration and is proving to be more reliable. This includes six curve patterns plus additional factors that modify each of these curves.

Three-Dimensional Modeling Techniques. Advanced computer modeling techniques are able to create three dimensional images using x-rays or other two-dimensional images. They allow doctors to observe the spinal distortions and eventually could reduce the number of x-rays currently needed to monitor scoliosis and help surgeons determine optimal surgical procedures.

Even if the curve is accurately calculated, it still remains difficult to predict whether the scoliosis will progress. A recent report indicates that measuring the nerve conduction activity of the muscles supporting the spine may help predict subsequent progression in children with scoliosis. In addition, computer models are being used to better predict risk. One approach requires measuring 21 radiographic and clinical indicators and entering them into a computer program. The technique takes less than 20 minutes per patient, and studies found it to be up to 80% accurate in determining progression of curvature.

One way of predicting whether or not the curvature will progress is knowing when the child will stop growing:

If the child has years to grow, then the spine has more time to progress.
If the child will stop growing within a year, then progression should be very slight. (However, some progression continues in nearly 70% of curves even after the spine has matured.)

Knowing the child's age is, of course, the first step in estimating the end of growth. In addition, other methods can help predict the end of the growth stage. One method is called the Risser sign, which grades the amount of bone in the area at the top of the hipbone. A low grade indicates that the skeleton still has considerable growth; a high grade means that the child has nearly stopped growing and the curve is unlikely to progress much further. The Risser scale differs between genders, and, in boys, a high grade does not always signify the end of progression.

Screening programs for scoliosis, which began in the 1940s, are now mandatory in middle or high schools in many states, but there is considerable debate over whether screening should be routine.

Arguments Against Routine Screening. The U.S. Preventive Services Task Force does not recommend routine screening to detect adolescent scoliosis for the following reasons:

Screening tests are not accurate and depend too much on the skill of the examiner.
Schools often refer children with minor curves who are not at any risk for a progressive or serious condition to doctors, and such over-referrals add considerably to the costs of the health system. In one major study, 94% of the children referred to a doctor by the school did not require treatment. (Over 2,000 children were screened in order to find only 5 children who did need treatment.)
A long-term study of untreated patients with late-onset scoliosis indicates that these patients are productive and functional at a high level at 50-year follow-up. Patients with scoliosis have no greater danger for significant lung problems than the general population until their curves reach 60 - 100 degrees, making early screening unnecessary.

Experts against screening argue that such programs result in early treatments that either will not prevent curve progression and surgery or are unnecessary in the first place since curvatures often do not progress at all.

Arguments for Routine Screening. The American Academy of Orthopaedic Surgeons recommends that girls be screened twice, at ages 10 and 12, and that boys be screened once, at 13 or 14. The American Academy of Pediatrics recommends, however, scoliosis screening at ages 10, 12, 14, and 16 years. (In one study, over 40% of high school sophomores with newly diagnosed scoliosis had shown no signs of the disorder in earlier screening tests.) Other experts make the following arguments for universal screening:

Universal screening is useful for producing information on scoliosis that may eventually lead to knowledge of its cause and ways to prevent it.
Braces have proven to be effective, and early treatment can be important.
Without screening, the chances are slim that children with scoliosis will be diagnosed at an early stage if parents rely only on examinations by a family doctor or pediatrician. Such doctors often do not even look at backs and, if they do, they tend to use only the forward bend test, which is not accurate.

Some experts argue that widespread screening would be cost effective if schools had reasonable guidelines for determining which children should see a doctor for further testing. The following are some suggested guidelines for determining the need for a doctor referral:

Children should be sent to a doctor only if they have a 30-degree curve. (A 20-degree curve with a 5-degree trunk rotation has been the criteria for recommending treatment, although up to 80% of 20-degree curves do not get worse.)
Children with curves between 20 and 30 degrees should be screened every 6 months.

Such guidelines would detect about 95% of all genuinely serious cases while referring only 3% of all children tested for follow-up, thereby cutting costs without jeopardizing children.

Treatment

The treatments for scoliosis are not always straightforward. Some young people do not need treatment at all -- only careful observation. When treatment is warranted, several options, including braces and different surgical procedures, can help.

The general rule of thumb for treating scoliosis is to monitor the condition if the curve is less than 20 degrees. Curves greater than 25 degrees, or those that progress by 10 degrees while being monitored, may require treatment. Whether scoliosis is treated immediately or simply monitored is not an easy decision, however. The percentage of cases that will progress more than 5 degrees can be as low as 5% in certain cases or as high as 50 - 90%, depending on the severity of the curve or other predisposing factors:

Age. In general, the older the child the less likely the curve will progress. Scoliosis in a child under 10, for example, is more likely to progress than scoliosis in an adolescent. Experts estimate that curves less than 19 degrees will progress 10% in girls ages 13 - 15 years and 4% in children older than 15. (In some rare, severe cases, a curve may worsen even after a child has received treatment and stopped growing because of the weight of the body pressing against the abnormal curve.)

Gender. Girls have a higher risk for progression than boys.

Location of the Curvature. Thoracic curves, those in the upper spine, are more likely to progress than thoracolumbar curves or lumbar curves, those of the middle to lower spine.

Severity of the Curvature. The higher the degree of curvature the more likely the chance of progression and the more likely the lungs will be affected. Some experts argue that the degree of the curve alone may not identify patients with moderate and severe scoliosis who are at greatest risk for complications and therefore need treatment. For example, spinal flexibility and the extent of asymmetry between the ribs and the vertebrae may be more important than the curve degree in predicting severity in this group.

Presence of Other Health Conditions. Children in poor health may suffer more from stressful scoliosis treatments than other children. On the other hand, children who have existing conditions and are predispose to lung and heart problems may warrant immediate, aggressive treatment.

For example, a young man of 18 who has a curvature of 30 degrees may require no treatment because his growth has probably almost stopped, and his gender puts him at lower risk. A young girl of 10, however, with the same curvature requires immediate treatment.

In general, the following criteria are used to determine whether a patient should receive braces and conservative therapies or surgery:

Braces tend to be used in children with curvatures between 25 - 40 degrees who still will be growing significantly.
Surgery is suggested for patients with curvatures over 50 degrees, in untreated patients, or when braces have failed. In adults, scoliosis rarely progresses beyond 40 degrees, but surgery may be required if the patient is in a great deal of pain or if the scoliosis causes neurologic problems.

The choice may not be so straightforward in certain cases, and patients should discuss all options with their doctor.

In Children and Adolescents. After a mild curve is detected, a more difficult step is required: predicting whether the curve will progress into a more serious condition. Although as many as 3 in every 100 teenagers have a condition serious enough to need at least observation, progression is highly variable and individual.

In a study of patients whose curves did progress after diagnosis, 34% progressed more than 10 degrees, 18% progressed more than 20 degrees, and 8% progressed more than 30 degrees. Doctors cannot rely on any definitive risk factors for curve progression to predict with any certainty which patients will need aggressive treatment. Some evidence suggests the following factors may help determine patients at lower or higher risk:

Being female, particularly if taller than average.
Being younger at the onset of scoliosis.
Having a greater angle of curvature. For example, at 20 degrees, only about 20% of curves progress. Young people diagnosed with a 30-degree curve, however, have a risk for progression of 60%. With a curve of 50 degrees, the risk is 90%.
Curvatures caused by congenital scoliosis (spinal problems present at birth). These may progress rapidly.
Treatment with growth hormone. (Studies are mixed on whether this treatment poses any significant risk, although strict monitoring is still essential in young patients being given growth hormone.)

Curvatures may be less likely to progress in girls whose scoliosis was low in the back and whose spine was out of balance by more than an inch. Height also comes into play. For example, a shorter-than-average girl of 14 with low-back scoliosis of 25 - 35 degrees but whose spine is imbalanced by over an inch would have almost no risk. The same degree of curvature in the chest region of a tall 10-year old girl whose spine was in balance, however, would almost certainly progress.

In Adults. In rare cases, unrecognized or untreated scoliosis in youth may progress into adulthood, with the following curvatures posing low to high risk:

Curvatures under 30 degrees almost never progress
Predicting progression at curves around 40 degrees is not clear
Curvatures over 50 degrees are at great risk for progression

Managing Scoliosis

Exercise has many health benefits and is important for maintaining strength and muscle tone and stabilizing weight. Stretching exercises may be beneficial in children whose scoliosis is due to uneven leg lengths or a shortened tendon.

Strengthening the Muscles That Turn the Torso. A promising approach focuses on training and strengthening the muscles that turn the torso. Studies using specific equipment (MedX Torso Rotation machine) are showing promise. In a 2003 study, 16 of the 20 patients experienced curve reduction, and no curves progressed. In an earlier study, patients increased strength from 12 - 40%. One girl with a severe lumbar curve required surgery, but the remaining 11 patients had no progression of curvature, and 4 of the patients experienced a reduction in their curvature. Treatment did not involve braces. Clinical trials using this approach are underway. Exercising the torso to build muscle strength is important, in any case, in conjunction with braces.

ASCO Scoliosis Treatment Method. ASCO Scoliosis Treatment Method is a Russian approach that consists of isometric and stretching exercises, vibration, spinal manipulation, and electrical muscle stimulation. Some U.S. centers are reporting success in halting curve progression, but more research is needed to determine possible benefits.

Biofeedback. Researchers have investigated biofeedback on the premise that people receiving a signal to improve posture when slumping may, in some cases, reduce their spinal deformities. (Some experts believe that braces work only because the young patients self-correct their curves by retraining their posture to avoid the discomfort of the brace.)

Chiropractic Care. Several case reports suggest that chiropractic manipulation of the spine may help stop progression of mild curves. However, no rigorous studies have proved this. One small study reported no benefits from chiropractic in girls with spinal curves less than 20 degrees. (About 80% of such curves will not progress significantly without any treatment.)

Airway Ventilation at Night. Some research has focused on the use of airway systems, such as nasal continuous positive airflow pressure, for patients with severe scoliosis and reduced lung capacity. Patients use such systems during the night to force air into the upper airways and into the lungs. In one study, the use of these devices reduced hospitalization and improved lung function, shortness of breath, and fatigue. Such systems also can treat sleep apnea, a common sleep disorder.

Breathing Exercises. Breathing exercises may help improve lung function in children with scoliosis, and signs of lung problems.

When a difference in leg lengths causes secondary scoliosis, adding lifts to the heels may decrease a mild curvature. In one study, this practice reduced the curvature by an average of 5.3 to 7.5 degrees. (Curvatures were all less than 20 degrees.) Patients with the greatest curvature experienced some muscle pain, fatigue, and even nausea during the first few days they were using the lifts, but these symptoms eased within 10 days.

Braces

A brace can prevent further progression of moderate curves of (24 - 40 degrees). However, a brace will almost never reverse an existing curve and is only used to stop progression. One study reported overall success rates of around 74%, but results vary widely depending on the length of time the brace is worn, the type of brace, and the severity of the curve. The great majority of subjects in scoliosis studies are girls. Limited data suggest that in boys compliance rates are low, and braces are not effective.

Compliance with wearing a brace correlates strongly with success rate. In analysis of 34 patients, the compliance rate for the patients whose curve progressed by more than 5 degrees was 62%, while the compliance rate for the patients who did not progress was 85%.

In overweight patients with adolescent idiopathic scoliosis, braces appear to be less effective than in those who are not overweight. In one 10-year multicenter retrospective study, overweight patients were about three times more likely to have an unsuccessful result with braces than were people of normal weight.

A brace is one type of treatment for scoliosis. The brace works by exerting pressure on the back and ribs to push the spine in a straighter position. The brace usually fits snugly around the torso and can come in many styles. In a child who is still growing, bracing is usually recommended to help slow the progression of the curve. The brace is usually worn full-time until the growth of the bones has stopped.

Many experts have questioned whether a brace is any better than nature in halting curvature progress. Early studies found that braces were successful in halting progression in only half of cases (the same rate as no treatment at all). In recent years, however, braces have improved. Many now fit under the arms and can be worn under clothing, so that patients are much more likely to use them for longer periods during the day, which greatly affects their success rates.

Wearing the brace for the prescribed time is difficult but essential for any success. A team approach, with several health professionals involved, is beneficial and often necessary to support the patient through the bracing process. An orthopedic surgeon interprets the x-rays, assesses the potential progression of the scoliosis, and plans the treatment with the patient and family. If a brace is used, an orthotist measures and fits the patient with the device. A physical therapist tailors an exercise program best suited for the patient. A nurse may also coordinate the treatment plans and provide physical and emotional support.

Milwaukee Brace. A full torso brace called the Milwaukee brace was the standard treatment until a decade ago. It is still used particularly for high curves.

The device contains a wide flat bar in front and two smaller ones in back. These bars attach to a ring around the neck that has rests for the chin and back of the head. One study determined that correcting the curve occurs best if the patient lies on their chest when wearing the brace. Some researchers suggest that increasing the tension on the chest straps might add benefit. The brace is also periodically adjusted for growth.

The brace needs to be worn 23 hours a day, with relief during bathing and exercise only. Compliance is a major problem. In one study, only 15% of patients wore the Milwaukee brace as directed. It is a particularly difficult brace to endure wearing; one woman who had worn it for 7 years during adolescence remembered being invisible during her school years, ignored and shunned by other children.

The Boston and TLSO Braces. Molded braces called thoracolumbar-sacral orthoses (TLSOs), most often the Boston brace, come up to beneath the underarms and can be fitted close to the skin so they do not show beneath clothing. It appears to be effective for mid-back and lower curves. In one study, treatment was judged successful in 61% of adolescents who wore Boston braces, and success correlated with wearing the brace more than 18 hours a day. Wearing the brace for 16 hours a day may still be beneficial, although the risk for curve progression is significantly higher the less time the brace is worn. These braces have problems; they are hot, reduce lung capacity by nearly 20%, and cause mild, temporary changes in kidney function.

The Charleston Bending Brace. The Charleston Bending Brace is worn only at night. Some doctors question its value, although it appears to be suitable for small, flexible curves. In a 2002 study, it was equally effective as the Boston brace. Other studies have reported success rates of 56 - 66% in patients who wore the brace as directed. Still, more than 10% of the patients using either brace eventually needed surgery.

Additional Braces in Development. New braces are being developed in an attempt to improve compliance and results. Some examples are:

The Providence brace is a computer-fitted device that is worn only at night. It is specifically designed for the individual curvature abnormalities, and early studies are showing promise.
A bracing method called the SpineCor uses adjustable bands and a cotton vest that allows flexibility. A 2003 study reported that after 2 years, the brace corrected the curve by 5 degrees in more than half the patients, while 38% were stabilized and only 7% had curvature that worsened by more than 5 degrees. A recent trial of 24 girls with idiopathic scoliosis compared the SpineCor with a TLSO-type brace. The study indicated that the SpineCor did not halt curvature progression associated with idiopathic scoliosis during the pubertal growth spurt whereas the TLSO device did.
The custom-fitted TriaC brace exerts pressure in specific areas of the back to allow greater comfort and flexibility. It may be less conspicuous than some of the older braces.

Studies are needed to determine if these or other new braces provide any additional value.

According to a 2003 study, compliance in wearing the brace averages 65% (although it varied from 8 - 90%). Patients were apt to wear them at night but often wore them sporadically during the day. The quality of life can vary by the type of brace worn. In one study, patients who had the Milwaukee brace reported greater impairment than patients with the Boston, TSLO, or Charleston braces. The choice of brace should be one that will be the most effective for a particular patient with the lowest impact on quality of life. Young people often refuse to wear braces, even the newer models, and emotional support from the family and professionals is extremely important to help a child accept the process and sustain compliance. On a positive note, one study reported that brace treatment did not negatively affect the self images of the adolescents who had to wear them.

For children who require braces, an exercise program helps boost well being, improves compliance with treatment, and keeps muscles in tone so that the transition period after brace removal is easier.

An exercise and physical therapy program is important to maintain or achieve the following:

Chest mobility.
Proper breathing. In one study, young girls who wore the Boston brace and performed aerobic exercises for 30 minutes four times a week experienced improved lung function, whereas lung function declined in girls who did not exercise.
Muscle strength (especially in the abdominal muscles).
Flexibility in the spine. One small study showed that patients who performed exercises improving flexibility in the torso experienced less spinal twisting and had improved curvature.
Correct posture. Practicing correct posture, especially in front of a mirror, is an extremely important part of any physical therapy program. A patient who is accustomed to a curved spine may have the sensation of being crooked when first taught to properly align the spine. Practicing in front of a mirror provides a reality check.
Patients must also learn to conduct daily activities while wearing the brace. Patients tend to comply with physical therapy in the period when the brace is first being used. They typically stop exercising when they have gotten used to the brace, however, and resume exercising only near the time the brace is being removed. Patients who don't stay with the program throughout the duration of brace use experience a weakening in the back at the time of removal.

Surgery

The goals of scoliosis surgery are threefold:

Straighten the spine as much as possible in a safe manner
Balance the torso and pelvic areas
Maintain correction

It takes a two-part process to accomplish these goals:

Fusing (joining together) the vertebrae along the curve
Supporting these fused bones with instrumentation (steel rods, hooks, and other devices) attached to the spine

There are many surgical variations that use different instruments, procedures, and surgical approaches to treat scoliosis. All of the operations require meticulous skill. In most cases, success depends less on the type of operation than on the skill and experience of the surgeon. The cause of scoliosis often determines the type of procedure. Parents of patients or adult patients should not be shy in asking the surgeon and hospital about their experience with the specific procedures being considered.

Surgery is usually recommended for the following children and adolescents with idiopathic scoliosis:

All young people whose curve exceeds 50 degrees.
Growing children whose curve has gone beyond 40 degrees. (There is still some debate, however, about whether all children with curves of 40 degrees should have surgery.)
Older children who have surgery tend to experience improved well-being from the changes in their appearance, even if they have no actual improved physical functioning.

Surgery may be required for the following children at as early an age as possible.

Those whose scoliosis is due to inborn abnormalities. (The younger they are when surgery is performed the better their chances for success.)
Children with multiple physical handicaps.

Procedures will differ depending on whether a child has idiopathic scoliosis, or scoliosis due to muscle and nerve disorders (such as muscular dystrophy or cerebral palsy). In the latter cases, children also need a team approach to reduce their risks for serious complications.

Before the operation, a doctor conducts a complete physical examination to determine leg lengths, muscle strength, lung function, and any postural abnormalities. The patient receives training in deep breathing and effective coughing to avoid lung congestion after the operation. The patient should also receive training in turning over in bed in a single movement (called log-rolling) before the operation. Psychologic intervention using cognitive-behavioral methods that help young patients cope may be very helpful in reducing anxiety and pain after surgery.

Patients are encouraged to donate their own blood before the operation for use in possible transfusions. The patient should have no sunburn, rashes, or sores on the back before the operation, which could increase the risk for infection.

Most scoliosis operations involve fusing the vertebrae. The instruments and devices used to support the fusion vary, however.

In the fusion procedure, the surgeon will:

Slice flaps to expose the backs of the vertebrae that lie along the curve.
Remove the bony outgrowths along the vertebrae that allow the spine to twist and bend.
Lay matchstick-sized bone grafts vertically across the exposed surface of each vertebra, being careful that they touch adjoining vertebrae.
Fold the flaps back to their original position, covering the bone grafts.
These grafts will regenerate, grow into the bone, and fuse the vertebrae together.

Depending upon the severity and responsiveness to other treatment, a doctor may recommend surgery for scoliosis. Surgery involves correcting the curve (although not all the way) and fusing the bones in the curve together. The surgeon lays bone grafts across the exposed surface of each vertebra. These grafts will regenerate, grow into the bone, and fuse the vertebrae together. The bones are held in place with one or two metal rods held down with hooks and screws, helping to support the fusion of the vertebrae.

Graft Materials. A surgeon takes bone grafts from the patient's hip, ribs, spine, or other bones (called autografts). This is the best quality bone. However, because autografts are taken directly from the scoliosis patient, the operation is longer and the patient experiences more pain afterward. Researchers are investigating allografts, bone grafts taken from another person or a cadaver. This would reduce the pain and duration of the operation. Allografts, however, pose an increased risk for infection from the donor.

Some surgical centers now perform spinal fusions in adults using a biologically-manufactured human bone protein instead of bone grafts. RhBMP-2 (INFUSE Bone Graft) contains a bone morphogenetic protein (BMP) that helps the body grow its own bone. A surgeon inserts the protein into a pair of thimble-like cages, which are implanted between the spinal vertebrae. The cages help stabilize the spine, while the protein prompts new bone growth. Doctors hope that this new procedure can eliminate the pain of autografts and the risk of infection of allografts. Results from preliminary studies have been promising. BMP treatments are currently approved only for adults.

Healing. The healed fusions harden in a straightened position to prevent further curvature, leaving the rest of the spine flexible. It takes about 3 months for the vertebrae to fuse substantially, although 1 - 2 years are required before fusion is complete. Fusion stops growth in the spine, but most growth occurs in the long bones of the body (such as in the legs), anyway. Patients will most likely gain height from both growth in the legs and from the straighter spine. Patients may walk at a slightly slower pace after fusion, but balance may improve, and sports activities are not restricted after the procedure.

Harrington Procedure. Until 10 years ago, the standard instruments used in fusion procedures were those of the Harrington procedure, first developed in the 1960s:

To support the fusion of the vertebrae, the surgeon uses a steel rod, extending from the bottom to the top of the curve. (More than one rod may be used depending on the type of curve and whether outward curvature of the spine is present.)
The rod is attached by hooks that are suspended from pegs inserted into the bone.
Similar to changing a tire, the steel rod is jacked up and then locked into place to support the spine securely. The surgeon is then ready to fuse the vertebrae together.
After this operation, patients must wear a full body cast and lie in bed for 3 - 6 months until fusion is complete enough to stabilize the spine.
After 1 - 2 years, the steel rod is not really necessary, but it is almost always left in place unless infection or other complications occur.

The Harrington procedure is very difficult to undergo, particularly for young people, and although the operation can achieve a correction of the curve of over 50%, studies have reported a loss in this correction of between 10 - 25% over time. The procedure does not correct the rotation of the spine and, therefore, does not improve an existing rib hump that was caused by the rotation. The operation does not interfere with normal pregnancies and deliveries later in life.

Certain complications may occur from this procedure:

About 40% of Harrington patients have a condition called the flat back syndrome, because the procedure eliminates normal lordosis (the inward curving of the lower back). Flat back syndrome from the Harrington procedure does not cause any immediate pain. In later years, however, the disks may collapse below the fusion, making it difficult to stand erect, and the condition can cause significant pain and emotional distress.
Studies have reported that 5 - 7 years after their surgery, between a fifth and a third of patients who had the Harrington procedure experienced low back pain. (In one study, only 3% had experienced back pain before surgery.) In such cases, however, the pain was not severe enough to interfere with normal activities and did not require additional surgery.
Children younger than age 11 whose skeleton is immature and who have the Harrington procedure have a fairly high risk for a specific curve progression called the crankshaft phenomenon. This condition occurs when the front of the fused spine continues to grow after the procedure. The spine cannot grow longer, so it twists and develops a curvature. In one study that followed patients for 5 - 16 years, crankshaft curve progression was moderate, however, with the Cobb angle averaging 9 degrees and rotation averaging 7 degrees.

Cotrel-Dubousset Procedure. The Cotrel-Dubousset procedure not only corrects the curve but also may help correct rotation, and it does not cause flat back syndrome.

With this procedure, a surgeon cross links parallel rods for better stability in holding the fused vertebrae. Improvement in correction averaged 66% in one study, with a later correction loss reported to be 5%. (Other studies have reported loss of curvature correction at less than 2%.) Over 95% of patients reported the results to be good or very good (only 86% of patients who had the Harrington procedure experienced the same levels of satisfaction). Patients often go home in 5 days and may be back in school in 3 weeks.

Complication rates are similar to the Harrington procedure but with some differences:

Operation time and blood loss are greater than with the Harrington procedure.
Cotrel-Dubousset and other procedures that are designed to reverse the rotation of the spine have less risk for flat back syndrome, but they have a higher risk for spinal imbalance than the Harrington procedure.
Failure rates are about 25% after 10 years, which is very high. Experts hope that the advances in current scoliosis procedures will help reduce the long-term adverse effects.

The Texas Scottish-Rite Hospital (TSRH) Instrumentation. The Texas Scottish-Rite Hospital (TSRH) instrumentation is similar to the Cotrel-Dubousset procedure in that it uses parallel rods and other devices that reverse rotation as well as improve curvature. TSRH, however, uses smooth rods and hooks that are designed to make removal or adjustment easier later on if complications arise. Complications are similar to the Cotrel-Dubousset procedure.

Additional Forms of Instrumentation. Other instrumentation procedures have refined the hardware used in the Harrington and Cotrel-Dubousset operations.

After surgeons developed Luque instrumentation to help maintain normal lordosis, experts hoped that bracing would not be needed afterward. Several studies showed, however, that without braces, correction was lost after this operation, and the procedure may have a higher risk for spinal cord injury than other standard procedures. Luque instrumentation is used primarily in people whose scoliosis is due to problems of nerves and muscles, such as in children with cerebral palsy.
Wisconsin segmental spine instrumentation (WSSI) is as safe as the Harrington rod and nearly as strong as the Luque instrumentation.
The Dorsal Dynamic Spondylodesis (DDS) system, under testing in Germany, is a semirigid system that allows for greater flexibility of the spine.

Instrumentation for Anterior Approach. The anterior approach, in which the surgeon performs the operation by opening the chest wall, requires specific hardware. Halm-Zielke instrumentation, for example, uses TSRH instrumentation with bone grafts constructed from ribs to prop open the spaces between the disks. It allows true three-dimensional curve correction. However, it does not solve specific problems with this approach -- higher risks for kyphosis (an outward curve) and pseudoarthrosis (a false joint at the fusion site). Variants using two rod systems, fusion cages, or other instruments appear to improve this procedure.

Posterior Approach (Through the Back). Many surgeons use a posterior approach for scoliosis, which reaches the surgical area by opening the back of the patient. It has been the gold standard for decades and is generally used with Harrington instrumentation. The posterior approach has advantages and disadvantages:

Advantages. Surgeons are familiar with it, so fusion rates are excellent, curve correction is good, and it has few complications.
Disadvantages. Preadolescent children are at risk for the crankshaft phenomenon (a worsening of the curve) later on. (Newer posterior instrumentation, such as the Isola instrumentation, may prevent this occurrence.) The posterior approach also does not always correct hypokyphosis (the loss of normal outward curvature) in the thoracic (upper) spine. The procedure is not always effective for curves in the thoracolumbar region (where the upper and lower spine meet) and may cause spinal abnormalities there.

Anterior Approach (Through the Front). Increasingly, surgeons are using the anterior approach, in which the surgeon performs the operation through the chest wall (called a thoracotomy). With the anterior approach, the surgeon makes an incision in the chest, deflates the lung, and removes a rib in order to reach the spine. This rib can be used during the operation as a strut to support the spine. It also may be repositioned within the patient until it is used for bone grafting during fusion.

The anterior approach also has its advantages and disadvantages:

Advantages. Because the frontal approach allows the procedure to be performed higher up in the spine than with standard procedures, the patient may have a lower risk for lower-back injury later on. In addition, transfusion rates are much lower with the anterior approach. With increasing experience, the anterior approach is as effective as the posterior approach.
Disadvantages. It is a more recent procedure than the posterior approach, and, among inexperienced surgeons, carries a higher risk for complications than in the more standard posterior approach. One study noted poorer lung function 2 years after surgery than with the posterior approach, possibly because the wide chest incision impairs the chest muscles, which can affect lung function afterward. Anterior instrumentation poses a risk for hyperkyphosis (exaggerated outward curvature) and a higher risk for pseudoarthrosis, a painful condition in which a false joint develops at the fusion site. Hardware failure rates may also be higher in the anterior approach than in the posterior approach. Increasing experience and newer hardware designs are reducing many of these problems.

The Combined Anterior-Posterior Approach. The combination approach uses an anterior approach first, which allows better correction of the problems. The fusion part of the operation is done with the posterior approach. This is a very long and complex procedure. It appears to be safe, however, and is proving to be useful, even in very young patients, for preventing the crankshaft phenomenon. It also may correct large rigid curves and specific severe curves in the thoracic spine.

Researchers are evaluating new approaches to treating thoracic scoliosis in adolescents and children. Researchers in Germany are studying the effects of implanting a vertical expandable prosthetic titanium rib. This implant expands the thoracic cavity, thereby correcting the curvature and allowing spinal, thoracic, and lung growth. Early experience with 15 children showed improvement of thoracic insufficiency syndrome and ability to sit, in addition to greatly improvement cosmetic appearance.

Researchers in the U.S. recently compared the radiographic and clinical outcomes and pulmonary function in patients treated with either anterior thoracoscopic or traditional posterior surgery. The anterior thoracoscopic surgery uses a video-assisted anterior approach and recently developed spinal instrumentation. There were 28 patients in the thoracoscopic group (average, 14.6 years of age) and 23 patients in the posterior fusion group (average, 14.3 years of age). The researchers found no significant differences between the groups in terms of kyphosis, coronal balance, or tilt angle. Advantages of the anterior thoracoscopic approach include the need for fewer vertebral levels fused, less blood loss, and lower transfusion rate, yet the operative time was nearly 2 times longer than for the posterior approach.

While both of these new treatments have shown some early positive results, more research will be needed to determine their true value.

Complication rates are high (nearly 10%) with any of these procedures, including the standard Harrington method and the newer Cotrel-Dubousset procedure.

Complications for all procedures include allergic reactions to anesthesia and the following:

Bleeding. Standard procedures increase the risk for major blood loss during the procedure. Patients are encouraged to donate blood before the operation for use in possible transfusions. Children sometimes require more than one transfusion following surgery. Researchers are investigating various methods for reducing the need for transfusions.

In one study, patients received erythropoietin (rhEPO) before the procedure. RhEPO is a hormone that acts in the bone marrow to increase the production of red blood cells. Patients who received this hormone, particularly those with idiopathic scoliosis, needed fewer transfusions and spent less time in the hospital than those who did not receive rhEPO.

Newer endoscopic techniques are reducing the need for transfusions.

Postoperative Pain. Some pain always follows these procedures, requiring intravenous administration of potent painkillers right after the operation (endoscopic procedures may require only mild pain relievers). Of some concern is a study suggesting that the use of NSAIDs, or nonsteroidal anti-inflammatory drugs (aspirin, Motrin, Advil), for pain relief right after fusion may increase the risk for fusion failure. Until more research is conducted, these common painkillers should not be routinely used immediately after surgery.

Infection. Infection is always a risk with any operation. One study reported changes in the immune system for about 3 weeks after surgery, which indicated a greater risk for infection. Researchers recommended being very vigilant for signs of infection, including in the pancreas and urinary tract. Doctors also recommend antibiotics, given by injection for 2 - 5 days after surgery and by mouth for 1 - 2 weeks longer.

Nerve Damage. Patients often worry about neurologic injuries, but the risk is actually very low. In general, nerve injury occurs in 1% of patients, with the risk highest in adults. If neurologic damage occurs, it most often causes muscle weakness. Paralysis is very rare and can be prevented using monitoring techniques during the operation. Nearly all monitoring procedures use a so-called wake-up test, in which the patient is brought out of anesthesia during or at the end of the procedure and assessed for sensations to be sure no injury has occurred. One simple method is to wake patients up in the middle of their operations and ask them to wiggle their toes. More sophisticated methods measure the electrical activity of the spinal cord; if the monitor indicates a fall in electrical response and possible injury, the surgeon adjusts his techniques to avoid further damage to the spinal cord.

Pseudoarthrosis. If the fusion fails to heal, pseudoarthrosis, a painful condition in which a false joint develops at the site, may develop. In one study, teenagers who smoked and heavier adolescents (over 154 pounds) who had hyperkyphosis (hunchback) were at higher risk for this complication. The anterior approach may pose a higher risk for pseudoarthrosis. One study reported that pseudoarthrosis may be undiagnosed, and rates may average 20% after surgery, therefore acting as a major contributor to post-surgery pain.

Disk Degeneration and Low Back Pain. Fusion in the lumbar area produces great stress on the lower back and eventually can cause disk degeneration. Loss of trunk mobility, balance, and muscle strength from surgical treatments can also cause lower back pain and chronic problems in future years. Patients who are surgically treated with fusion techniques lose flexibility; their back muscles may be weakened if they were injured during surgery. In most cases, however, the consequences are mild to moderate.

Lung Function. Some patients may develop serious lung problems after surgery. These complications are highest in children whose scoliosis is due to neuromuscular problems, such as spina bifida, cerebral palsy, or muscular dystrophy. Lung problems can occur up to 1 week after surgery. Lung function may not become completely normal until 1 - 2 months after surgery.

Other Complications. Other problems can include, but are not limited to, the following:

Hooks dislodging or a fused vertebra fracturing
Gallstones
Pancreatitis (inflammation of the pancreas). Among adolescents, this complication tends to occur more often among those who are older or who have a lower body mass index.
Intestinal obstruction

Patients must perform breathing and coughing exercises shortly after the procedure and continue them through the recovery process to rid the lungs of congestion. The patient is usually able to sit up the day after the operation, and most patients can move on their own within a week. A brace may be necessary, depending on the procedure. With the anterior approach in the upper back, patients may have some trouble with activities involving the arms and hands -- such as tying shoes and cutting food. In one study, however, occupational therapy using stretching and strengthening exercises allowed for full resumption of daily activities, including dressing, bathing, and grooming, within 3 months.

Patients are often concerned that surgery will stiffen their backs, but most cases of scoliosis affect the upper back, which has only limited movement, so that patients do not notice much difference. It may take a year or more for muscle strength to return. In some cases, the operation cannot completely correct the curve, and one leg may be shorter than the other. Heel lifts may help in this case.

Patients may need a corrective procedure called revision or salvage surgery, usually for one of these reasons:

Failure of the previous procedure
Curvature progression around the fusion site
Disk degeneration
Poor posture alignment

Minimally invasive surgery is an alternative to spinal fusion. These types of surgeries use a few small incisions and cause less scarring than standard open approaches that require wide cuts. However, these surgeries are limited to certain patients and are not yet as frequently performed as spinal fusion surgeries.

Endoscopy. In endoscopy, the surgeon makes small incisions and inserts tubes that contain tiny instruments and cameras through the incisions in order to view and execute the procedure. In most cases, the procedure occurs in two stages:

First, the surgeon uses the anterior approach to remove disk material and loosen the spine.
They follow with a posterior for fusion and instrumentation.

Recovery after surgery is rapid. Most patients are out of bed 2 days after surgery. Endoscopy causes fewer and smaller scars, and an easier recovery, than more invasive surgical approaches.

However, the endoscopic procedure for scoliosis is complicated, and few surgeons are trained to perform it. The surgery is generally used only for single curves in the upper back or for patients with a curve in the upper back and a compensating curve in the lower back. Some surgeons are now able to operate on areas below the diaphragm, including the lumbar spine. The patients must still wear a brace for 3 months after surgery. Long-term studies are required to compare results to those of standard procedures.

Growing Rod Technique. This technique is used for very young children in whom bracing has not helped. Instead of doing spinal fusion, doctors surgically insert a rod into the patient’s back. Additional surgeries are performed every 6 months to extend the rod so that the spine can continue to grow. Some growing rod techniques use a single rod, while others use two rods. Studies suggest that dual rods are stronger than single rods, which may help provide better spinal stability and correction.

Vertebral Body Stapling. Vertebral body stapling is an experimental technique that may prevent curve progression in some young patients with curves less than 50 degrees. It involves stapling the convex (outer) curve of the anterior spine (the side of the spine facing the chest), which helps stabilize and reduce progression of the inner (concave) curve. The procedure uses a special metal device that is clamp-shaped at body temperature but can be straightened when subjected to cold temperatures and inserted into the spine. When warmed up, the staple returns to its clamp shape and supports the spine.

Treatment for Adult Scoliosis

Adults who were surgically treated for scoliosis in their youth are at risk for disk degeneration and spinal fusion failure. In most adults with previous scoliosis, moderate exercise is not harmful and is extremely important for maintaining healthy supportive muscles and preventing disk degeneration. However, people who have only one or two mobile lumbar vertebrae below the area that was fused during surgery should avoid activity or exercise that causes excessive twisting on the spine. Some experts believe this may accelerate spinal degeneration.

In most cases of adult scoliosis, nonsurgical care is preferred if possible. This can include patient education, exercises, and medical treatments. Braces are not useful.

One center reported that epidural steroid injections were a beneficial alternative to surgery in patients with degenerative lumbar scoliosis.

Candidates for Surgery. In general, pain is the most common reason for surgery in adult scoliosis. Surgery may be recommended in the following cases:

Curvatures over 50 degrees with persistent pain.
Surgery is almost always recommended for adults with curvatures over 60 degrees.
Progressive mid and low back curve or low back curve with persistent pain.
Reduced heart and lung function. Most surgeons, however, will not operate on adults with severely impaired lung function and heart failure. Once this has occurred, surgery will not help improve lung capacity and may cause the condition to worsen, at least temporarily.
Significant deformity is present. Adults should not expect to achieve a completely straight spine, however. There is a high risk for nerve damage if the spine is over-corrected, and adult spines are less flexible than children's are. Usually, however, the correction achieves an acceptable cosmetic improvement.

Surgeons prefer to operate on adults under 50 years old, although surgery may be appropriate in some older people.

Standard Scoliosis Procedures in Adult Scoliosis. The procedures involve the following depending on whether the patient had been treated previously or not:

In patients who have not had previous treatment and who have degenerative lumbar scoliosis, the procedure is often a diskectomy (removal of the diseased disks) followed by scoliosis procedures (instrumentation and fusion).
In patients with previously treated scoliosis, the only remedy is removal of the old instrumentation, extension of the fusion, and implementation of new instrumentation and bone grafts.

Surgical procedures in adult scoliosis are complex and undertaken only after careful consideration and all nonsurgical methods have been exhausted. Adults have a much higher risk than children for complications, including pneumonia, infection, poor wound healing, and persistent pain. In addition, procedures in adults often involve fusion in lumbar and sacral areas (the low back), which can cause several complications. Some experts believe that the risks of operations in this area nearly always outweigh any benefits in adults. Most studies on adults have also reported low success rates.

Others argue that without an operation, the back will become unstable and painful. In addition, most studies on adults report on procedures using the old Harrington instrumentation techniques. Advances in instrumentation are increasing success rates in adults.

In a recent study, for example, adults who underwent anterior fusion and instrumentation had excellent results. In another study of newer generation instrumentation, 87% of adult patients reported satisfaction.

Wedge Osteotomy. Researchers are investigating wedge osteotomy in patients with mature spines, as corrective surgery and as an alternative to braces. In this procedure, a surgeon cuts wedges of bone from the concave side of the curve. The surgeon then straightens the spine by inserting a temporary rod and closing the cut sections. The patient needs to wear a brace and restrict activity for about 12 weeks or until the bone has healed. The patient can resume normal activities when a surgeon removes the rod, and the spine is mobile.

Strike a Yoga Pose: Scissor Legs Side Crow

FitSugar — Mon, 15 Dec 2008 08:00:22 -0800

After practicing Side Crow and Straight Legs Crow, you're ready to give this pose called Scissor Legs Side Crow a try. It's similar to One-Legged Arm Balance, but it's a twist instead of a hamstring stretch. As with all arm-balancing poses, it'll take practice, strength, and stability to achieve this pose, so keep trying until you master it.

Sanskrit Name: Koundinyasana B
English Translation: Pose dedicated to the Sage Koundinya
Also Called: Scissor Legs Side Crow

To learn how to get into this acrobatic-looking pose, read more.

Begin squatting down on your mat with your knees and feet together. Rotate your torso to the left and place both palms flat on the ground, shoulder width apart. They should be perpendicular to your thighs.
Spread your fingers as wide as you can and begin to shift to the left, putting some of your weight into your hands. Your outer left knee is going to rest on your right elbow, and your outer left thigh (close to your hip) is going to rest on your left elbow. Think of your arms as the legs of a table, and your left thigh is the tabletop.
Try to keep your knees together as you shift all your weight into your hands and slowly lift your feet off the floor. Then straighten your legs out to the side, coming into Straight Legs Crow
Keep your left leg in contact with both elbows. Then slowly straighten your right leg behind you so it's parallel with your torso. Hold this pose for five even breaths.
Then bring your right leg back on top of your left, bend your knees and lower your feet back to the floor. Rotate your torso over to the right, place your palms on the ground, and try this pose on the right side.

Strike a Yoga Pose: Three-Legged Dog

FitSugar — Fri, 16 Jan 2009 08:00:00 -0800

Downward Facing Dog pose is a total body pose that's great for stretching out your shoulders, lower back, hamstrings, and calves. It can be really difficult at first, but since it's a pose that's done the most often during a class, you can build your upper body strength fast, so it becomes more of a relaxing pose. To make it more challenging, try this fun variation called Three-Legged Dog. It will open your hips and hamstrings, and work on your balancing abilities. Not to mention it's also a great strength-training move for your upper arms and shoulders.

Sanskrit Name: Tri Pada Adho Mukha Svanasana
English Translation: Three-Legged Downward Facing Dog Pose
Also Called: One-Legged Dog

To find out how to get into it, read more.

Begin on your hands and feet in Downward Facing Dog. Then step both feet together so your big toes are touching.
Shift weight into your hands and your left foot equally. Then raise your right leg up to the ceiling. Try to keep your shoulders parallel with the ground and gaze at your left thigh or up toward your belly to help you stay balanced. To feel the stretch in your left hamstring, keep pressing your left heel down toward the ground.
Stay here for five breaths, then lower your right leg down and switch sides.

Balancing Act

FitSugar — Tue, 22 Jan 2008 12:30:00 -0800

Say you want to improve your sense of balance and you don’t have $100 bucks to kick down for a groovy Vew-Do board. There’s still plenty you can do to hone your balancing skills. And it is a great thing to work since your sense of balance begins to decline after age 25. Ahhh . . . balance is wasted on the young.

Here's what you can do:

Start by simply standing on one foot. Hold onto a wall if you need to. Most importantly though, do not lock your knees and keep you ankles soft, too.
To bump this up a notch, try closing your eyes and standing on one leg - this may sound easy but try it right now and see how you do. This is a great exercise if you have weak ankles that tend to sprain easily.

To see how to work your balance while at the gym, just read more.

You can multitask and work your balance by standing on one leg for 8 bicep curls and complete the set by switching legs and doing another 8 bicep curls. Here you will be working your core to stabilize the small muscles around your ankle joints, improving your balancing skills and building stronger arms.
To up the ante on single-leg bicep curls, try alternating bicep curls so your body has to adjust as the side of your upper body does two different things. Or even harder, try them standing on a BOSU.

HEALTH GUIDE REFERENCE FROM A.D.A.M

Definition

Parkinson's disease is a disorder of the brain that leads to shaking (tremors) and difficulty with walking, movement, and coordination.

Alternative Names

Paralysis agitans; Shaking palsy

Causes, incidence, and risk factors

Parkinson's disease was first described in England in 1817 by Dr. James Parkinson. The disease affects approximately 2 of every 1,000 people and most often develops after age 50. It is one of the most common neurologic disorders of the elderly. Sometimes Parkinson's disease occurs in younger adults, but is rarely seen in children. It affects both men and women.

In some cases, Parkinson's disease occurs within families, especially when it affects young people. Most of the cases that occur at an older age have no known cause.

Parkinson's disease occurs when the nerve cells in the part of the brain that controls muscle movement are gradually destroyed. The damage gets worse with time. The exact reason that the cells of the brain waste away is unknown. The disorder may affect one or both sides of the body, with varying degrees of loss of function.

Nerve cells use a brain chemical called dopamine to help send signals back and forth. Damage in the area of the brain that controls muscle movement causes a decrease in dopamine production. Too little dopamine disturbs the balance between nerve-signalling substances (transmitters). Without dopamine, the nerve cells cannot properly send messages. This results in the loss of muscle function.

Some people with Parkinson's disease become severely depressed. This may be due to loss of dopamine in certain brain areas involved with pleasure and mood. Lack of dopamine can also affect motivation and the ability to make voluntary movements.

Early loss of mental capacities is uncommon. However, persons with severe Parkinson's may have overall mental deterioration (including dementia and hallucinations). Dementia can also be a side effect of some of the medications used to treat the disorder.

Parkinson's in children appears to occur when nerves are not as sensitive to dopamine, rather than damage to the area of brain that produces dopamine. Parkinson's in children is rare.

The term "parkinsonism" refers to any condition that involves a combination of the types of changes in movement seen in Parkinson's disease. Parkinsonism may be caused by other disorders (such as secondary parkinsonism) or certain medications used to treat schizophrenia.

Symptoms

Muscle rigidity
- Stiffness
- Difficulty bending arms or legs
Unstable, stooped, or slumped-over posture
Loss of balance
Gait (walking pattern) changes
Shuffling walk
Slow movements
Difficulty initiating any voluntary movement
- Difficulty beginning to walk
- Difficulty getting up from a chair
Small steps followed by the need to run to maintain balance
Freezing of movement when the movement is stopped, inability to resume movement
Muscle aches and pains (myalgia)
Shaking, tremors (varying degrees, may not be present)
- Characteristically occur at rest, may occur at any time
- May become severe enough to interfere with activities
- May be worse when tired, excited, or stressed
- Finger-thumb rubbing (pill-rolling tremor) may be present
Changes in facial expression
- Reduced ability to show facial expressions
- "Mask" appearance to face
- Staring
- May be unable to close mouth
- Reduced rate of blinking
Voice or speech changes
- Slow speech
- Low volume
- Monotone
- Difficulty speaking
Loss of fine motor skills
- Difficulty writing, may be small and illegible
- Difficulty eating
- Difficulty with any activity that requires small movements
- Uncontrolled, slow movement
Frequent falls
Decline in intellectual function (may occur, can be severe)
A variety of gastrointestinal symptoms, mainly constipation.

Note: Initial symptoms may be mild and nonspecific. For instance, the patient may have a mild tremor or a slight feeling that one leg or foot is stiff and dragging.

Additional symptoms that may be associated with this disease:

Depression
Confusion
Dementia
Seborrhea (oily skin)
Loss of muscle function or feeling
Muscle atrophy
Memory loss
Drooling
Anxiety, stress, and tension

Signs and tests

The health care provider may be able to diagnose Parkinson's disease based on your symptoms and physical examination. However, the symptoms may be difficult to assess, particularly in the elderly. For example, the tremor may not appear when the person is sitting quietly with arms in the lap. The posture changes may be similar to osteoporosis or other changes associated with aging. Lack of facial expression may be a sign of depression.

An examination may show jerky, stiff movements, tremors of the Parkinson's type, and difficulty starting or completing voluntary movements. Reflexes are essentially normal.

Tests may be needed to rule out other disorders that cause similar symptoms.

Treatment

There is no known cure for Parkinson's disease. The goal of treatment is to control symptoms.

Medications control symptoms primarily by increasing the levels of dopamine in the brain. The specific type of medication, the dose, the amount of time between doses, or the combination of medications taken may need to be changed from time to time as symptoms change. Many medications can cause severe side effects, so monitoring and follow-up by the health care provider is important.

Types of medication:

Deprenyl may provide some improvement to mildly affected patients.
Amantadine or anticholinergic medications may be used to reduce early or mild tremors.
Levodopa may be used to increase the body's supply of dopamine, which may improve movement and balance.
Carbidopa reduces the side effects of levodopa and makes levodopa work better.
Entacapone is used to prevent the breakdown of levodopa.
Pramipexole and ropinirole are used before or together with levodopa.
Rasagiline is approved for patients with early Parkinson's disease. It may also be combined with levodopa in patients with more advanced cases of the disease. Rasagiline helps block the breakdown of dopamine.
Neupro is a new skin patch that contains the drug rotigotine. This medicine helps dopamine receptors in the brain work better. The patch is replaced every 24 hours. Neupro is approved for persons with early stage Parkinson's disease.

Additional medications to help reduce symptoms or control side effects of primary treatment medications include antihistamines, antidepressants, monoamine oxidase inhibitors (MAOIs), and others.

Good general nutrition and health are important. Exercise should continue, with the level of activity adjusted to meet the changing energy levels that may occur. Regular rest periods and avoidance of stress are recommended, because fatigue or stress can make symptoms worse. Physical therapy, speech therapy, and occupational therapy may help promote function and independence.

Railings or banisters placed in commonly used areas of the house may be of great benefit to the person experiencing difficulties with daily living activities. Special eating utensils may also be helpful.

Social workers or other counseling services may help the patient cope with the disorder and with obtaining assistance (such as Meals-on-Wheels) as appropriate.

Experimental or less common treatments may be recommended. For example, surgery to implant stimulators or destroy tremor-causing tissues may reduce symptoms in some people. Transplantation of adrenal gland tissue to the brain has been attempted, with variable results.

Support Groups

Support groups may help a person cope with the changes caused by the disease.

See: Parkinson's disease - support group

Expectations (prognosis)

Untreated, the disorder progresses to total disability, often accompanied by general deterioration of all brain functions, and may lead to an early death.

Treated, the disorder impairs people in varying ways. Most people respond to some extent to medications. The extent of symptom relief, and how long this control of symptoms lasts, is highly variable. The side effects of medications may be severe.

Complications

Varying degrees of disability
Difficulty swallowing or eating
Difficulty performing daily activities
Injuries from falls
Side effects of medications

Calling your health care provider

Call your health care provider if symptoms of Parkinson's disease appear, if symptoms get worse, or if new symptoms occur. Also tell the health care provider about any possible side effects of medications, which may include:

Involuntary movements
Nausea and vomiting
Dizziness
Changes in alertness, behavior or mood
Severe confusion or disorientation
Delusional behavior
Hallucinations
Loss of mental functions

Also call your health care provider if the condition gets worse and the caregiver is unable to care for the person at home.

HEALTH GUIDE REFERENCE FROM A.D.A.M

Definition

Secondary parkinsonism is similar to Parkinson's disease, but is caused by certain medicines, an different nervous system disorder, or another illness.

Alternative Names

Parkinsonism - secondary

Causes, incidence, and risk factors

Parkinson's disease is one of the most common neurologic disorders of the elderly. The term "parkinsonism" refers to any condition that causes any combination of the types of movement abnormalities seen in Parkinson's disease by damaging or destroying dopamine neurons in a certain area of the brain.

Secondary parkinsonism may be caused by disorders such as a stroke, encephalitis, or meningitis. Other neurodegenerative disorders such as progressive supranuclear palsy, corticobasal degeneration, and multiple systems atrophy can also damage the dopamine neurons and produce this condition.

Medications including antipsychotics such as haloperidol, metoclopramide, and phenothiazine medications are another common cause of secondary parkinsonism.

Less frequently, exposure to overdoses of narcotics or brain damage caused by anesthesia agents (such as during surgery); exposure to toxins, and carbon monoxide poisoning can cause secondary parkinsonism if they damage the brain area that contains the dopamine neurons.

There have been clusters of cases among intravenous drug users who injected a substance called MPTP, which is a byproduct of an improper technique for synthesizing a form of synthetic heroin (fentanyl derivative). These cases are rare and have affected primarily long-term drug users.

Secondary parkinsonism caused by medications like antipsychotics is usually reversible. If it is caused by toxins, infections, drug-related brain damage, or certain other disorders it may or may not be reversible.

Symptoms of parkinsonism may include stiffness of the trunk, arms, or legs, a decrease in facial expression, soft voice, tremor, some forms of paralysis, and certain problems with control of movement.

Although cognitive dysfunction is not a major feature of Parkinson's disease, it may be more prominent in secondary parkinsonism as the diseases that cause secondary parkinsonism more commonly also result in dementia.

Symptoms

Initial symptoms may be mild and nonspecific, such as mild tremor or a slight feeling that one leg or foot is stiff or dragging.

Specific symptoms include:

Muscle rigidity (stiffness or difficulty bending arms or legs)
Unstable, stooped, or slumped posture
Movement difficulties:
- Loss of balance
- Gait (walking pattern) changes
- Shuffling
- Slow movements
- Difficulty beginning to walk, difficulty initiating any voluntary movement
- Small steps followed by the need to run to maintain balance
- Freezing of movement when the movement is stopped, unable to resume movement
Muscle aches and pains (myalgia)
Muscle cramps and dystonia
Shaking or tremors:
- May occur at rest or at any time
- May become severe enough to interfere with activities
- May be worse when tired, excited, or stressed
- Finger-thumb rubbing (pill rolling tremor)
Changes in facial expression:
- Reduced ability to show facial expressions, "mask" appearance
- Staring
- Difficulty moving eyes up and down
- May be unable to close mouth
Voice or speech changes:
- Slow speaking
- Low pitched voice
- Monotone
- Difficulty speaking
Difficulty chewing or swallowing
Loss of fine motor skills:
- Difficulty writing, may be small and illegible
- Difficulty eating
- Difficulty with any activity that requires small movements
- Frequent falls
Mild decline in intellectual function (may occur)

Symptoms that may occur along with the disease:

Signs and tests

The health care provider may be able to diagnose secondary parkinsonism based on the patient's history, symptoms, and physical examination. However, the symptoms may be difficult to assess, particularly in the elderly.

For example, the tremor may not appear when the person is sitting quietly with the arms in the lap. The posture changes may be similar to those caused by osteoporosis or other changes associated with aging. The lack of facial expression may be a sign of depression.

Examination may show increased muscle tone, tremors of the Parkinson's type, and difficulty initiating or completing voluntary movements. Reflexes are usually normal.

Tests are not usually specific for secondary parkinsonism but may be used to confirm or rule out other disorders that may cause similar symptoms.

Treatment

Treatment is aimed controlling symptoms. If the symptoms are mild, no treatment may be required.

If the condition is caused by a medication, the benefits of the medication should be weighed against the severity of symptoms and stopped or changed if they seem counterproductive.

Treatment of underlying conditions (such as stroke, infections) can reduce symptoms.

Medications may be used if symptoms interfere with the ability to perform daily activities. The medication, or dose, timing or combination of medications may need to be adjusted as symptoms change.

Many of the medications used to treat this condition can cause severe side effects, so monitoring and follow-up by the health care provider are important. Secondary parkinsonism tend to be less responsive to medical therapy than Parkinson's disease.

Medications include:

Amantadine or anticholinergic medications
Levodopa/carbidopa
Dopamine agonists

Neupro is a new skin patch that contains the drug rotigotine. This medicine helps dopamine receptors in the brain work better. The patch is replaced every 24 hours. Neupro is approved for persons with early stage Parkinson's disease.

Additional medications include antihistamines, antidepressants, monoamine oxidase inhibitors, or others to help reduce symptoms or control the side effects of primary treatment medications.

Physical therapy, speech therapy and occupational therapy may help promote function and independence, and may help maintain skills and positive attitude and minimize depression.

Simple aids such as railings or banisters placed in commonly used areas of the house, special eating utensils or other devices may be of great benefit to the person experiencing some difficulties with daily living activities.

Social work or other counseling services may help in coping with the disorder, and obtaining assistance as appropriate (such as safety equipment, Meals-on-Wheels, volunteer services or other assistance).

Support Groups

Expectations (prognosis)

The outcome varies and depends on the cause. If the disorder is caused by medications, it is potentially treatable. All other causes are not reversible and, to a greater or lesser degree, progressive.

Complications

Disability, varying degrees
Difficulty swallowing (eating)
Difficulty performing daily activities
Injuries from falls
Side effects of medications
Debilitation and associated conditions:
- Malnutrition
- Aspiration
- Deep vein thrombosis

Calling your health care provider

Call your health care provider if symptoms of secondary parkinsonism develop, recur, worsen, or progress.

Call your health care provider if new symptoms appear in a person with this disorder, including possible side effects of medications: involuntary movements, nausea/vomiting, dizziness, changes in alertness/behavior/mood, severe confusion or disorientation, delusional behavior, hallucinations, loss of mental functions, or any other new symptoms that develop (see also information on potential side effects of the specific medication).

Discuss the situation with your health care provider if you are unable to care for the person at home (after initial treatment).

Prevention

The treatment of conditions that may cause secondary parkinsonism may decrease the risk of its development. Medication use should only be under the supervision of the health care provider and people with conditions that require long-term use of antipsychotics, like schizophrenia, should be carefully monitored to avoid development of irreversible secondary parkinsonism. Newer antipsychotic medications are less likely to cause secondary parkinsonism.

No Equipment Necessary: Two-Minute Headstand

FitSugar — Tue, 17 Jun 2008 14:30:00 -0700

So you've never tried a headstand in your life or you can't balance whatsoever. That's OK. This exercise is all about working your shoulders and upper back and doesn't have much to do with balance. You can do it against a wall so you don't have to worry about falling over, and you can focus all your attention on working your muscles. You'll be feeling this one tomorrow, for sure.

Music: "Salva Me" by Libera

It's important to take this exercise one step at a time. Once you master each step, you can move on until eventually you're balancing upsidedown and holding the headstand on your own. For a detailed description of how to conquer this headstand read more.

Sit on your heels in front of a wall. If your floor isn't carpeted, place a mat down to cushion your head. Interlace your fingers and place your elbows on the ground, bringing your lowest pinky in front of the other pinky, forming a semicircle with your hands.
Place the back of your head against your palms and the top of your head on the floor, so your skull is vertical with the floor. Once your head and forearms feel stable, straighten both legs and walk you feet towards your face as far as you can. Staying here will still work your upper body.
Once you feel ready, lift one leg up, bend your knee, and place your toes on the wall. Feel free to stay here, getting used to being upsidedown, or you can lift your other leg up and place that foot on the wall. You can hold this for two minutes or straighten your legs, allowing the wall to support you. Stay here, feeling the weight of your entire body in your shoulders and back.
If you have your heart set on doing a headstand without a wall then the next step is to move one of your heels off the wall, so your ankle is right over your hip. Then work on moving your other foot off the wall. The wall is there for you if you start to lose your balance.
Wherever you are, try to hold it for two minutes straight. It'll feel really intense, your muscles may quiver and they'll definitely burn a little. Just keep breathing.
After two minutes, slowly release your feet back down to the floor. Lower your head to the ground so your arms and spine take a little rest. When you're ready, keeping your chin tucked, gently lift your torso up. Your head and neck may feel a little tight, so take your time and lift your head when you're ready. Gently turn your head from side to side and do some leisurely head rolls.

Fit's Tip: When doing this exercise, if you start to feel pain in your neck, spine, or anywhere else, release your feet back to the floor immediately.
