The long tube that holds the median nerve that runs from the wrist to the hand and controls finger movement is called the carpal tunnel. According to the American Academy of Family Physicians, a condition called carpal tunnel syndrome sets in when the ligaments and tendons surrounding the tunnel become inflamed. It is a painful and debilitating disorder.
Cause
Repetitive motion is the main cause of carpal tunnel syndrome, according to the American Academy of Family Physicians. The condition can also be caused by an injury to the wrist or by a disease such as diabetes, thyroid disease or arthritis. Women are more likely to develop the syndrome, and usually have a family history of the disorder. People in jobs that require repetitive hand motions are most at risk; these include computer users, musicians, carpenters and assembly line workers.
Symptoms
Pain and numbness are the initial symptoms most people experience. The thumb, middle and index fingers typically are the first to feel the sensations. As the disease progresses, numbness affects the entire hand, and occurs while using the hand and even when sleeping. Pain runs from the wrist through the fingers, and may affect the forearm. The pain usually increases as you use your affected hand, such as when performing rehabilitation exercises.
Significance
Carpal tunnel syndrome is usually not a significant condition, and responds well to medical treatment and home remedies. According to the American Academy of Family Physicians, strenuous exercises usually do not relieve the pain of carpal tunnel syndrome. Instead, patients are advised to learn new ways of performing the tasks that caused the condition. A splint is often prescribed to hold the tunnel in place until the swelling subsides. Ice and rest are the most effective treatments.
Benefits
Stretching and strengthening exercises can help prevent further outbreaks. According to Hand Health Resources, grippers and stress balls only repeat the movements that caused the condition in the first place. Instead, exercises that extend the tendons may be more effective. To stretch and strengthen fingers and hands, use tight rubber bands such as those used to wrap vegetables. Place the rubber bands around your fingers and thumbs below the first knuckles. Expand your fingers outward so that your hand is open and hold for a count of 5; release and repeat 10 times at least once a day.
Warning
Pressing on the nerve to try to stimulate blood circulation and relieve pain can sometimes worsen carpal tunnel syndrome symptoms, according to MayoClinic.com. Nerve gliding exercises, which entail rubbing and massaging the tunnel to stimulate blood flow, are sometimes used to treat the condition, but these often end up causing additional pain and injury to the sensitive area, and may exacerbate the condition.
