Carpal tunnel syndrome

Description

An in-depth report on the causes, diagnosis, treatment, and prevention of carpal tunnel syndrome.

Alternative Names

Repetitive stress injuries

Prognosis

Carpal tunnel syndrome can range from a minor inconvenience to a disabling condition, depending on its cause and persistence and the individual characteristics of the patient. Many cases of CTS are mild, and when symptoms are of short duration, they often resolve (disappear) on their own. Once a woman with pregnancy-associated CTS gives birth, for instance, the swelling in her wrists and other symptoms almost always subside. Proper treatment of other medical conditions that cause CTS can often help reduce wrist swelling.

In severe untreated cases, however, the thenar muscles at the base of the thumb may whither, and loss of sensation may be permanent. CTS can become so crippling that people can no longer do their jobs or even perform simple tasks at home.

Psychological and Social Effects at Home

Carpal tunnel syndrome exacts a psychological toll. Anyone who cannot use his or her hands is likely to be depressed and suffer from low self-esteem. People may suffer from daily pain. In severe cases, they may be unable to perform ordinary tasks, such as driving a car or carrying groceries. And equally or even more distressing, they may have to give up enjoyable sports and hobbies.

Impact on Work and Livelihood

According to a 2005 report from the Bureau of Labor Statistics, among the major disabling diseases and illnesses, carpal tunnel syndrome was associated with the longest average time away from work (28 days).

Employees with CTS who try to work through the disorder often put more stress on the wrists to compensate for the weakness and pain. The end result is to make the condition worse and impair work performance.

Eventually, the worker with CTS may be forced to give up his or her livelihood. In one study, nearly half of all patients with CTS changed jobs within 30 months of an initial diagnosis. And because of the controversy surrounding the issue of carpal tunnel syndrome and workers compensation, it is not always certain that the worker will receive compensation payments.
