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 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. One 11-year follow-up of workers with CTS found that although nerve conduction continued to worsen, symptoms often tended to diminish over time.

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

Carpal tunnel syndrome exacts a psychologic 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 2001 report from the Bureau of Labor Statistics, the amount of time lost due to carpal tunnel syndrome increased by 6% between 1998 and 1999. And, among the major disabling diseases and illnesses, carpal tunnel syndrome was associated with the longest average time away from work (27 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.
