If you're performing jobs or participating in activities that require repetitive hand movements, you might be at risk for developing carpal tunnel syndrome. The condition, caused by inflammation and irritation in the narrow groove formed by eight small bones and tissue in the wrist, affects an estimated 3.7 percent of the U.S. population, or some 8.1 million individuals. Those most susceptible to the potentially debilitating ailment include mechanics, cashiers, carpenters, grocery store checkers, manufacturing or assembly-line workers, violinists, gardeners, golfers and knitters. Heavy computer use and typing also are suspected of bringing on CTS.
