Causes of Carpal Tunnel Syndrome

Although there are many reasons for developing this swelling of the tendon, it can result from repetitive and forceful movements of the wrist during work and leisure activities. Research by the National Institute for Occupational Safety and Health (NIOSH) indicates that job tasks involving highly repetitive manual acts, or necessitating wrist bending or other stressful wrist postures, are connected with incidents of CTS or related problems. Moreover, it is apparent that this hazard is not confined to a single industry or job but occurs in many occupations, especially those in the manufacturing sector. Jobs involving cutting, small parts assembly, finishing, sewing, and cleaning seem predominantly associated with the syndrome. The factor common in these jobs is the repetitive use of small hand tools. CTS can also be due to trauma from repetitive work such as that of supermarket checkers, checkers in other types of stores, assembly line workers, meat packers, typists, word-processors, accountants, and writers.
