Carpal Tunnel Syndrome

Carpal tunnel syndrome is a hand and arm condition in which there occurs the numbness, tingling and other symptoms in the hand. Carpal tunnel syndrome is caused due to pinched nerve in the wrist. There are a number of factors that contribute to carpal tunnel syndrome, including the possible patterns of hands use, anatomy of the wrist and certain underlying health problems. There are tissues surrounding the flexor tendons of the wrist called synovium. These tissues help in the movement of fingers by lubricating the tendons. Carpal tunnel syndrome is caused when there is swelling in these tissues surrounding the flexor tendons in the wrist and due to swelling the pressure is put on the median nerve. This swelling of the synovium make the confined space of the carpal tunnel narrow, and over time, crowds the nerve. The things that contribute to the development of carpal tunnel syndrome are hand used over time, hormonal changes during pregnancy, age; certain medical conditions like rheumatoid arthritis and diabetes and can also be due to heredity. Confirmation of carpal tunnel syndrome is done by electrodiagnostic tests. In this the electrodes are placed on the hand and wrist then small electric shocks are applied and the speed of impulse transfer by nerves is measured.
