Wrist and finger flexion occur through the action of the flexor muscles and tendons located along the palm side of the forearm, wrist, and hand.

One of the most common hand problems among both golfers and nongolfers alike is Carpal Tunnel Syndrome (CTS). Carpal tunnel syndrome occurs as a result of an injury to the median nerve. As this nerve travels from the forearm to the wrist, it passes through a structure called the carpal tunnel. The wrist bones form the floor of the tunnel, and the ceiling is made up of a very thick ligament (arrow). Packed into the tunnel, along with the median nerve, are most of the flexor tendons en route to the fingers.

The symptoms of carpal tunnel syndrome include numbness and tingling in the fingers, clumsiness, weakness, and sometimes pain.
