Carpal tunnel syndrome is a common repetitive-work-related injury. It's often seen in those who work on computers for many hours (keyboard or mouse) or perform repeated fine motor movements (tasks requiring grasping, pinching, gripping and so on). What does that have to do with weight training? Certain exercises aggravate carpal tunnel syndrome, which is now prevalent due to the computer's prominence in the workplace.

Carpal tunnel syndrome is the name given to the irritation and compression of the median nerve in the wrist. The nerve travels down the arm and enters the top of the forearm, where it can also be compressed. From there it travels down between the forearm muscles and into the "carpal tunnel." The floor of the tunnel is made up of carpal, or wrist, bones, and its roof is made of the transverse carpal ligament, which is part of a connective-tissue structure. The tendons of the forearm muscles, or wrist flexors, are also located in the carpal tunnel.

Some in health care claim they know why carpal tunnel occurs, but we really don't know. We do know what happens when it occurs, however. The median nerve begins to become inflamed and dysfunctional. Nerve pathology is known as a neuropathy, which makes the accurate term for the condition median neuropathy at the carpal tunnel, but carpal tunnel syndrome, or CTS, is easier for most to remember.
