pronator syndrome

, Pronator teres syndrome
A neurological disorder caused by entrapment of the median nerve at the elbow. Symptoms and signs include aching in the wrist with a subjective feeling of poor coordination; paresthesias extending into the hand; paresis of the thumb muscles; pain on pronation of the forearm and flexion of the wrist against resistance; and tenderness in the proximal thenar muscles. A positive Tinel's sign over the pronator teres muscles may be present. The disease usually affects the dominant arm in men. The condition may be treated with corticosteroid injections or orthopedic surgery.

Extreme pronations, together with the higher velocities and accelerations required to pick up a six-pack, may be responsible for any cases of pronator syndrome that can be caused by repeated pronation coupled with force.
These extreme motions, if combined with forceful gripping, may increase the likelihood of a bagger developing pronator syndrome or DeQuervain's syndrome.
