Abstract
Abstract Compression of the median nerve is relieved or prevented with a glove having a contoured major surface for receiving a hand for treatment. A wall intersecting the major surface includes a first wall portion for positioning the index finger and a second wall portion for positioning the thumb. The first and second wall portions of the wall meet at a corner. The major surface increases in height along said first and second wall portions with increasing distance from the corner. The hand rests on the major surface with the wrist and fingers extended, and the thumb extended and abducted. This positioning spreads the palm and bends the fingers back, all of which stretches the transverse carpal ligament and enlarges the carpal canal, ultimately relieving pressure on the median nerve, alleviating or preventing symptoms of carpal tunnel syndrome.
