Abstract

Thenar motor neuropathy (TMN) is a compressive mononeuropathy of recurrent motor branch of median nerve. It is infrequent and may have different pathogenesis. It may be a unique entity of disease or considered a variant of carpal tunnel syndrome involving the motor branch only. We report a case of TMN induced by vigorous massage that applied strong digital pressure in the region of the base of palm and thenar muscles.
