PINCH GRIP

TEST

​• Test positioning

​The client may sit or stand. The therapist stands next to the client.

​• Action

​The client is instructed to pinch the tips of the thumb and index finger together.

​• Positive finding

​The inability to touch the tips of the thumb and index finger together demonstrates a positive finding.

Touching the pads of the thumb and index finger indicates pathology of the anterior interosseous nerve between the two heads of the pronator muscle.

​• Special considerations & comments

​The anterior interosseous nerve is a branch of the median nerve (C7-8, T1) that innervates the pronator quadratus, flexor pollicis longus, and the first and second components of the flexor digitorum profundus.
