ACTION: wrist flexion
REFERRAL: wrist and palm

COMMENTS: All of these muscles attach to the medial epicondyle of the humerus. Strain at this attachment is known as Golfer's elbow. Trigger points in the flexor carpi radialis, the most lateral wrist flexor, refers pain into the lateral part of the wrist. The flexor carpi ulnaris refers pain a bit more medially. The palmaris longus refers pain into the middle of the palm. A great way to work these muscles is to have the client flex their wrist while you apply pressure to the muscle bellies with your thumbs or palm.
