The wrist is an ellipsoidal (condyloid) type synovial joint, allowing for movement along two axes. The extensor carpi radialis brevior arises from the common tendon of the lateral condyle and fascia, and, running down parallel to the longior muscle, inserts into the base of the third metacarpal bone. Early Shortening of Wrist Flexor Muscles Coincides With Poor Recovery After Stroke. Attachments: Originates from the medial epicondyle with the other superficial flexors. The muscle passes straight down the anterior and inner surface of the ulna to insert first into the pisiform bone and unciform process and then to continue over to the base of the fifth metacarpal bone. This muscle is also an accessory wrist flexor, aiding the flexor carpi ulnaris, flexor carpi radialis, palmaris longus, flexor digitorum superficialis and flexor pollicis longus muscles to flex the hand at the wrist joint. The tendons are held in place at the wrist by the palmar carpal ligament and the flexor retinaculum. Try wrist curls as a good "bread and butter" exercise. The following is a list of the included tendons and their functions. Fig. A recent study by McCrea et al (11) looked at the effects of phenol on position and velocity components of spasticity in addition to strength in post-stroke elbow flexor spasticity.
