Codman’s exercise [Ernest A. Codman, American surgeon, 1869–1940; L, exercere, to keep at work] , mild exercises for restoring range of motion and function in the arms or shoulders after injury and immobilization of the limbs. The patient flexes the trunk and supports the upper body with the unaffected extremity. The injured extremity hangs free and can be moved in pendulum fashion through motion of the trunk without active contraction of the shoulder muscles.
