Therapy goes slower after surgeries where the front shoulder muscles have been cut. Exercises begin with passive movements. In passive exercises, your shoulder joint is moved, but your muscles stay relaxed. Your therapist gently moves your joint and gradually stretches your arm. You may be taught how to do passive exercises at home.
Active therapy starts three to four weeks after surgery.
You may begin with light isometric strengthening exercises. These exercises work the muscles without straining the healing tissues. At about six weeks you start doing more active strengthening. Exercises focus on improving the strength and control of the rotator cuff muscles and the muscles around the shoulder blade. Your therapist will help you retrain these muscles to keep the ball of the humerus firmly in the socket.
