Tie the ends of an exercise band together to form a loop. Attach one end of the loop to a secure object, or shut a door on it to hold it in place. Or you can tie a knot in one end of the band and shut the door with the knot on the other side. The band should be at about waist height.
Stand or sit with your unaffected side toward the door.
Hold one end of the band with the hand of your affected arm, and bend your elbow to 90 degrees. Keep your upper arm against your body. You can squeeze a rolled towel between your elbow and your body for comfort. This will help keep your arm at your side.
Start with your forearm across your belly and your shoulder relaxed. Slowly rotate your forearm out away from your body. Keep your elbow and upper arm tucked against the towel roll or the side of your body until you begin to feel tightness in your shoulder. Slowly move your arm back to where you started. Your shoulder should stay relaxed throughout the exercise.
Repeat 8 to 12 times.
It's a good idea to repeat these steps with your other arm.
