Lay down on your back and hold a stick or wand in both hands such that your elbows are bent with your palms facing up as you grip the stick.
Make sure that your elbow stays close to your side and your upper arm is at right angle to your forearm (like the letter "L").
Holding the wand or stick close to the end of the affected arm, gently move the wand across your body toward the affected arm.
Hold this position for a count of 10 to 20 seconds and relax.
Aim for at least 8 to 10 reps, each time making sure that your arms stay close to the side of your body while you rotate your shoulder.
