Lie on your back with your arm by your side, slightly away from your body. Place a folded towel under the upper arm. Elbow is bent to 90 degrees and hand points towards the ceiling. Hold a stick with both hands so that the palm of the affected side is facing upwards.
Keep your elbow bent during the movement. Rotate your arm outwards as far as you can by assisting with the stick and your other hand. Return to the starting position.
