Stand up straight with your gaze directly ahead.
Hold your affected arm by your side, palm facing forward.
Place your other hand across your shoulder and collar bone, and apply some gentle downwards pressure, lengthening your shoulder from your ear.
Extend your wrist backwards, while simultaneously moving your arm backwards.
Keep your elbow straight and your head still throughout this movement.
When you feel some tension begin in your arm, return to the starting position and repeat.
The movement should be fluid.
