procedure: Test your left shoulder by standing with your right arm straight up, then bend your elbow so your hand hangs behind your head. Keeping your upper arm stationary, rest your palm between your shoulder blades. Reach around behind you with your left arm so the palm is facing out and try to touch the fingers of both hands together. Reverse the procedure and repeat with the opposite shoulder.
