What is shoulder abduction (isometric)?

Shoulder abduction (isometric)

1. Stand with your affected arm close to a wall.
2. Bend your arm up so your elbow is at a 90-degree angle (like the letter "L"), and turn your palm as if you are about to shake someone's hand.
3. Hold your forearm and elbow close to the wall. Press your elbow into the wall with moderate pressure.
4. Hold for a count of 6.
5. Repeat 8 to 12 times.
6. It's a good idea to repeat these steps with your other arm.
