Extension Isotonic

Professional Rationale
This exercise is a scapular stabilization exercise and is recommended for any shoulder pathology as long as the patient is able to move the arm against gravity, is able to complete these pain-free, and does not have any post-surgical restrictions for strengthening against gravity.

Client Rationale
This exercise is used to strengthen your rotator cuff and the muscles that stabilize and control the position of your shoulder blade. The rotator cuff is a group of 4 muscles that help to stabilize (control) the humeral head so that the shoulder can function properly. The shoulder blade stabilizers are a group of muscles that help to rotate the shoulder blade in the correct sequence, as well as keeping it held against the ribcage. These muscles are strengthened by doing high repetitions and little to no weight using specific motions and positions. These exercises are performed in a pain-free range of motion and should not produce any sharp pain.

• Raise arm backward to the level of your hip.
• Slowly return to start position.
