STRENGTHEN AND BALANCE ROTATOR CUFF MUSCLES AND SCAPULOTHORACIC JOINTS
Your rotator cuff is made up of muscles and tendons that keep the ball (head) of your upper-arm bone (humerus) in your shoulder socket. It also helps you raise and rotate your arm.
- Supraspinatus. This holds your humerus in place and keeps your upper arm stable. And helps lift your arm.
- Infraspinatus. This is the main muscle that lets you rotate and extend your shoulder.
- Teres Minor. This is the smallest rotator cuff muscle. Its main job is to assist with rotation of the arm away from the body.
- Subscapularis. This holds your upper arm bone to your shoulder blade and helps you rotate your arm, hold it straight out and lower it.
