The supraspinatus is a muscle located in the shoulder region and is an important part of the rotator cuff. Synonyms for supraspinatus include the supraspinatus muscle, supraspinous muscle, supraspinatus tendon, and musculus supraspinatus. The muscle connects to the shoulder blade and helps to stabilize the shoulder joint while also allowing for movement and rotation of the arm. Injuries to the supraspinatus can result in pain, weakness, and limited range of motion. Exercise and physical therapy can often help to strengthen the supraspinatus and prevent future injuries.
