The supraspinatus is a small but important muscle located in the shoulder. It is part of the rotator cuff, a group of muscles and tendons that stabilize the shoulder joint. The supraspinatus helps lift the arm and is crucial for overhead movements, making it essential for activities like throwing or reaching. Injuries to the supraspinatus, such as tears or inflammation, can lead to pain and limited mobility in the shoulder. These issues are often seen in athletes or individuals who perform repetitive overhead tasks. Proper strength and flexibility exercises can help maintain the health of the supraspinatus and prevent injuries.
