The Subscapularis is a triangle shape muscle that is part of a group of muscles responsible for the movement of the upper arm and shoulder that make up the rotator cuff. Its the strongest muscle in this group of four rotator cuff muscles.. It is located under the shoulder blade (and behind the rib cage) with its function been to stabilize and rotate the shoulder joint and is the most used muscles in the shoulder.
It is a muscles that is most often injured especially in athletes and one of the commonly indicated muscles responsible for shoulder pain. Some signs of a tight subscapularis muscle is often the inward rotation of the shoulders and a “rounded back.”
The inability to raise the arm fully overhead can also indicate a tight subscapularis. Frozen shoulder may also be tied to an overworked subscapularis.
Massage, friction therapy and stretching can make a great difference by eliminating tightness, restoring greater range of motion and freedom from pain. This muscle can also be reached by working on it from under the arm pit.
