What is the supraspinatus muscle?

Rick Olderman
Physical Therapy
One muscle is more problematic than others when it comes to shoulder pain: the supraspinatus muscle. When you hear people talking about rotator cuff tears or surgery, they're usually referring to the supraspinatus muscle. Tap the top of your shoulder; the bone you feel is the acromion, which forms the "ceiling" of the shoulder joint. Beneath the acromion is the head of the arm bone, which makes up the "floor" of the shoulder joint. The space between the floor and the ceiling is called the subacromial space. This is where the supraspinatus lives and works. This muscle is important for guiding the head of the humerus when you raise your arm, even if it's just a little movement.
