The Rotator Cuff

The rotator cuff is one of the most commonly injured muscle groups in the body, specifically the Supraspinatus tendon. 


Although there are many reasons, in practice I frequently find that poor motor control of one or several muscles responsible for shoulder movement and stability to be the culprit. For instance, in order to move the arm away from the body (abduction) we need a properly functioning Deltoid muscle and a stabilized scapula (Serratus Anterior muscle).  If your brain doesn't have good neuromotor control of the Deltoid muscle, it will ask another nearby muscle to do the work.

Which one? Oftentimes, it's the Supraspinatus.

The problem is, the Supraspinatus isn't designed to do this extra work, and eventually it "breaks" from overuse!

The tendon of this overworked muscle takes further abuse when the Serratus Anterior functions poorly. Dysfunction of this muscle may result in the shoulder complex rotating forward and narrowing the sub-acromial space where the Supraspinatus tendon is located. As this space narrows, the Supraspinatus tendon gets "pinched" between the head of the humerus bone and the underside of the Acromion where the clavicle meets the scapula. Now when the Supraspinatus is used, it's not only performing extra work for the Deltoid muscle, but also undergoing excessive wear and tear as it slides through the very tight and narrow sub-acromial space (imagine the friction that occurs while trying to pull a thick shoelace through a very small eyelet).

Injury to the rotator cuff can be difficult to overcome, if you don't learn how to properly engage the muscles of the shoulder. Always have your shoulder pain evaluated to ensure that you are instructed how to control the movement of the shoulder correctly. This will give you the best chance of recovery.
