Shoulder Impingement

Shoulder impingement happens when your rotator cuff rubs up against (or “impinges on”) or is pinched underneath it by the top outer edge of your shoulder blade, known as the acromion. A rotator cuff tear, for example, might develop from a shoulder impingement if it is not treated. In patients with shoulder impingement syndrome, physical therapists assist in reducing pain and enhancing shoulder motion and strength.

Your rotator cuff will snag or rub on the acromion if you have shoulder impingement. The bursa—the area between the rotator cuff and the acromion—narrows when your arm is raised, increasing pressure. Impingement results from the rotator cuff becoming irritated by the increasing pressure.

While surgery may usually be avoided to address shoulder impingement, it is occasionally advised. If nonsurgical methods do not sufficiently reduce shoulder pain and enhance range of motion, a doctor might advise surgery. Surgery can make greater space for the compressed soft tissues.
