Scapular Dyskinesis

Scapular dyskinesis refers to abnormal movement or positioning of the shoulder blade during arm motion. Rather than a diagnosis itself, it is a physical finding that underlies many shoulder pain syndromes, contributing to impingement, rotator cuff pathology, and shoulder instability. It is especially common in overhead athletes.
