SICK is associated with shoulder injuries, including rotator cuff injuries. SICK, sometimes called SICK scapula syndrome, is defined by several factors, including poor position and mechanics of the scapula, and a tight inferior glenohumeral ligament. Athletes who throw overhead are more prone to SICK.

SICK is an acronym that stands for Scapular malposition, Inferior medial border prominence, Coracoid pain, and dysKinesis of scapula.
