Scapular dyskinesia refers to altered scapular motion or position. Specifically, it may include static or dynamic medial border prominence of the scapula, inferior angle prominence and/or premature elevation of the scapular, and accelerated inferior scapular rotation while lowering the arm. It generally occurs due to muscle imbalance/weakness or as a response to shoulder injury-including glenohumeral instability. Prevalence of scapular dyskinesis is 61% in overhead athletes and 33% in non-overhead athletes. Assessment should include a detailed physical examination including scapula-specific tests: the scapular assistance test (SAT) and scapular retraction test (SRT). Investigations (imaging and nerve conduction studies) should be targeted to identify any underlying shoulder pathology that may be a cause of dyskinesis. The mainstay of treatment for scapular dyskinesis is appropriate treatment of the underlying cause, followed by a supervised physiotherapy program focusing on re-establishing normal scapular motion and stability.
