Kinematics of Scapular Motion

  • William Ben KiblerEmail author

Abstract

The scapula plays a key role in virtually all aspects of normal shoulder function. Scapular motion is complex as it occurs both physiologically and accessory to humeral motion via multiple translations and rotations. Alterations in scapular position and motion can be found in association with most shoulder injuries and are most commonly known as scapular dyskinesis. Scapular dyskinesis is a nonspecific response to a painful condition in the shoulder rather than a specific response to certain glenohumeral pathology which suggests the condition should be viewed as a physical impairment rather than a diagnostic entity. An understanding of normal scapular motion can assist in identifying abnormalities of scapular motion. Additionally, the scapular evaluation should aid clinicians in applying treatment approaches which are directed at either restoring scapular function or reducing the symptoms created by the dysfunction.

Video Physiological Scapula Winging. Clinical examination of a 16-year-old girl, with physiological winging. Note the poor control of the scapula and entire shoulder girdle. She rapidly fatigues, struggling to even lift the arm. Fortunately with directed physiotherapy she can regain a functional shoulder (Video courtesy of Dr Simon Bell, Melbourne, Australia) (MOV 6229 kb)
