Scapular Dyskinesis Etiology / Epidemiology / Natural History

  • Scapular dyskinesis = alteration in the normal position or motion of the scapula during coupled scapulohumeral movements. Related to inhibition or disorganization of activation patterns in scapular stabilizing muscles.
  • Posteroinferior capsular thightness and scapular dyskinesis may lead to articular surface RTC tears and SLAP lesions.
  • Tenderness over the coracoid may be related to pectoralis minor tendon contracture secondary to scapular malposition.
