Scapular Dyskinesis Description
Scapular Dyskinesis is a alteration in the normal position or motion of the scapula during coupled scapulohumeral movements. It is related to inhibition or disorganization of activation patterns in scapular stabilizing muscles.  The scapula (shoulder blade) positions the shoulder joint and arm in space allowing for the normal motions and activities of the upper extremity.  Scapular dyskinesis occurs then this normal motion and positioning is altered.  Scapular dyskinesis is a common shoulder disorder which may occur on its own, or more frequent occurs with other injuries to the shoulder.  Scapular dyskinesis causes loss of normal retraction and protraction control, loss of scapular elevation and loss of the normal kinetic chain function of the shoulder. 

Scapular Dyskinesis Anatomy
scapulaThe scapula is commonly refered to as the shoulder blade.  The scapula serves as an insertion site for 17 muscles around the shoulder.  The scapula consists of the scapular body, coracoid process and the acromion. 

Scapular Dyskinesis Symptoms
Scapular Dyskinesis causes pain in the shoulder and around the shoulder blade.  This pain is frequently worse with overhead activty or with sports such as throwing sports, volleyball, and swimming. 

Scapular Dyskinesis Treatment
Scapular Dyskinesis is diagnosed based on a detailed history, physical exam and xrays performed by an orthopaedic surgeon, or sports medicine specialist.  

Scapular dyskinesis is generally treated with physical therapy focused on restoring muscle strength and activation patterns around the scapula.  In cases in which there is an underlying shoulder disorder, such as a SLAP tear or rotator cuff tear, surgical treatment of the underlying abnormality is ofen required.  Scapular muscle rehabilitation and therapy is generally ineffective if the underlying abnormality is not first corrected.

Athletes returning to sports after Scapular Dyskinesis should begin with a graduated exercise program.  First they should be pain free with daily activities with full range of motion and at least 85% strength in the injured shoulder compared to the uninjured shoulder.  Exercise begins with throwers ten program following by a gradually return to throwing program for athletes in throwing sports.   The athlete must remain pain free with a graduated exercise program before full return to sports, especially throwing.
