Scapula Retraction Exercises in Subacromial Pain Syndrome

Subacmial pain syndrome (SPS) is a common cause of shoulder pain and dysfunction in the general population. Exercise interventions is thought as a primary choice in clinical settings. Scapula retraction exercises are commonly recommended as a part of the exercise programs. Applying scapula retraction exercises at varying shoulder abduction angles could restore balance between the scapulothoracic muscles. Since the scapulothoracic muscles dynamically control subacromial space, scapula retraction exercises could further help to maintain AHD during arm elevation. The primary aim of this study is to investigate the initial effect of the scapula retraction exercises on acromiohumeral distance (AHD) at varying shoulder abduction angles and to compare asymptomatic subjects. The secondary aim of this study is to investigate the effect of scapula retraction exercises on AHD values and symptoms (pain and disability) in patients with SPS.
