The influence of scapular retraction and protraction on the width of the subacromial space. An MRI study.
The width and configuration of the subacromial space was studied in retraction and protraction of the shoulder girdle in four healthy subjects by magnetic resonance imaging. The anterior opening of the subacromial space narrowed as the shoulder moved from a retracted to a protracted position.
