Scapular retraction describes the backward movement of the scapula about the thoracic wall (scapulothoracic joint). As the scapula moves towards the midline it can also be referred to as scapular adduction. The opposite motion is scapular protraction.
The muscles that act as primary movers are the trapezius (horizontal and lower fibers) and the rhomboid major and minor muscles. Subclavius and pectoralis minor serve to control this motion by decelerating the upper limb (which elevates during retraction) 1,2.
