Shoulder Adduction


Shoulder adduction is a medial movement at the shoulder (glenohumeral) joint – moving the upper arm down to the side towards the body – see Figure 1.

In anatomical terminology, a medial movement is one that moves part of the body closer to (medial to) the midline of the body.

 The key muscles involved in this movement are the latissimus dorsi and the sternal head of the pectoralis major.  The clavicular head of the pectoralis major, the coracobrachialis, the teres major, and the long head of the triceps brachii also play a weak role.
