Shoulder Transverse Adduction


Shoulder transverse adduction is a medial movement at the shoulder (glenohumeral) joint in a horizontal plane – moving the upper arm towards and across the chest with the back of the arm facing down – 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.
