Summary of some integrated motion
Shoulder Abduction
Abduction involves the 2 : 1 ratio of
glenohumeral abduction to scapular
upward rotation
—the scapulohumeral rhythm.

Shoulder Flexion
This motion involves the typical
scapulohumeral rhythm: a 2 : 1
ratio of glenohumeral flexion
and scapulothoracic upward rotation.

Shoulder Extension
The exact kinematics of this joint varies, depending on the range of
motion through which the shoulder is being extended. The following
movements occur during a pulling motion, beginning at 90 degrees
of shoulder flexion and moving to 10 degrees of extension.
