๐When we raise our arms overhead, the motion is shared between the shoulder joint (glenohumeral joint) and the scapula moving on the rib cage (scapulothoracic joint). This coordinated pattern is known as scapulohumeral rhythm and allows for smooth, efficient motion when reaching overhead.
๐Classically, this rhythm has been described as about two-thirds of the movement coming from the glenohumeral joint and one-third from upward rotation of the scapula.
๐ง More recent research highlights that this ratio can vary between individuals and tasks, but the key idea remains the sameโoverhead elevation requires both humeral motion and scapular upward rotation working together.
๐Thanks to for this amazing cadaver dissection!
