How do you test for shoulder adduction?

Conversely, internal rotation and adduction of the shoulder are tested by having the patient reach behind the back and touch the inferior aspect of the opposite scapula. External rotation should be measured with the patient’s arms at the side and elbows flexed to 90 degrees.

What limits internal rotation of shoulder?

Tension in the glenohumeral capsule and ligaments limits rotation of the humeral head. Tension in the inferior capsule for example restricts elevation. Tension in the anterior and posterior portions of the capsule restricts external and internal rotation respectively.

What initiates shoulder abduction?

The supraspinatus muscle originates from the supraspinous fossa of the scapula, passes under the acromion, and inserts on the superior facet of the greater tubercle of the humerus. It is responsible for the initiation of arm abduction and is in control of the motion up to the first 15 degrees of abduction.

What are muscles used for shoulder abduction?
