What is the AAOS normative end feel and range for shoulder internal rotation?

Explanation:
Internal rotation of the shoulder, measured with the arm at the side, normally reaches about 0 to 70 degrees before the motion ends. The end feel is firm, not hard, because the movement is limited by the tight posterior capsule and glenohumeral ligaments, with soft tissue tension as you approach the limit. This combination—0 to 70 degrees with a firm end feel—matches the AAOS normative data. Options suggesting a shorter or longer range or a hard end feel don’t align with these standard values.
