“…34 Riddle et al 34 suggest that a lack of uniform scapular stabilization by testers may lead to this poor interrater reliability. While several other methods have been developed for measuring shoulder IR or posterior shoulder tightness, 1,3,11,24,30,38 they require 2 clinicians to obtain the measurement 30,38 or have equally poor interrater reliability, or do not accurately measure shoulder IR. 1,3,11,15,24 Due to the influence of tightness of the posterior glenohumeral soft tissues on glenohumeral IR 7,13,14,18,27,30,33,37,39,42 and shoulder kinematics, 5,14,16,17,20,23,27,29,30,35,40 stretching of the posterior glenohumeral tissues to restore glenohumeral IR ROM is a common aspect of shoulder rehabilitation.…”
