A 45 year old female presented with a two year history of left shoulder pain especially when reaching forward. The patient demonstrated a very limited range of motion, and presented with a functionally inhibited: biceps (long head) and subscapularis muscle. After finding and correcting a neurological tooth, and performing IRT to several teeth, Origin/Insertion technique with IRT was performed to the long head of the biceps and the subscapularis, after which, the patient’s shoulder range of motion increased to about 90% of normal. On the subsequent visit, O/I with IRT was performed to the left posterior deltoid, after which the patient had full pain free range of motion.
