Brief Summary
Pain pressure measurements, fine wire EMG and real time imaging ultrasound will be used to determine the relationships between motion, pain perception, and mobility in the glenohumeral joint. Muscle activity, joint motion, and pain will be measured pre-post randomized interventions to determine the response to various physical therapy techniques.
