Automatic Multimodal Assessment of Occurrence and Intensity of Pain for Research and Clinical Use

170 patients with rotator cuff syndrome will be filmed abducting and flexing their arms before learning a simple maneuver that alleviates most of the pain 90% of the time. They will then be filmed performing the same abduction and flexion of their arms. The patients will rate their pain on the common 10-point pain scale after abducting and flexing their arms before and after the maneuver.
