Facial expression and truncal metrics correlate strongly with occurrence and intensity of pain. Rotator cuff syndrome almost invariably gives significant pain, especially with abduction and flexion of the arms. A simple maneuver that alleviates that pain 90% of the time, by activating the subscapularis to perform the function of the damaged supraspinatus muscle. This study strives to correlate facial and truncal characteristics with the ten-point pain scale by correlating the filmed changes in facial and truncal characteristics with the variations in patient-rated pain before and after the pain-controlling maneuver.~Once effective, the maneuver may be repeated for a number of days, after which time patients generally remain pain-free permanently.
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.
