Summary

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.

Detailed description

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.

Conditions

• Rotator Cuff Injuries

Interventions

Type	Name	Description
BEHAVIORAL	Triangular Forearm Support	The intervention, the Triangular Forearm Support requires drawing the shoulders away from the subject's head and neck. This requires at least a mild force that this action can oppose. The most-favored maneuver is to have patients stand 2 feet away from a wall, interlock their fingers, and place their forearms to form two sides of an equilateral triangle against the wall. They then place their heads within the triangle, the backs of their heads close to or in on contact with the heels of their hands. Then, pressing against the wall with their elbows and forearms, they draw their shoulders as far away from the wall as possible, retaining contact between the wall and the tops of their heads. Subjects remain in this position for 45 seconds, at which time they stand erect and repeat the abduction and flexion maneuver.
BEHAVIORAL	Placebo	Patients will be asked to raise arms overhead for 45 seconds.
