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

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.

Patients will be asked to raise arms overhead for 45 seconds.
