Objective : Intended to augment, and eventually replace the 10 point subjective scale.

Design: Qualified subjects are then randomized to be either sham plus intervention maneuver or simply intervention maneuver. If randomized for the sham group, they are then taught a share maneuver, followed by repetition of videotaping them while they abduct and flex their arms. We then teach whether randomized in the sham group or not, triangular forearm support maneuver, followed by another video taping of the abduction and flexion.

Setting : Inclusion criteria: volunteer subjects> 5/10 pain for MRI confirmed rotator cuff syndrome. Exclusion criteria: previous shoulder surgery, neuromuscular disease, conditions that may cause pain with shoulder flexion/abduction, significant limitations in movement of the face or limbs

Participants : We videotape their facial expressions and bodily movements while they abduct and flex their arms.

Interventions: Both the patients and the examiner (a physiatrist) rate the patient’s pain on a 10 point scale after each abduction and each flexion.
The data are then compiled and presented to artificial intelligence analysis at Carnegie Mellon University, to determine the algorithms that properly predict the amount of subjective pain and the basis of the subjective video data.

Main Outcome Measures: We have so far completed 186 of 200 subjects and have not yet submitted the data to the artificial intelligence analysis.

Results: However, we have done a preliminary investigation on the TFS maneuver, and it does significantly reduce the pain according to the subjects’ and the physicians’ 10-point scale reports.

Conclusions: There are already objective means to determine the vast majority of forest or manufactured facial expressions for pain. If successful, the Objective Quantification of pain will help physicians decide and who does not need opioids, and other pain relieving medications and medical interventions, enable pharmaceutical firms to determine how helpful their medications actually are, and objectively evaluate the effect of various pain relieving surgeries.

Level of Evidence: Level III
