Used to determine labral, acromioclavicular (AC), or other anterior shoulder pathology

Steps:

Part one:

Patient forward flexes the arm with the elbow extended. The patient then internally rotates the arm so THE THUMB IS POINTING DOWN. The patient then adducts the arm 5-10 degrees and resists the downward force applied by the examiner.

Test is considered to be positive if: pain produced

Part two:

The arm is in the same position, but with supination.

If pain is resolved with part two, then it is a labral issue.
