O’Brien Test
This test is used to assess for a SLAP lesion
“The patient sits with the test shoulder in 90 degrees of forward flexion, 40 degrees of horizontal adduction, and maximal internal rotation. The examiner stands with one hand grasping the subject’s wrist. The patient horizontally adducts and flexes the test shoulder against the examiner’s manual resistance. The test is then repeated with the subject’s arm in an externally rotated position. Pain or popping in the internally rotated position (but not in the externally rotated potition) is a positive test.”[1]
