Cadaveric biomechanical study (n=10) testing whether simulated contraction of the long head of the biceps brachii reduces glenohumeral translation. Shoulders were tested in seven positions of elevation and rotation using standardized directional forces, with and without an air-cylinder–applied biceps force, after capsular venting to eliminate negative intra-articular pressure.
