Standing External Rotation 90/90 Position
The individual grasps the band/cable and brings the arm into a position of 90° of abduction while in neutral rotation. Once in the start position, the individual externally rotates the arm concentrically to achieve the 90/90 position. Once in the 90/90 position, the individual is requested to step backward 2–4 steps in an effort to increase tension in the band/cable. The band/cable is then lowered back to the start position to finish.
