In gravity minimized MMT for Shoulder Horizontal Adduction, what is the patient position?

• A. Seated with shoulder abducted 90, neutral rotation, elbow flexed 90, arm supported on table
• B. Seated with shoulder abducted 90
• C. Supine with shoulder abducted 90
• D. Standing with arm at side

Answer: (A)

Minimizing gravity during a shoulder horizontal adduction MMT means positioning the limb so its weight doesn’t load the moving segment. The best setup is seated with the arm abducted 90 degrees, the shoulder in neutral rotation, the elbow flexed 90 degrees, and the forearm supported on a table. With the arm supported, the weight of the arm rests on the table, so any movement tested comes from the muscles responsible for bringing the forearm across the chest rather than from gravity. The 90-degree abduction keeps the motion in the horizontal plane, and neutral rotation prevents compensatory twists that could involve other muscles. Elbow flexion helps align the forearm for true horizontal adduction. In other positions, the arm isn’t supported or gravity acts directly on the limb, which can obscure the true strength of the horizontal adductors.
