In anti-Gravity MMT for Shoulder Horizontal Adduction, where is the resistance applied?

• A. Downward Near the Elbow
• B. Lateral on the Forearm
• C. Outward to the anterior medial aspect of the arm just proximal to the elbow
• D. Upward on the Wrist

Answer: (C)

When testing shoulder horizontal adduction against gravity, you want to oppose the exact movement the subject is producing—pulling the arm across the chest. Place resistance on the moving arm in a direction that pushes it away from that across-the-chest path. The best spot is the anterior-medial aspect of the arm just proximal to the elbow, where you can apply an outward force (away from the midline). This location provides a stable lever and line of resistance that directly counters the horizontal adduction effort, mainly engaging the pectoralis major involved in bringing the arm across the body. Other placements don’t align with the motion as effectively. For example, applying force downward near the elbow or upward on the wrist doesn’t oppose the cross-body movement in a consistent or mechanically advantageous way, and placing resistance on the forearm laterally can be less stable and may alter the recruitment pattern.
