Where is resistance applied during anti-gravity scapular adduction testing?

• A. Upward on the forearm
• B. Downward just proximal to the elbow
• C. Lateral near the wrist
• D. Diagonal toward the shoulder

Answer: (B)

In anti-gravity scapular adduction testing, you’re challenging the muscles that pull the scapula toward the spine (the scapular retractors) while gravity helps the movement. The resistance needs to oppose that retraction in a way that stays focused on the scapular muscles and doesn’t recruit other joints or motions. Placing the resistance downward on the forearm just proximal to the elbow creates a downward force that lines up with the retractors’ action and provides a solid lever arm. This makes it harder for the patient to bring the shoulder blade toward the spine and isolates the intended muscles. If the resistance were applied elsewhere—higher up on the arm, near the wrist, or in a diagonal toward the shoulder—the force wouldn’t align with the retraction movement, which could recruit other muscles or make the test less specific.
