During anti-gravity hip flexion MMT, where is resistance applied?

• A. Distal thigh, just proximal to the knee joint
• B. Proximal thigh near the hip
• C. Calf/ankle
• D. Across the shin

Answer: (A)

The resistance should be applied to the moving segment so the hip flexors must generate torque about the hip to overcome it. For anti-gravity hip flexion, that means pressing on the thigh where it moves most effectively—the distal thigh, just above the knee joint. This location provides a good lever arm at the hip and isolates the hip flexors. Placing resistance on the calf/ankle would recruit ankle or knee actions, and across the shin would involve different muscle groups around the knee. Applying resistance on the proximal thigh near the hip would shorten the lever arm and make the test harder to interpret, potentially blending contributions from other muscles.
