In the anti-gravity hip abduction test using the second method, where is resistance applied?

• A. Downward on the lateral thigh just proximal to the knee.
• B. Downward on the medial thigh just proximal to the knee.
• C. Upward on the medial shin.
• D. Backward on the knee.

Answer: (B)

In anti-gravity hip abduction testing, you want the resistance to oppose the movement in a way that forces the hip abductors (gluteus medius and minimus) to generate the abduction torque to keep the leg away from the midline. Using the second method, the resistance is applied downward on the medial thigh just proximal to the knee. This setup creates an adduction-directed force at the hip, so the abductors must work to counteract it and hold the leg in abduction. Placing the resistance here also helps keep the pelvis stabilized and keeps the effort focused on the hip rather than the knee or other muscles. The other locations or directions would change the muscle contribution or the mechanics of the test, making this medial-thigh, near-knee, downward resistance the most effective way to isolate and challenge the hip abductors in this method.
