During anti-gravity hip flexion MMT, which statement describes the setup?

• A. Seated at edge of table with stabilization of opposite pelvis
• B. Side-lying with the tested limb on top
• C. Prone with hip extended
• D. Standing with pelvis stabilized

Answer: (A)

To test hip flexors against gravity, you want the patient in a position that isolates the hip movement while gravity provides resistance. The setup that achieves this is seating the person at the edge of the table and stabilizing the opposite pelvis. Stabilizing the pelvis prevents compensatory movements from the trunk or pelvic tilt, so when the thigh is lifted, the effort comes from the hip flexors (primarily the iliopsoas) rather than from trunk flexion or pelvic motion. The knee is typically flexed to about 90 degrees to reduce substitution by the rectus femoris and keep the test focused on hip flexion. Other positions can either lessen resistance (like side-lying) or invite compensations from balance or trunk movement, which is why the seated setup with pelvic stabilization is the best description for anti-gravity hip flexion MMT.
