In gravity-minimized knee flexion MMT, what is the test position?

• A. Side-lying with tested limb on top, with lower limb slightly flexed for stability
• B. Supine with knees extended
• C. Seated with knee flexed off edge
• D. Prone with knee extended

Answer: (A)

In gravity-minimized testing, you position the body so gravity doesn’t significantly help or resist the movement, letting the tester gauge the muscle’s true capability. For knee flexion, this is best done with the patient lying on their side and the leg being tested on top. The bottom leg is slightly flexed to provide stability and keep the pelvis from rolling. This setup keeps the movement focused on the knee flexors (the hamstrings) and reduces contributions from other muscles like the hip extensors or trunk, which could otherwise alter the assessment. Other positions tend to place the limb in a way that gravity either aids or opposingly resists knee flexion or introduce compensations from the trunk or hip, making the isolation of the hamstrings less clear.
