In MMT for knee extension in Anti-Gravity, where is stabilization applied?

• A. The patient's body weight provides stabilization
• B. The pelvis is stabilized by the clinician
• C. The thigh is stabilized against the table
• D. The clinician stabilizes the contralateral leg

Answer: (C)

The key idea is to fix the part of the leg closest to the movement to isolate the muscle being tested. For knee extension in anti-gravity, you want the quadriceps to do the work without the hip or thigh compensating. That’s achieved by stabilizing the thigh against the table so the femur can’t move or rotate as the knee is extended against resistance. Stabilizing the pelvis or relying on the patient’s weight wouldn’t reliably prevent those compensations, and stabilizing the contralateral leg isn’t the proper method here. So, the thigh against the table provides the most direct, consistent stabilization, allowing the test to reflect knee extension strength accurately.
