In gravity-minimized MMT for ankle inversion, what is the patient position?

• A. Supine with the tested foot/ankle over the edge of a table
• B. Side lying with the leg over the edge
• C. Prone with foot on the table
• D. Seated with knee bent

Answer: (A)

Gravity-minimized MMT removes the influence of gravity so you can measure the muscle's true strength without it helping or hindering the movement. For ankle inversion, letting the patient lie on their back with the tested foot hanging off the edge of the table positions the foot so gravity doesn’t create a strong inversion or eversion moment and you can apply only a light, controlled resistance to the inward motion. This setup isolates the invertor muscles (like tibialis posterior and tibialis anterior) more effectively than other positions would. Other positions change the line of gravity or leverage, which can either add unintended resistance or assist the movement, making the test less purely gravity-minimized.
