In anti-gravity MMT for ankle plantarflexion, what is the test position and stabilization and resistance?

• A. Test position: single leg stance with 1-2 fingers of each hand helping with balance. Stabilization: provided by fingertips. Resistance: patient performs a heel raise.
• B. Test position: prone with the foot off the edge of a table. Stabilization: clinician stabilizes lower limb on table. Resistance: down at medial border of the forefoot.
• C. Test position: supine with the foot over the table. Stabilization: examiner stabilizes the leg at the knee. Resistance: across the plantar surface of the forefoot.
• D. Test position: seated with knee flexed. Stabilization: therapist's hand on the thigh. Resistance: at the heel.

Answer: (A)

Testing ankle plantarflexion in an anti-gravity setup uses a standing heel raise, because the movement is performed against the person’s own weight. Having the person stand on one leg positions the body so that gravity provides the primary resistance while the plantarflexors (gastrocnemius and soleus) drive the heel rise. Light stabilization with the examiner’s fingertips keeps the limb from shifting or substituting (for example, knee or hip motions) without adding meaningful external resistance. The action being performed—lifting onto the toes in standing—directly engages plantarflexion strength in a functional, gravity-resisted way, which is why this setup is preferred for anti-gravity testing. Other positions described would move testing away from gravity-resisted plantarflexion or rely on different stabilization patterns, which can alter which muscles are loaded or how strength is graded. They’re not representative of the anti-gravity plantarflexion test, where the body’s weight provides the main resistance while the examiner ensures stability and isolates the movement.
