During anti-gravity plantarflexion MMT, who provides stabilization?

• A. Clinician stabilizes the thigh
• B. No stabilization
• C. Stabilization provided by fingertips
• D. Clinician stabilizes the lower leg with the forearm

Answer: (C)

In this test, the goal is to isolate the ankle plantarflexors so the movement happens at the ankle and not at other joints. Stabilizing the distal portion of the leg and ankle with light contact from the examiner’s fingertips provides just enough steadiness to prevent the tibia from moving or the knee from compensating, without adding extra bulk or engaging other muscles. This fingertip stabilization keeps the motion focused at the ankle while the examiner applies resistance to plantarflexion. Using the thigh or forearm for stabilization can recruit or anchor other joints and change which muscles are doing the work, and having no stabilization can lead to substitutions. So, stabilizing with the fingertips is the best approach for an anti-gravity plantarflexion MMT.
