What is the MMT grading scale for ankle plantarflexion in anti-gravity?

What is the MMT grading scale for ankle plantarflexion in anti-gravity?

• A. 5 = at least 25 heel raises, 4 = 10-24 heel raises, 3 = 1-9 heel raises, 2 = full ROM without resistance
• B. 5 = at least 25 heel raises, 4 = 15-24 heel raises, 3 = 3-9 heel raises, 2 = full ROM with resistance
• C. 5 = 20 heel raises, 4 = 10-24 heel raises, 3 = 1-9 heel raises, 2 = full ROM without resistance
• D. 5 = at least 25 heel raises, 4 = 10-24 heel raises, 3 = 1-9 heel raises, 2 = full ROM with resistance

Answer: (A)

The test uses the number of heel raises during plantarflexion in anti-gravity to grade strength. The more heel raises you can perform, the higher the grade. Specifically, for plantarflexion against gravity: - A grade of 5 means you can perform at least 25 heel raises. - A grade of 4 means 10–24 heel raises. - A grade of 3 means 1–9 heel raises. - A grade of 2 means you can move through the full plantarflexion range of motion when gravity is not opposing the movement (gravity-eliminated). This is the best description because it matches how anti-gravity plantarflexion strength is quantified by heel-raise counts and distinguishes the gravity-eliminated scenario for the lower grade. The notion of testing with external resistance would apply a different grading context and isn’t part of this anti-gravity scale.
