Which statement best characterizes MMT 0/5?

Which statement best characterizes MMT 0/5?

• A. No movement or contraction is observed; complete paralysis.
• B. Palpable contraction with no limb movement; movement cannot be initiated.
• C. Move through full range against gravity with maximal resistance.
• D. Normal strength with full functional ability.

Answer: (A)

In manual muscle testing, a grade of zero means there is no observable movement and no palpable contraction, indicating complete paralysis of the muscle. This is exactly what the statement describes. If there were any contraction felt without movement, that would be a higher grade; if movement occurred only when gravity was eliminated, that would be a different grade; moving through the full range against gravity or with resistance would be even higher grades, up to normal strength.
