Which statement best describes MMT 0/5?

Which statement best describes MMT 0/5?

• A. No movement or contraction is observed; complete paralysis.
• B. Trace contraction detectable; limb does not move.
• C. Move through full range with gravity eliminated.
• D. Normal strength.

Answer: (A)

In Manual Muscle Testing, muscle strength is graded on a scale from no activity to normal strength. The lowest grade reflects no activation at all: there is no observable movement and no palpable contraction, which is complete paralysis of that muscle group. If any contraction could be felt without movement, that would place it on the next level. If the limb could move through its full range with gravity eliminated, that would be a higher grade, and if it could move against gravity, yet not necessarily against resistance, that would be even higher, and so on up to normal strength. So the description “no movement or contraction observed; complete paralysis” is exactly what the zero grade indicates.
