What does a 0/5 grade indicate on MMT?

What does a 0/5 grade indicate on MMT?

• A. A palpable contraction with no joint movement.
• B. Movement through the full ROM against gravity.
• C. Movement is possible only with gravity eliminated.
• D. No detectable muscle contraction.

Answer: (D)

In manual muscle testing, strength is graded on a 0–5 scale, and a zero means complete absence of detectable muscle activity. You cannot see or feel any contraction, and there is no movement of the tested joint. If you could palpate even a tiny contraction without any joint movement, that would be a 1/5. Movement through the full range against gravity would indicate a higher grade, not zero. So the statement “No detectable muscle contraction” best fits a 0/5 grade.
