Which statement best describes MMT 5/5?

Which statement best describes MMT 5/5?

• A. Slight weakness present; patient can perform most functional tasks but with reduced maximal strength.
• B. Normal strength; full ROM against maximal resistance; functional activities intact.
• C. Trace contraction present but no movement.
• D. Absence of movement.

Answer: (B)

Manual muscle testing uses a 0–5 scale to rate strength. A grade of five out of five means normal strength: the muscle can generate maximum resistance through the full range of motion, and the person can perform functional activities without difficulty. This is exactly what the statement describes—normal strength, full ROM against maximal resistance, and intact function. The other descriptions correspond to weaker grades: slight weakness would be a 4/5, trace contraction with no movement is 1/5, and no movement is 0/5.
