Which statement best describes MMT 5/5?

Which statement best describes MMT 5/5?

• A. Full range against maximal resistance; normal strength.
• B. Normal strength; patient can perform all functional activities and resist maximal force.
• C. Detects slight increase in muscle tone; resistance at end of range.
• D. Absence of movement.

Answer: (B)

In manual muscle testing, a grade of 5/5 means normal muscle strength. The muscle can move through the full range of motion against maximal resistance, and the person can perform all functional activities that require that muscle while resisting strong force. The statement that best describes this is that the muscle has normal strength, and the person can perform all functional activities and resist maximal force. That captures both the full ROM against maximal resistance and the practical ability to use the muscle in functional tasks. The other description mentions full range against maximal resistance but doesn’t explicitly tie in functional capability, which is why the chosen wording is the most complete fit for conveying what 5/5 represents.
