Which statement best describes MMT 4/5?

Which statement best describes MMT 4/5?

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

Answer: (A)

The main idea tested here is how manual muscle testing grades reflect different levels of muscle strength. A grade of 4/5 means the muscle can move actively against gravity and can tolerate some resistance, but it cannot generate maximal force. In practical terms, there is slight weakness: the person can perform the movement and complete most functional tasks, but the strength is not at normal, full-capacity levels. So the statement that describes slight weakness with the ability to perform most functional tasks but with reduced maximal strength matches this grading. The other descriptions fit other grades: normal strength against full resistance would be a 5/5; no movement suggests paralysis or a 0/5; trace contraction with no movement corresponds to a very low grade (trace).
