Normal muscle tone may range from which to which?

Normal muscle tone may range from which to which?

• A. Flexible to stiff
• B. Flaccid to rigid
• C. Loose to tight
• D. Low to high

Answer: (B)

Muscle tone is the baseline resistance a muscle offers to passive stretch, and it isn’t a single fixed level. In normal function, tone exists on a spectrum—from very low to very high—depending on the muscle, context, and posture. Describing normal tone as ranging from flaccid (low tone) to rigid (high tone) captures this variability and aligns with how clinicians think about the continuum of tone in health. The other options describe more ambiguous or less clinically standard ranges and don’t convey the idea of normal tone spanning from a low-resistance end to a high-resistance end as clearly.
