Which MMT score is considered intact?

Which MMT score is considered intact?

• A. 2/5
• B. 3/5
• C. 4/5
• D. 5/5

Answer: (B)

Muscle strength is graded on a 0–5 scale in manual muscle testing. In this question, “intact” is taken to mean there is functional movement present—specifically, the muscle can generate enough force to move a limb against gravity. That level of function corresponds to moving against gravity but not necessarily with resistance, which is why 3/5 is described as intact in this context. It shows preserved motor function, even though strength isn’t normal. Higher grades (4/5, 5/5) indicate the ability to resist external resistance and reflect stronger, near-normal to normal strength, while lower grades show greater weakness. So the score that best fits the idea of movement against gravity, indicating intact function in this framework, is 3/5.
