Which description corresponds to a 2+ (Poor) grade on the MMT strength scale?

• A. Partial ROM in test position
• B. Full ROM against gravity
• C. No contraction felt or seen
• D. Against moderate pressure

Answer: (A)

In manual muscle testing, a 2+ (Poor) indicates the muscle can produce some movement, but only when gravity is eliminated, and that movement is incomplete. That means the limb can go through only part of the available range in the test position where gravity isn’t aiding or opposing the motion.

Why this fits: partial ROM in the test position shows there is some muscle activity, but not enough to move the joint through the full range without gravity. The other descriptions describe stronger or weaker states: moving through the full range against gravity corresponds to a higher grade, no contraction is a score of zero, and resisting a moderate amount of external force indicates a grade around 4.
