In muscle function testing, what does grade 2 indicate?

• A. Total paralysis
• B. Active movement with full ROM against gravity
• C. Palpable contraction
• D. Normal movement with resistance

Answer: (B)

In this muscle function testing, the level described means the muscle can produce active movement, but only when gravity is eliminated. Put the limb in a position where gravity doesn’t oppose the motion and have the patient move through the full range of motion there. This shows the muscle can generate movement, but it cannot move the joint against the weight of the limb. It’s distinct from no movement at all, or only a palpable contraction without movement, and from movement that can occur against gravity (which requires a higher grade).
