Which statement best describes MMT 2/5?

• A. Move through full range against gravity with no resistance.
• B. Detects trace contraction but no movement.
• C. Move through full range with gravity eliminated; limb can move fully but cannot work against gravity.
• D. Normal strength.

Answer: (C)

The important idea here is testing muscle strength in a gravity-free position to see if the muscle can complete the entire range of motion without help from gravity. When a muscle can move fully only with gravity eliminated, it means the muscle is too weak to work against the downward pull of gravity, but can still move the limb when that pull is removed. This precisely describes a grade where movement can be performed through the full range in a supported position, yet cannot overcome gravity on its own. The other statements describe stronger or weaker levels: moving through the full range against gravity with no resistance is stronger, a trace contraction with no movement is a minimal contraction, and normal strength is full power against resistance.
