What does muscle score 1 indicate?

Explanation:
This question tests how muscle strength is graded on the standard scale. A score of one means there is a trace contraction: you can feel or see a tiny, faint contraction when the patient attempts to activate the muscle, but it is not enough to produce any movement at the joint. In other words, there’s detectable muscular activity without actual joint motion. This distinguishes it from zero (no contraction) and from higher grades where movement against gravity or against resistance is possible.
