Medical Research Council (MRC) Scale for Muscle Strength

EFFORT 0-5 SCALE
Muscle contracts against full resistance 5
Strength reduced, but contraction can still move joint against resistance 4
Strength further reduced such that joint can be moved only against gravity with examiner's resistance completely removed. 3
Muscle can onlly move if resistance of gravity is removed. 2
Only a trace or flicker of movement is seen or felt, or fasciculations are observed, 1
No movement 0
