Manual Muscle Testing (MMT).

Score	Muscular strength	Muscle activity
0	Zero	No evidence of contractility; total paralysis
1	Trace	Evidence of slight contractility (no joint motion); palpable or visiblecontraction
2	Poor	Active movement; full range of motion with gravity eliminated
3	Fair	Active movement; full range of motion against gravity
4	Good	Active movement; complete range of motion against gravity and moderate resistance in a muscle-specific position
5	Normal	Complete range of motion against gravity with full resistance in a functional muscle position expected from an otherwise unimpaired person
