Grades of Muscle Strength

Grade                     Description

N = normal; G = good; F = fair; P = poor; T = trace

5 or N           Full range of motion against gravity and full resistance for the patient's size, age, and sex

N−               Slight weakness

G+               Moderate weakness

4 or G           Movement against gravity and moderate resistance at least 10 times without fatigue

F+               Movement against gravity several times or mild resistance one time

3 or F           Full range against gravity

F−               Movement against gravity and complete range of motion one time

P+               Full range of motion with gravity eliminated but some resistance applied

2 or P           Full range of motion with gravity eliminated

P−               Incomplete range of motion with gravity eliminated

1 or T           Evidence of contraction (visible or palpable) but no joint movement

0                No palpable or visible contraction and no joint movement
