Medical research council scale

Medical Research Council (MRC)> muscle strength scale
0	No observable muscle contraction or movement.
1	Muscle contraction is evident, but there is no joint movement.
2	Muscles can move the joint when gravity is removed (passive movement).
3	Muscles can move the joint against gravity but not against additional resistance.
4	Muscles can move the joint against some resistance but are weaker than usual.
5	Normal muscle strength, enabling the joint to move against full resistance.
