Standard grading scheme recommended for scoring most muscle actions.

Grade	Description
0	No muscle action notable by observation or palpation
1	Muscle action observed but no movement noted
1+	With gravity eliminated, movement observed through < 50% of range
2-	With gravity eliminated, movement observed through > 50% of range
2	With gravity eliminated, movement observed through full range
2+	Against gravity, movement observed through <50% of range
3-	Against gravity, movement observed through >50% of range
3	Against gravity, movement observed through full range and test position held
3+	As 3 but able to hold against minimum break force.
4-	As 3 but able to hold against near moderate break force.
4	As 3 but able to hold against moderate break force.
4+	As 3 but able to hold against near maximum break force.
5	As 3 but able to hold against maxumum break force.
