Muscle strength and sensory grading

Muscle function grading	Sensory grading
0 = total paralysis	0 = Absent (or inability to tell sharp from dull)
1 = palpable or visible contraction	1 = Altered, either decreased or impaired sensation or hypersensitivity
2 = active movement, full ROM with gravity eliminated	2 = Normal
3 = active movement, full ROM against gravity	NT = Not testable
4 = active movement, full ROM against gravity and moderate resistance in a muscle specific position
5 = (normal) active movement, full ROM against gravity and full resistance in a functional muscle position expected from an otherwise unimpaired person 5* = (normal) active movement, full ROM against gravity and sufficient resistance to be considered normal if identified inhibiting factors (ie, pain, disuse) were not present
NT = not testable (ie, attributable to immobilization, severe pain such that the patient cannot be graded, amputation of limb, or contracture greater than 50% of the normal ROM)
