Spasticity Scales.

Grade	Spasticity Scale			Deep Tendon Reflexes
	Modified Tardieu Scale	Modified Ashworth Scale	Penn Spasm Frequency Scale
0	No resistance throughout the course of passive movement	No increase in tone	No spontaneous spasms	1+	Hyporeflexic response
1	Slight resistance through the course of passive movement, with no clear catch	Slight increase in tone, manifested by a catch and release or minimal resistance at end range of motion	No spontaneous spasms; spasms with rigorous sensory or motor stimulation	2+	Normal reflex response
2	Clear catch interrupting the passive movement, followed by a release	Marked increase in tone, manifested by a catch at mid-range of motion and resistance throughout remainder of motion	Occasional spontaneous spasms and easy induced spasms	3+	Brisk reflex response—no clonus elicited
3	Fatigable clonus (<10 s) while maintaining pressure	Considerable increase in muscle tone, with passive movement difficult	>1 but <10 spontaneous spams in an hour	4+	Brisk reflex response with associated clonus
4	Infatiguable clonus (>10 s) while maintaining pressure	Affect part rigid and fixed in place	>10 spontaneous spasms in an hour
