7
Q
what is the main scale used for assessment of spasticity?
A
- modified Ashworth scale
8
Q
what is the MAS scores meaning?
A
0= no increase in muscle tone
1= slight increase in tone, manifested by catch and release at the end of ROM
1+= slight increase in tone, manifested by a catch, followed by minimal resistance throughout the remainder of range
2= marked increase in tone throughout most of range, still easily moved
3= considerable increase in tone, passive movement difficult
4= affects part(s) rigid in flexion/ extension
9
Q
how do you test spasticity?
A
- inner to outer range
- assess slowly at first to assess PROM available
- then move limb more quickly to assess spasticity
10

11
Q
what does the MTS involve?
A

12
Q
what does R1 and R2 represent in the MTS?
A
R1= angle of muscle response (catch) as joint is moved at the fastest velocity possible
R2= angle of muscle response (end range) at the slowest velocity possible
13
Q
what does the difference between R1 and R2 indicate? what does a large difference show?
A
- difference between R1 and R2 indicates the relative contribution of spasticity versus contracture
- large difference shows more spasticity whereas small difference shows contracture

29
what should you discuss with the patient before treating spasticity? what should you explain?
- discuss the balance between the benefits and harms of treating spasticity
- explain that some people use their spasticity to maintain their posture and ability to stand, walk or transfer in which muscle relaxants will adversely affect this
30
what is spasticity useful for and why would you not treat in this case? (2)
- may be useful for function or circulation
31
what is the medication used to treat focal/ multi- focal spasticity?

33
what effect does botulinum toxin have?

what do ankle splints prevent?
- prevents loss of ROM at the ankle when positioning at PG (for people with stroke)
69
should splints be used for the upper limb?
