Q

explain the “Inside-out model” theory of MS

A

Q

explain dissemination in space and time

A

dissemination in space:

scotoma
marcus Gunn Pupil
nystagmus
diplopia

24
Q

marcus Gunn Pupil

A

shine light in eye and both eyes dilute

25
what is the biggest issue that 95% of pts experience on a daily basis that doesn't relate to severity of disease
fatigue
26
name exacerbating risks that cause fatigue 5
mood (depression) spasticity exertion heat not enough sleep
27
what are the 3 Ds pt experience if the cerebellum is involved
dysmetria dyssenergia dysdiadochokinesia
28
pt with MS present can present with what kind of tremor?
intentional (mvmt) tremor
29
fear of falling is associated w. self-imposed restriction in mobility leading to
inc disability/falls & social isolation
30
T/F 50% of RRMS will req. AD w/in 15 years
T
31
what are the for 3 Ds of speech that 40% of pt exibit?
dysphagia dysphonia dysarthria
32
T/F ~80% of pts have issues with bowel, bladder, and sexual dysfunction
T
33
life expectancy after diagnosis of MS?
25yrs
34
what are the predictors of good prognosis of MS?
1. onset w. only 1 symptom 2. benign & RRMS 3. <40yo 4. neuro imaging at 5 years with few overall lesions
35
T/F no medications can reverse existing deficits
T
36
what are the 3 functions of meds?
1. management of acute relapse via corticosteroids 2. disease modifying agent via synthetic interferon 3. management of symptoms
37
explain the 3 kinds of preventions primary, secondary, tertiary
Primary: prevent MS and HTN Secondary: meds to delay or for symptoms management Tertiary: minimize deg of of disability
38
preventive & restorative techniques during early-moderate stage of MS
regular exercise to improve strength, ROM, balance Community classes to maintain social life + positive outlook
39
compensatory strategies in middle-mod stage
AD to maintain function W/c for community ambulation
40
In late to advanced stages of MS are pts able to live alone without any assistance?
no. they're unable to live alone, req full time assist, and are dependent w. most ADLs
41
preventive interventions in late-advanced stages MS
maximize upright posture & out-of bed time while preventing contractures, pneumonia, & wounds
42
compensatory strategies in late-advanced stages
family education on positioning , pressure relief devices + psych support
43
T/F utilizing vibration with tuning fork aids in balance performance
T?
44
what outcome measure do you use to assess fatigue in MS?
VAS for fatigue, fatigue scale for motor & cognitive functions (FSMC)
45
20 question pt reported outcome Assess affects of cognitive and motor fatigue in their daily life 20-100 point scale
Fatigue scale for motor & cognitive functions (FSMC) ≥43 is mild fatigue ≥53 is moderate fatigue ≥63 as severe fatigue.
46
(self-report impact of MS on walking ability) 12 diff questions about walking and if MS does not affect or extremely affects their ability helps keep track of MS and what exactly is causing issues
12-item MS Walking Scale Higher scores indicate a greater impact on walking than lower scores. out of 60points and turned to percentage
47
Self reported measure (emotional, cog, function) asks how they feel compared to ~4wks ago, whats bothering them the most which helps determine if referral is needed
Multiple Sclerosis Quality Of Life—54 (MSQOL-54)
48
what do you always have to keep in mind when treating an MS patient (environment)
keep in mind heat, temp to prevent overheating cause can cause exacerbation
49
Pt's (should/should not) exercise during exacerbation
Should not, wait until remission
50
T/F You should monitor fatigue, spasticity, balance, tremor, heat tolerance
T
51
Eccentrics and BFRT should be utilized when working on?
gait
52
what 2 orthotics would MS pts benefit from
articulating AFO to promote DF or posterior leaf AFO
53
should MS pt do resistance training every day or on alternate days?
alternate to prevent fatigue/overwork
54
do pts with MS have increased spasticity and decline in cog function?
yes
55
when do pts with MS present w. autonomic dysfunction?
advanced stages
