Q

Avg age of clinical onset is 30–33 years of age…but the avg age of
diagnosis is 37… why is there such a delay

A

because

1) symptoms come and go
2) MS gets mixed up with other conditions
3) symtpoms may vary person to person

Q

In 1936, only 8% of patients were reported to survive beyond 20 years
after onset of illness… but a patient can now expect to live the average
population life-expectancy minus seven years… why such a change

A

better treatment and drugs
better knownldege
and MAYBE better nutirition

39
Q

true or false: the symptoms of MS are the same for everyone

A

May differ greatly from person to person and over the course of
the disease depending on the MS type and location of the lesions
within the nervous system:

40
Q

if you have an optic nerve lesion what are the signs and symptoms

A

blurred vision

41

A

dizzinesss AND MAYBE double vision

42
Q

if you have a cerebellum and cerebrum lesion what are the signs and symptoms

A

balance problems, sppech problems, uncoordinated movements and tremors

43

if you have a motor nerve tract lesion what are the signs and symptoms

A

muscle weakness, spasticity paralysis, bladder and bowel impairments

44

if you have a sensory nerve tract lesion what are the signs and symptoms

A

altered sensation, numbness, pricking, and burning sensation

45
Q

what lesion causes blurred vision

A

brainstem

47
Q

what lesion causes balance problems, speech problems,
uncoordinated movements and
tremors

A

cerebellum and cerebrum

Q

what lesion causes muscle weakness, spasticity paralysis,

bladder and bowel impairments

A

motor nerve tract lesion

49

50
Q

what symtpom is common in 78% of all patients

A

fatigue

51
Q

fatigue is common in what percentage of patients with MS

A

78

52
Q

what are the 2 mojor symtpsoms of MS

A

fatigue

tremor, lack of coordinationn, unstead gait

53
Q

when there is a MS flare up what happens to the myelin

A

it becomes inflammed

54
Q

if there is scar formation after the myelin sheath becomes inflammed, what happens

A

permentant myelin damage and loss of function

55
Q

if there is no scar formation after the myelin sheath becomes inflammed, what happens

A

complete recoverey and no loss of funciton

56
Q

what can disease modifying therapies help with.

A

decrease the severity and help against he frequency of relatpses

57
Q

MS classification is based on what two things

A

1) rate of disease progression

2) frequence of flare ups

58
Q

what are the 4 types of MS

A
relapsing/remitting MS (RRMS)
Secondary progressive MS (SPMS)
Primary progressive MS
(PPMS)
Progressive relapsing MS
(PRMS)
59
Q

what is the most common type of MS

A

relapsing/remitting MS

60
Q

explain Relapsing Remitting MS

A
Unpredictable but clearly defined
relapses (also known as attacks,
exacerbations or flare-ups) during
which new symptoms appear or
existing ones get worse
61
Q

true or false, in the period between relapses in relapsing MS, how is recovery

A

recovery is complete or near complete to prelapse function (remission)

62
Q

what is more severe: relapsing MS or secondary progressive MS

A

secondary progressie

63
Q

epxlain secondary progressive MS

A

Follows a diagnosis of RRMS. Over time, distinct relapses and remissions become less apparent and the disease begins to progress steadily (figure 2a), sometimes with plateaus

64
Q

about half of people with relapsing MS start to worsen within what years and what does that come with

A

within 10-20 years of dianosis and that comes with increase levls of disability

65
Q

true or false: meds can helo RRMS

A

true

66
Q

True or fals: meds can help SPMS

A

true

67
Q

which type of MS is a slow accumulattion of disability without defined relapses

A

Primary progressive MS. (PPMS)

68
Q

PPMS has defined or undefined relapses

A

no defined relapses

69
Q

true or false. in PPMS there are periods of remission and explain

A

false it May stabilize for periods of time, and even offer minor temporary improvement (figure 3b) but
overall, there are no periods ofremission. A

70
Q

what is the percentage of people with MS have primary progressive multiple scleoris

A

10 per
cent of people diagnosed with MS
have PPMS

71
Q

what is the ratrest course of MS

A

progressive relapsing MS

72
Q

what is the incidence of progressive relapsing MS

A

5%

73
Q

explain progressive relatpsing MS

A
People with this form of MS
experience relapses with (figure 4a)
or without (figure 4b) recovery and
steadily worsening disease from the
beginning
74
Q

true or false: meds cannot help with progressive relapsing MS

A

false they can

75
Q

what is the only type of MS thaat cannot be helped by meds

A

primary progressie

76
Q

can people with MS treain

A

yes

77
Q

can exercise be harmful to MS

A

yes it can trigger flare upa

78
Q

are kceps qualified to train clients with MS

A

yes

79
Q

what does meeting the PA guidelines do for thsoe with MS

A

reduce fatigue
improve mobility
enhance elements of health related quality of life

80
Q

who are the PA guidelines for in MS

A

for adults with minimal to moderate disability resulting from either relaptsing/remitting MS or progressive forms of MS

81
Q

true or false: those with MS should consult a HC professional before behining

A

true

82
Q

if you are a physically inactive person with MS how should PA be performed

A

true q

84

85
Q

how often should those with MS perform areobic and strength training

A

two times a wee

86
Q

what is the time someone with MS should do aerobic exercise

A

at least 30 minutes durinng the workout session

87
Q

what is the ampunt of sets and reps someone with MS should do in RT

A

2 sets of 10-15 reps

88
Q

how hard/intensity should aerobic exercise be for those with MS

A

moderate intensity PA (5/6 on scale of 10) and causes HR to increase
you should be able to talk but not sing a song during the actitvty

89
Q

what should the inteisty be for RT for those with MS

A

pick a resistance (free wights, pulleys bands etc) that is heavy enough to barely, but safely, finish 10-15 reps of the last set

90
Q

what are some good aerobic activites for those with MS

A

upper body exercises: arm cycling

lower body exerceises: walking, leg cycling

combined: eliptical

=aquatic

91
Q

what are some good strength training activties for those with MS

A

weight machines
free wights
cable pulleys.

92
Q

whart are the special consideration to exrcise with MS (5)

A

lower level of fitness (cardio, muscle endurance and strenght and balance)

fatigue

heatt intolerace

depression

exercise does not trigger flare ups with properly managed

93
Q

true or false and explain: those with MS have heat intolerance

A

true they have a body temp 0.5 higher

94
Q

what are the 4 effects of exercise on MS

A

1) increases aerobic capacity
2) increases muscular sttrength and endurace
3) increase QOL
4) increase independace in ADLS
