Q

Many patients with MS take meds for spasticity, what is an important side effect of these meds?

A

An important side effect of spasticity meds is fatigue.

So, its important for a PT to know dosage and when meds were taken

Q

An article by Hebert “The Ass’n between MS-related fatigue and balance as a function of central sensory integration” looked at what conditions?

A

Computerized dynamic posturography: sensory organization test (SOT)

1) Eyes Open - no sway reference
2) Eyes Closed - no sway reference
3) Eyes Open - visual/surround sway reference
4) Eyes Open - support surface sway reference
5) Eyes Closed - support surface sway reference
6) Eyes Open - visual/surround and support surface sway reference

Found there was a high correlation with fatigue.

A
  • Supratentorial brain structures
    1) perventricular
    2) corpus collosum
    3) optic nerves
  • Spinal cord
  • Infratentorial brain structures
    1) cerebellum (cerebellar peduncles)
    2) brainstem

Q

Describe VOR

A

VOR - visual fixation during head movement; vestibulo-ocular reflex; stabilizes images during head movement by producing an eye movement in direction opposite to head movement - preserving the image on the center of the visual field.

  • Tracking (smooth pursuit & VOR cancelation (overshooting the target))
  • Saccadic eye movements
  • Convergence/Divergence

Q

What is the BEEMS program?

A

BEEMS: Balance & Eye Movement Exercises for persons with MS

Eye movements: eye movements, visual fixation

Balance: varied feet alignment, varied compliance of standing surface, varied visual input, head movements, multi-tasking, “on command” walking tasks

17
Q

What is an example of multi-directional compliant surface? Of multi-directional responsive surface?

A

Multi-directional compliant surface - foam

Multi-directional responsive surface - trampoline (uses up a lot of energy, surface won’t allow large motions)

18
Q

What are 2 types of CNS repair and reorganization?

A

1) Neural repair (axonal and dendritic collateral sprouting, axonal regeneration, &/or neurogenesis)
2) Circumduct pathological neural pathways (neural adaptation & recruitment of parallel neural pathways that are able to control the same motor units)

19
Q

What are the “X-factors” for MS?

A

1) Impaired balance
2) Dizziness
3) Fatigue

20
Q

Where should falls be classified? Activity; Body, structure, & function; or Participation?

A

Participation restriction - determine if they are due to impaired balance and which system is affected

21
Q

T/F - Transient associated with relapse; non-fatiguing positional vertigo is tested with Dix-Hallpike

A

False!

Transient associated with relapse/non-fatiguing positional vertigo is consistent with lesion involvement of CN VIII &/or vestibular nucleus. Test for BPPV is not required.

Chronic recurring episodes/fatiguing positional vertigo is consistent with BPPV and is tested with Dix-Hallpike

22
Q

What test is used to assess the disability level of a patient with MS?

A

The Expanded Disability Status Scale (EDSS)

23
Q

What levels of the EDSS will benefit most from MS physical therapy?

A

0-6.5 benefit most (per my notes listening)

The box is around 0-6.0, but it doesn’t say what that means.

24
Q

Describe the EDSS disability levels.

When is an AD needed?

A

0-2.5 = None to minimal

  1. 0-4.5 = fully ambulatory without aid
  2. 0-5.5 = limited ambulation without aid
  3. 0 = Intermittent or unilateral aid for 100m
  4. 5 = Constant BIL aid for 20m
  5. 0-10.0 = Extreme limits or absent ambulation
25
What tests are done for VOR?
1) Gaze stabilization test (GST) (establishes speed of mead motion with fixation) 2) Dynamic visual acuity test (DVAT) (establishes acuity/fixation at constant speed of head motion); uses snelling chart; abnormal if visual acuity is above 3 lines of static acuity line
26
What 4 conditions of the mCTSIB are used for patients with MS?
1) eyes open, firm surface 2) eyes closed, firm surface 3) eyes open, foam surface 4) eyes closed, foam surface 3 trials each, up to 30 seconds; validated in other populations such as older adults
27
Top clinical tests to perform for a patient with MS.
1) DGI (cutoff 19; sens 87%, spec 51%) or (cutoff 12; sens 45%, spec 80%) 2) Berg balance scale (cutoff 44; sens 40%, spec 90%) 3) Self-report: Activities-specific Balance Confidence (ABC) (cutoff 40; sens 65%, spec 77%) 4) Self-report: Dizziness Handicap Inventory (DHI) (cutoff 59; sens 50%, spec 74%) 5) Self-report: Modified Fatigue Impact Scale (MFIS) (cutoff 38); The MFIS correlates with walking capacity and disability - minimal detectable change (16.2 or 20.2)
28
Which of the 2 tests when combined are best at discriminating falls?
1) ABC | 2) DHI
29
For a patient with MS, what are MS-specific important factors to consider?
1) Pyramidal function (strength/motor force production; tone/spasticity) 2) Cognition (attn to task; memory) 3) Psycho-social 4) Depression 5) Monocular or binocular loss of vision
