MS Assessment Flashcards
What happens to action potential and mus
-slow action potential
-impaired control of mus (wk, spasticity)
What causes subsequent energy failure
-mitochondrial genetic variants —> deficient mitochondrial metabolism
2 main things that cause induction of demyelination
Mitochondrial injury and subsequent energy failure
Which nerve fibers are affected in MS
A, b, d
What sensory receptors do alpha fibers have
Proprioceptors
What sensory receptors do beta fibers have
Mechanoreceptors
What sensory receptors do delta fibers have
Temp, pain
What sensory receptor is unaltered
Pain
How is each sensory system disrupted
Equally
What 8 CN would you asses
CN II, III, IV, VI, VIII, IX, V, VII
What are 2 muscular performance descriptions
Flaccid/weakness
What would you find with CN II
Visual field loss, blurred vision
What would you find with CN III and VI
Abnorm horizontal gaze, saccades
What would you find with CN V
Most common, facial numb
What would you find with CN VIII
Vertigo
What structures allow proprioception
MS (length and velocity)
GTO (force production or tension)
What tract has proprioception and vibration
Dorsal column
_________ proprioception to ___________ is from the MS and GTO
Unconscious, cerebellum
What are 4 main characteristics of mus performance
-weakness from plaques
-atrophy
-higher proportion of type 2 fibers
-reduced rate of force development
What are 3 major muscular mechanics that are impaired
-response time
-postural reactions (feedback)
-postural response
What is Lhermitte’s sign
Brief electric shock pain down spine triggered by neck flex
What 4 factors are necessary to accomplish tasks/goals
-force production
-selective control
-biomechs
-sensory
What is the primary cause for falls
Slow conduction speed
When do falls occur
Early, before walking
What is the first demyelination event
Balance impairment
What is the most sensitive and accurate test for balance
Static standing balance
What types of gait do MS pts have
Spastic, ataxia, paretic
