Polio & PPS Flashcards
what is polio
a virus that selectively attacks motor neuron cell bodies with resulting flaccid muscle paresis or paralysis
what are the four methods of return to function in muscles impacted by Polio
sprouting, hypertrophy of innervated fibers, neuronal adaptation, or compensation
what are giant motor units?
the result of recovered neurons developing terminal axon sprouts to re-innervate orphaned muscles
nerves that serve fine motor function have a low ratio or high ratio of nerve to fiber?
low ratio; conversely, postural muscles have a high ratio of fibers innervated by a single nerve
what is the biggest polio/PPD tenant for exercise
patients with 4/5 or 5/5 MMT would react positively and strengthen in response to exercise, but those with 2-3/5 MMT would get weaker with exercise
symptoms of PPS
profound fatigue, muscle and joint pain, new weakness/functional weakness
etiology of PPS
unknown, but no evidence that says the virus has been reactivated.
what can we do as PTs for PPS
educate on pacing/energy conservation, orthotic assessment, orthopedic stuff
Sit to stand is an upper or lower initiated trunk movement?
LOWER!
how does early understanding of PPS impact rehab?
upon polio dx, patients worked very hard in rehab with strenuous exercise to regain motor function, but this is not the treatment choice in PPS so patients are being told the opposite of what they remember
what type of training is safe and effective for PPS patients
sub-max resistance and endurance training
should patients be fatigued when they finish exercise interventions with PPS
no - avoid exhaustion with PPS population
