Week 4.2 Interventions for weakness 1

Question 1

TF: there is strong evidence and support for efficacy of strength training in people with neurological disorders

Answer 1

true

Question 2

strength training can do what to the cortex

Answer 2

increase cortical excitability

Question 3

why are there fewer motor neurons areas activated after training

Answer 3

because of inhaled efficacy of synapses

Question 4

what does strengthening do to motor unit recruitment and neural drive

Answer 4

increases in neural drive, and changes in recruitment

Question 5

TF: strengthening does not improve motor unit recruitment

Answer 5

false, it does

Question 6

do we want longer or shorter treatments

Answer 6

longer

Question 7

how can we customize a strengthening intervention

Answer 7

by making it fit the characteristics of the patient, like age, co-morbidities, functional level, balance ability, stage of disease.

Question 8

why is it important to have ongoing evaluation and progression

Answer 8

we need continual challenge to the neuromuscular system to adapt and facilitate optimal recovery

Question 9

what is 5D. what will improve function

Answer 9

non progressive disorders of the CNS, specifically related to site and severity of the BI. correlates with functional status, and remediation will improve function

Question 10

what is 5E

Answer 10

progressive disorder of the CNS, with a progressive decline with strength. So MS, PD, ALS

Question 11

what is 5G

Answer 11

acute or chronic polyneuropathies like GBS, so be careful with recovery phase not to over fatigue

Question 12

what is 5H

Answer 12

non progressive disorders of the SC. weakness or total paralysis, like SCI. so the recovery depends on extent of damage, what is spared and neuroplasticity of the SC

Question 13

is the weakness on the ipsilateral or contralateral side of the lesion

Answer 13

contralateral side, although I guess there is weakness on the ipsilateral side too sometimes because of tracts that are bilateral or do not decussate

Question 14

after a stroke, is flexion or extension affected more

Answer 14

equally

Question 15

what happens to force generation and production after a stroke

Answer 15

generation is reduced, and production is slower

Question 16

what causes decreases in force production after a stroke

Answer 16

central activation deficits, transsynaptic degeneration and secondary changes in the muscles.

Question 17

what is the cause of weakness after an acquired brain injury

Answer 17

central neural activation deficits, impaired ability to active MU

Question 18

Is it common for people who have acquired BI to have disuse atrophy

Answer 18

yes

Question 19

what happens to axons and nerve conduction in MS

Answer 19

axon degeneration and reduced or blocked nerve conduction

Question 20

what happens to force production in MS

Answer 20

reduced and slow
