Neurointerventions Flashcards
why can we make changes so quickly following an injury?
because the CNS is not hardwired
what occurs during recovery of function?
neuroplasticity
resolution of prenumbra
subsequent spontaneous recovery
how long does subsequent spontaneous recovery go on for?
3-6 months
how does plasticity occur as a result of injury?
functional reorganization of the cortex maps
3 synaptic changes that follow after injury
reduction of swelling
axonal sprouting
receipt of neurotransmitter from adjacent sites
unmasking
what interventions promote neural reorganization?
functional task training:
CIMT, robot assistive therapy, repetitive task training, arm ability training, circuit training for UE and LE
functional reorganization is….
skill and motor learning dependent rather than use dependent
brunnstrom stags can be used as a measure of…
progress
in behaviorist or cognitive theory…
environment drives motor development
what model lead to brunnstrom and NDT?
hierarchial
what are the three tenents of neuronal group selection theory.
basic connections, trial and error, expansion
theories that show how the CNS and PNS control action?
open loop and closed loop
techniques used for NDT
handling
weightbearing over affected limb
utilize positions that allow use of affected limbs
avoidance of sensory input that affect muscle tone
evidence on bobath?
limited
what type of muscle patterns that occur which are spiral and diagonal in nature?
mass, PNF
type of approach PNF takes
multi sensory approach
effectiveness of PNF
PNF
is PNF better as an adjunct?
yes
evidence on PNF
sparse and inconclusive
evidence on brunnstrom
limited
describe brunnstrom
reflexive/primitive/automatic -> volitional
basic principles of rood
normalized tone is prereq to movement
flexion and extension patterns affect one another
movement is directed towards functional goals
repitition
necessary for motor learning
limitations of rood approach
passive in nature
no evidence
short lasting
low level brain injury pts benefit from…
rood approach
4 variables affecting motor learning
stages of learning
sensory conditions
feedback
practice schedule
what is an impt factor in reinforcing motor skill acquisition
feedback
how is skill demonstrated?
after a time delay to measure retention
who benefits from distributed practice?
apraxia
