Neuroplastic Principles Flashcards
(28 cards)
Define dosage
Training of more than 5 hours a week
Definition of structured practice
Training schedule with frequent and longer breaks
Definition of task-specific practice
Movements preformed relevant for ADL and goal oriented
Definition of variable practice
Several tasks require different movements
Definition of multi sensory stimulation
Providing feedback through multiple senses
Definition of explicit feedback
Knowledge of RESULTS
Definition of implicit feedback
Knowledge about performance
What is compensation
Learning new methods to perform tasks
What is the process of restoration
Neuroplasticity
What are 5 principles of effective training
-specificity
-intensity
-time
-salience
-rep
What are 3 types of neuroplasticity
Experience expectant
Experience induced
Long term potentiation
What is experience expectant NP
Based on experience
-norm development
What is experience induced NP
After neuro injury
-motor learning, skilled motor act, skill adaptation
What is long term potentiation? What does it increase? Key to what?
Occurs at cellular level, constant process
Presynaptic NT’s and postsynaptic receptors
Permanent change
Role of ex in neuro genesis
Aerobic and resistance induces hippocampal neuro genesis
-increase cerebral BF, and memory
What is time/dosage for adult neuro injury (CVA)
-wait 24 hours if med stable
-sm frequent doses
-ex 2-3 m’s post CVA
- > 3 hrs better outcomes
Motor learning creates connections to what part of the brain
Striatum — BG
What does strength training increase
Increase spinal motor neuron excitability
Rats showed greater # of what regarding strength
Excitatory synapses
How does co-contraction activities affect IA
Decreased Ia transmission, SC
What is multimodal stimulation? What type of info can be incorporated
> 1 sensory or motor act targets brain activity
Auditory and visual
What part of the brain is involved with attention, motivation, and vision
Frontal, BG, occipital
What part of the brain is involved with goal orientation
Premotor cortex
Aerobic ex affects what part of the brain? Influences what?
Frontal lobe
Executive function
