Week 4 Flashcards
What changes with neuroplasticity in short-term?
Synaptic, actional potential and target cell
What changes with neuroplasticity in long-term?
Structural and functional - connections increase, axons grow
What is potentiation in relation to neuroplasticity?
High response of activity/learning creates short-term to long-term changes in the brain
What is depression in relation to neuroplasticity?
Low response of activity/learning you will slowly lose over time the less you use/learn it.
What does long-term neuroplasticity depend on?
- Practice
- Repetition
- Intensity
- Challenge - need to struggle
Doing things that are mentally stimulating and hold attention
* Meaningful
* Motivation
* Rewarding
Neuroplasticity & skill acquisition
- Restore – original neural pathways
- Re-wire the brain – function previously managed by a damaged area can be taken over by an undamaged area
- Response to training and experience – the primary driver of change is behaviour i.e. what our patients do all day
- Experiences to the CNS come in different forms – movement/activity and thought
- Neuroplasticity can be positive or negative
What is constraint-induced movement therapy?
Patient has weakness in left hand, therefore taking the right hand out of the equation makes them use their left hand.
What is top-down in relation to neuroplasticity?
Attention holding during a task
What is bottom-up in relation to neuroplasticity?
Repetitive practise of a task
4 core IRIS principles of neuroplasticity when implementing in practice
Importance - things need to be important to us for motivation
Repetition - 1000’s for neuroplasticity
Intensity - it needs to be hard, no pain no gain, physically and cognitively
Specificity - specific to each client
Individual resources required for balance - biomechanical constraints
- Degrees of freedom
- Strength
- Limits of stability
Individual resources required for balance - Movement strategies
- Reactive - feedback from environment
- Anticipatory - feedforward from memory
- Voluntary
Individual resources required for balance - sensory strategies
- Sensory integration
- Sensory reweighting (looking in dark, less visual, more vestibular/proprioception)
Individual resources required for balance - orientation in space
- Perception
- Verticality
Individual resources required for balance - Cognitive processing
- Attention
- Learning
What types of compensatory strategies are their with balance?
Typical and atypical
Why is moving around on the floor a skill to teach?
People who are at risk of falls
Important for full range of life activities e.g., playing with kids, gardening
