CIMT Flashcards
What is neuroplasticity?
It’s the brain’s ability to reorganize and form new neural connections
- it responds to training and practice to compensate for an injury or disease
What is motor skill learning dependent on to make changes in the motor cortex?
An enriched environment with intensive motor training to help regain the motor control
What is the theory of learned non-use for early CVA?
Stroke pts try to use their affected limb = reinforces the use of the affected limb
happens into the chronic stage to keep the training going
What are the proposed mechanism of CIMT?
taking away learned non-use
using dependent cortical reorganization
Why does CIMT want to take away learned non-use?
constricting encourages the use of the affect limb thru conditioning
What is the premise of cortical reorganization?
repeated and sustained practice = increased cortical representation of the involved UE
What is the premise of learned non-use theory?
a low sudden hand use and poor functional ability is because:
- suppression of the ability because of sub-acute conditioning and learning compensation with the unaffected hand
= dimished cortical limb representation because of the theory (!!)
What is the premise behind CIMT?
increased spontaneous hand use and better functional ability through:
- increased motivation and specific task practice
= altered cortical limb representation because of increased use
What is the traditional programing for CIMT?
patients will participate in:
- 4-6 hrs
- 5x a week
- 2-3 weeks
What is the programing for the UE for CIMT?
they’ll weak a mitt on the uninvolved UE for 90% that they are awake for 2-3 weeks
What is the programing for the LE for CIMT?
NO constraints but activities are focused on reliance on the involve LE
What is the frequency of the modified program CIMT?
1-2 hours of PT and OT
3-5x a day over 3-4 weeks
What is the programing for modified program CIMT?
focuses on CIMT activies
BUT
mitts only for 5-6 hours during waking hours
What are the elements of CIMT?
- intensive task-oriented training
- behavioral strategies
- restriction of the uninvolved extremity
What are the components of task practice?
tasks are functionally relevant
global feedback
task is challenging
with contextually appropriate tasks
What is the purpose of global feedback for the patient?
PT gives feed given the overall performance
Why is it important to have challenging tasks in regard pt improvement?
variety and difficulty is needed to regain movement control
What is the frequency regarding functionally relevant tasks?
done continously for 15-30 minutes
- tasks like grooming, setting the table, etc.
What is shaping?
reps of a specific movements ina series of trials
- also known as adapted task practice
How is functional activities practiced in regards to shaping?
practiced for a set of 10 timed trials
- explicit feedback from PT in regard to performance in each trial
