STROKE Flashcards
Strategies to train weak muscles (<2/5)
Strategies to train weak muscles: Grade 0-2
Grade 0-1 /5: ES
Grade 2-/5: EMG biofeedback
Reduce friction → socks, skateboard, slidesheet
Eliminate gravity → change position
Shorten lever
Provide manual guidance
Reduce degrees of freedom
Mental practice
List and describe 8 factors that influence neuroplasticity
(URTTEAPP)
- Use-dependent and specific
- Repetition and intensity
- Time-sensitive
- Task performance, motivation, feedback and attention
- Environmental features
- Adjuvant or adjunct therapies
- Patient characteristics
- Pharmacology
What are the 3 practice variables that influence motor skill acquisition?
- Practice intensity (high reps)
- Practice specificity (whole/part task)
- Practice variability (less then progress)
what is meant by practice intensity for stroke patients
neuroplasticity can take days, weeks, months..
Lots of reps are required for motor skill acquisition.
What strategies can you use to increase the amount of practice for practice intensity?
group therapy
training partner
incorporate training into daily living
exercise booklets
independent and semi-independent supervised practice.
What is meant by practice specificity in motor skill acquisition?
Movements should be similar and in the correct context while the skill is being practiced.
Use whole and part task practice to best replicate the skill that is being practiced.
what is meant by practice variability in motor skill acquisition?
The variability in movement and context characteristics the learner experiences when practicing a skill.
How can we make a skill more specific?
Senses: vision, proprioception (walk on uneven terrain), attentional (count steps out loud) and cognitive (multi-tasking)
Muscles: joint angle, muscle length, type and velocity of contraction, open or closed chain
Environment specific: objects, equipment, active, static.
How can we make a skill more variable?
Additional tasks/ skills/actions
Intertrial variability
Contextual interference (sequencing, i.e. low = blocks of the same skill practice, high = random order of trials between task variations)
WALKING example:
- Change the surface, alter the speed, change the environment (inside v outside), include obstacles, change footwear, add dual task.
Outline factors that increase the difficulty of training
Task:
- increase reps, frequency, duration.
- increase resistance
- reduce manual guidance
- increase speed, distance, amplitude
- progress from part to whole task
- add a cognitive task
Environmental:
- reduce base of support
- change support i.e. soft chair
- increase attentional demands
- change the environment
- perform in a loud/busy space
What are important considerations when providing instructions to patients?
Timing (before, during or after)
Type (sentence length)
Frequency (attentional capacity of the patient)
difference between knowledge of results and knowledge of performance?
Knowledge of results provides info about the outcome of a result
Knowledge of performance gives feedback on the process of performing a skill
how can qualitative feedback be helpful in rehab
can provide improvements in technique
In what scenario would you prefer intrinsic feedback over extrinsic feedback?
when patients are skilled enough to evaluate their own performance
