what part of motor control can a therapist impact?
action and perception
define motor learning
set of processes associated with practice that lead to changes in skilled movement
what are the three stages in motor learning according to fitts and posner?
cognitive - step by step
associative - refinement
autonomous - mastery, takes no thought
where learner focuses attention
what are the three stages in motor learning according to bernstein?
establishing - freezing degrees of freedom
refining - reorganizing
exploiting - mechanics and inertia
focus of degrees of freedom
closed loop theory
trial and error
perceived correctness
same exact skill
schema theory
outcome
variety of practice
emphasize result
cognitive theory
best with low cognitive demand
need cognitive demand as they progress
hierarchical
revert to processing step by step when under stress
optimal theory
motivation helps learn quicker
verbal preparation
over explanation hinders learning
focus on what to do
auditory cues
visual prep
watching a new movement aids motor learning
observing mistakes and correction helps most
mental prep
mental practice aids learning, but physical practice is usually preferable
focus prep
an external focus is preferable to an internal focus
external = intended body movement
distance of focus should correspond to proficiency
motivation prep
learn better with high self-efficacy
give choices
link to pt goals
positive feedback
distribution
rest breaks improve performance and learning
variability
high open-task performance
high learning
good for children
contextual interference
improves learning and transfer
knowledge of performance
dependent on focus
guidance boosts performance
best suited for:
new learners
slow movements
complex tasks
tasks that may injure or fear
knowledge of results
preferable
helps to a point
fade out for optimal learning
deliver after a slight delay
2-15 trials
optimal feedback
autonomy
enhanced expectations - positive best
feedback allows redirection
effleurage
broad strokes
hand in shape of the limb
warm up the tissue
petrissage
kneading - increases circulation, mobilizes
rolling - perpendicular to muscle fibers
cross friction massage
for tendons
prevent adhesions
must be on target tissue
perpendicular
passive stretching

lengthens affected tissue
hold 15-30 seconds, release, repeat
2-4 reps
