Cards

Term
Motor control
Definition
Area of study dealing with the understanding of the neural, physical, and behavioral spects of movement
Term
Reflex theory
Definition
By sherrington

A stimulus leads to a response sequence of events
Term
Limitations of reflex theory
Definition
1. voluntary movements can be activated without sensory input
2. speed of movements; some so fast that no their is no feedback
3. variety of motor responses to same stimulus
Term
Hierarchial theory
Definition
by Hughlings Jackson

CNS organized into centers:
High-->association cortex
middle-->sensorimotor cortex, basal ganglia, brainstem, cerebellum
low-->spinal cord
Term
Systems theory
Definition
by berstein

cooperative action of many systems
shifting locus of control
coordinative structures simply control
Term
Systems Model
Definition
by vereijken
Novice, advanced and expert learners
Term
Novice learner
Definition
learner simplifies the movement to reduce the degrees of freedom
Term
Advanced learner
Definition
Learner begins to release additional DOF, muscle synergies used to produce coordinated movement
Term
Expert Learner
Definition
Learner has release all DOF, optimizes efficiency of movement
Term
open-loop control system
Definition
absence of peripheral feedback and error detection
Term
Closed-loop control system
Definition
Feedback used to correct movement, can initiate corrections
Term
Motor learning
Definition
A set of internal processes associated with practice or experience leading to relatively permanent changes in the capacity for skilled behavior
Term
Closed-loop theory
Definition
by adams

sensory feedback compared with stored memory of intended movement

Provides reference of correctness and error detection
Term
Schema theory
Definition
by schmidt

slow movements are feedback based whereas fast movements are program based

Schema: rule, concept, or relationship formed on the basis of experience
Term
Recall schema
Definition
used to select, define initial movement conditions
Term
Recognition schema
Definition
Used to evaluate movement responses based on expected sensory consequences/outcomes
Term
stages of motor learning
Definition
by fitts and posner

3 stages: cognitive, associative, and autonomous
Term
Cognitive stage of motor learning
Definition
finding appropriate strategy, overall understanding of skill, cognitive map

"What to do"
Term
Associate stage of motor learning
Definition
refining a movement pattern, use of proprioceptive rather than visual cues

"how to do"
Term
Autonomous stage of motor learning
Definition
skilled at movement, automatic, less attention needed, can perform in changing situations

"How to succeed"
Term
Two stage theory of motor skill acquisition
Definition
by gentile

"getting the idea fo the movement"-understand the goal, develop movement strategies

"Fixation/diversification"- refining movement patterns, adapt to changing task and environment
Term
Knowledge of performance (KP)
Definition
feedback about the quality of movement pattern
Term
Knowledge of results (KR)
Definition
feedback about the end result of outcome
Term
summed feedback
Definition
given after set number of trials
Term
Faded feedback
Definition
given after every trial initially, then progressively less frequently

good for early and later learning
Term
Bandwidth feedback
Definition
given only when performance is outside given error range

Allows for trial and error
Term
delayed feedback
Definition
given after brief delay, allows for self reflection
Term
Massed practice
Definition
rest time less than practice ime

good for high motivation, concentration, and endurance
Term
Distributed practice
Definition
rest time equal or longer than practice time

gives most learning per training time
Term
Blocked practice
Definition
repeated practice in a predictable order, good for early acquisition of skills
Term
Serial practice
Definition
Predictable but non repeating order, good for retentin and generalizability
Term
Random practice
Definition
non-repeating and unpredictable order

good for retention and generalizability
Term
mental practice
Definition
imagine or visualize motor task

when combined with physical practice increases accuracy and efficiency
Term
Transfer of learning
Definition
the gain or loss of task performance as a result of practice or experience on some other task
Term
parts-to-whole transfer
Definition
practicing component parts of a motor activity in order to learn the whole activity
Term
bilateral transfer
Definition
patient practices movement on unaffected side first, then progresses to practice w/ the affected side
Term
regenerative synaptogenesis
Definition
sprouting of injured axons to innervate previously innervated synapses
Term
reactive synaptogenesis
Definition
reclaiming of synaptic sites of injured axon by dendritic fibers from neighboring axons
Term
Diaschisis
Definition
spontaneous recovery due to functional use cortical reorganization
Term
Neurodevelopmental Treatment (NDT)
Definition
by Bobath

postural control is foundation for all skill learning
facilitate normal movements through the use of handling and key poins of control
Term
Motor relearning programme for stroke
Definition
by Carr and Shephard

several basic functional tasks are analyzed and then practiced
Essential assistance use as guidance (i.e. only touch when necessary)
Term
Recovery stages in patients with stroke
Definition
by brunnstrom

6 stages of recovery and patterns of abnormal synergistic control in patients with stroke
Term
Stage 1 stroke recovery
Definition
presence of flaccidity
Term
stage 2 stroke recovery
Definition
emergence of basic limb synergies (abnormal UE and LE patterns)
Term
Stage 3 stroke recovery
Definition
Voluntary performance of all or part of basic limb synergies
Term
Stage 4 stroke recovery
Definition
Beginning of controlled movement outside or synergistic pattern
Term
Stage 5 stroke recovery
Definition
Relative independence of basic limb synergies
Term
Stage 6 stroke recovery
Definition
Isolated, coordinated joint movement
Term
PNF
Definition
by Kabat, Knott & Voss

Functional patterns that are spiral and diagonal
Term
Neuromuscular/Sensory stimulation techniques
Definition
By Rood

Phasic stimuli (quick ice/stretch)
Tonic stimuli
Facilitatory/inhibitory stimuli
Term
Reciprocal innervation
Definition
reflex activation for movement patterns in developmental sequence
Term
Co-innervation
Definition
co-contraction of agonist and antagonist to stabilize body from head to feet
Term
Heavy work
Definition
Movement superimposed on co-contraction
Term
skill
Definition
skilled work, with emphasis on distal portions of body segment
