Lecture 42 - Motor Learning and Neuroplasticity Flashcards
Motor Control
Ability to regulate mechanisms essentail to movement
What are the 3 characteristics of the systems model of motor control
- Individual generates movement to meet demands of specific task performed with a special environment
- Individuals ability to meet demands of task and environment determines their functional capacity
- Movement is a product of interaction between the individual, task and environment
Summary of what will be learning in these flashcards in regards to motor control
What are the 3 individual constrainsts influencing motor control and describe them
- Action: Movement defined in terms of human actions or tasks (understanding of motor output from nervous system to muscles)
- Perception: Transformation of afferen input to psychological meaning information
-Peripheral/Higher-order processing provides interpretation of afferent information
-Sensory system provides information about state of body and features within the enviornment critcial to regulation of movement - Cognition
What are constraints of action
Muscle tone, strength, ROM, co-ordination, balance
What are constraints of perception
Impact registration or integration of sensory info:
-Decreased awareness of body in space
-Visual/touch deficits
What are constraints of cognition
Attention emotion and motivation issues such as:
-Fear of falling
-Ability to focus on environmental stimuli during task execution
-Ability to dual task
T or F: Clients need to develop movement patterns that meet demands of functional tasks while managing motor, perceptual, and cognitive impairments
T
What are 2 ways in which tasks can be grouped
- Functional category
-Bed mobility
-Transfer tasks
-ADL - Critical tasks attributes that regulate difficulty
What are 4 task attributes that regulate difficulty
- Discrete/Continuous Task
-Discrete: Clear beginning and ending (moving sit to stand)
-Continuous: End point is not inherent (eg. walking) - Base support is stable or mobile
-Stable = sitting or standing
-Mobile = walking - Manipulation component: Increases demands for stability (eg. walking while carrying tea)
- Open vs closed task
-Open = People adapt behaviour to constantly changing, unpredictable environment (playing soccer)
-Closed = Little variation and is relatively predictable environment (eg. golf swing)
Understanding attributes of task allows therapist to develop a taxonomy of tasks that provide a framework for
- Assessment
- Progression of training
What are 2 environmental constraints that influence motor control
- Regulatory features: Movements must conform to in environment to complete task (eg. size of cup to pick up
- Non-regulatory features: May affect performance but the movement DO NOT conform to these features (eg. background noise or lighting)
T or F: As therapists we need to prepare our clients to perform in a wide variety of environments. The types of environments may be unique to the client

Motor Learning
Acquisition or modification of movement
What are 4 concepts of motor learning
- Process of acquiring the capability for skilled movement
- Learning results from experience or practice
- Learning cannot be measured directly
- Learning produces relatively permanent changes in behavior’s (short term alterations not considered learning
What are the 3 stages of the Fitts and Posner 3-Stage Model of Learning
- Cognitive stage of learning
- Associative stage of learning
3.Autonomous stage of learning
Cognitive Stage of Learning (Posner) 3 characteristics
Associative Stage of Learning (Posner)
Autonomous Stage of Learning (Posner) 3 characteristics
Learning through the Fitts and Posner Model can be optimized by (4)
- Highly motivated person
- Able to fully attend to task
- Relate and integrate new info to what they already know about task
- Task is meaningful for the person
What are the basic principles of the challenge point theory (motor learning)
Practice is single most important factor for improvements in motor performance (practice is structured to maximize potential for learning)
What 2 factors do basic principle’s of the challenge point theory consider
- Task difficulty
- Skill Level of performer
