Study Notes
Motor Control and Motor Learning
- Motor control is the ability to regulate movement mechanisms. The central nervous system (CNS) coordinates individual muscles and joints into functional movement.
- Sensory information from the environment and body influences movement. Perceptions of self, task, and environment affect movement behavior
- Motor learning involves acquiring and re-acquiring movement and coordination to permanently change performance.
- Balance training practices progressively challenging tasks to facilitate skilled movement.
Movement Emerges From Interactions
- Movement is a result of the interactions between an individual, the task, and the environment.
- Factors within each influence movement organization.
Motor Learning Principles
- Effective motor learning identifies deficits to tailor optimal strategies for performance change.
- Interventions aim to develop sensory, motor, and cognitive strategies in meeting postural control demands.
Key Features of Motor Learning Mechanisms
- Primary Driver: performance-based, external feedback. Utilizes knowledge of performance to assess individual progress.
- Instructive: strategy-based, explicit. Focuses on performance-based strategies during learning.
- Reinforcement: outcome-based, based on success and knowledge of results.
- Use-dependent: task-specific. Repetition for massed practice in achieving motor tasks.
- Sensorimotor Adaptation: recalibration through implicit learning. Prediction errors are addressed during recalibration. Brain regions such as the cerebellum handle sensorimotor adaptation.
Fitts and Posner Theory of Motor Learning
- The theory outlines the stages of learning a new skill: cognitive, associative, and autonomous.
- Cognitive stage involves understanding the activity.
- Associative stage involves refining and improving the effectiveness of skill execution.
- Autonomus stage implies that skills become automatic and require minimal attention.
Motor Learning Stages
- Cognitive stage: understanding the task, developing strategies, evaluating the task. This stage requires high levels of attention, instructions, feedback, and demonstrations.
- Associative stage: refining skills, less variability in performance, slower improvement, days-months of practice depending on individual and intensity.
- Autonomous stage: skills become automatic, minimal attention required, less interference from concurrent tasks.
Motor Learning Influencing Factors
- Verbal Instruction: crucial for learning, and observation of practice are essential.
- Practice Characteristics & Variability: distributed practice with rest improves transfer of learning and prevents fatigue. The total practice time is also a factor. Motivation is crucial.
- Active Participation & Motivation: crucial to maintain engagement and progress.
- Possibility of Making Errors: Analyzing tasks and activities to minimize errors, practice, and improve accuracy are essential.
- Postural Control: maintaining balance and orientation is fundamental for effective motor learning.
Memory and Feedback
- Memory is key in motor learning for retention and reproduction.
- Feedback in motor learning provides motivation, reinforces activity development, and informs progress. It must be administered carefully and not excessively. Providing feedback on individual progress motivates to create a mental representation of the specific activity.
Core Stability
- Core stability exercises stimulate neuromuscular recruitment, ensuring a stable spine for efficient movement.
- Interactions include neuromuscular control (neural elements), passive subsystem (osseous and ligamentous elements), and active subsystem (muscular elements).
Anatomical Core: Passive Tissues
- Bones, cartilage, and ligaments comprise the passive tissues; they have a limited role in stabilizing the spine.
Anatomical Core: Active Tissues
- Muscles provide the torque necessary for movement (concentric), control (eccentric), or prevent movement (isometric).
Anatomical Core: Stability Functions
- Anticipatory postural adjustments help prepare the body to anticipate subsequent forces and adapt for creating interactive movement by adjusting the body's position to control the exposure to force and the load applied to a joint
Anatomical Core: Stages of Exercise Management
- Section 1: Segmental control and active recruitment over global mobilisers (transversus abdominus, pelvic floor, diaphragm).
- Section 2: Maintaining segmental control and activation, introducing closed-chain exercises at low velocity and low load.
- Section 3: Maintaining segmental control, introducing open-chain exercises at high velocity and load. Movement of adjacent body segments can be used to stress core structures.
Muscle Types (Slow-Twitch and Fast-Twitch)
- Slow-twitch (ST) fibres: postural control and stabilizing muscle systems. Short, for intersegmental motion control.
- Fast-twitch (FT) fibres: global muscle systems, gross movements, and large torque. Long lever arms, suited for large forces and explosive movements. Colour: red (ST), white (FT), and pink (intermediate).
Anatomical Core: Neutral Zone
- Lumbar spine in neutral position for effective muscle support. Spinal extensor muscles inhibit in a flexed position increasing risk.
