Motor Learning First define: What is a motor skill? o A motor skill is a task that has a specific goal to achieve. Then classify: So we can establish generalizations. So we can develop theories about learning and performance. Guidelines for strategies to enhance motor skill learning and rehabilitation. Definitions Skill o Task that has a specific goal to achieve. Motor Skill o Skill that requires voluntary body and/or limb movement to achieve the goal. o Need to be learned and practical. Movements o Behavior characteristics of a specific limb or combination of limbs. Actions o Skills Classification Systems Size of Musculature Gross Motor Skills Large musculature: (Fundamental Motor Skills) Fine Motor Skills Small muscles: (Hand-To-Eye Coordination, Very Precise) Distinctiveness of Movements Discrete Motor Skill One distinct movement: (Flipping A Switch, Beginning-End) Serial Motor Skill Several discrete movements in a series or sequence. Continuous Motor Skill Repetitive movements Stability of Environment Closed Motor Skill o Stable environment o Nothing moving, or changing Open Motor Skill o Object or content changes during performance o To be successful, must adapt and adjust Applications Measurement of Motor Performance

o Need assessments to make judgments on physical abilities, deficiencies, & improvements. Performance Outcome Measures o How far, how fast, how many, how much. o Nothing specific about behavior or skill. Performance Production Measures o How functioning, acting, operating. o Ex.) Velocity Acceleration Angles Torque Reaction Time How long it takes to initiate movement Simple: o One Signal, One Response Choice: o More Than One Signal, Each With Its Own Response Discrimination: o More Than One Signal and Only One Response Error Measures One Dimension o Absolute error: Absolute differences (Outcome) o Constant error: Directional Bias o Variable error: Performance consistency Two Dimensions o Continuous Skills o Root-mean-squared-error (RMSE) Average Error Kinematic Measures Displacement: Spatial position. Velocity: Rate of change in position. o Ex.) Speed Acceleration: Change in velocity during movement. Force involved in motion o Electromyography (EMG) to figure out muscle force.
