Motor Control

1
Motor Control Learning

• Level of control in all learning
• Learning produces changes in control

2

Motor Skill Defined

• Requires body /or limb movement
• Voluntary
• Goal directed
• Learned

4
Characteristics of Human Action

• Flexibility
• Ability to recruit different muscles and joints
  to achieve same action
• Uniqueness
• No two movements are ever performed in exactly
  the same way

5
Characteristics of Human Action

• Consistency of Action
• Temporal and spatial aspects of a movement remain
  relatively stable from one performance to the
  next
• Modifiability of Action
• Ability to alter a movement pattern, even as it
  is being executed

6
Classification of Motor Skills
7
One-Dimensional Classifications

• SIZE OF MUSCULATURE INVOLVED
• Gross motor Fine motor

8
One-Dimensional Classifications

• DISTINCTIVENESS OF MOVEMENT
• Discrete Continuous

9
One-Dimensional Classifications

• STABILITY OF ENVIRONMENT
• Closed Open

10
Environmental Dimension

• Demands placed on performer by the environment
  (Performance Space)
• Move Where? Spatial
• Move When? Temporal
• Move Where When? Spatial Temporal

Constraints
11
Closed Skill

• Characteristics
• Self-paced
• Fixed Environment
• Spatial Control
• Highly Predictable

12
Open Skill

• Characteristics
• Externally-paced
• Changing Environment
• Spatial Temporal control
• Skill Level of Performer

13
Two-Dimensional Classification

• Stationary Motion
• No variability Variability
