Task Analysis

Question 1

Stages of Motor Control

Answer 1

1. Mobility
2. Stability
3. Controlled Mobility
4. Skill

Question 2

Mobility

Answer 2

• Ability to initiate functional movement in a dependent position
• Anti-gravity control is not fully developed
• Movements are not sustained or well-coordinated

Question 3

Stability

Answer 3

• Ability to maintain a steady position in an anti-gravity, weight bearing position
• Static postural control
• Includes muscle stability/tonic holding & postural stability/co-contraction

Question 4

Controlled Mobility

Answer 4

• Ability to alter a position or move into a new weight-bearing position while maintaining postural control
• Weight-shifting ability
• Referred as dynamic postural control
• Distal segments fixed, proximal segments mobile

Question 5

Skill

Answer 5

• Proximal segments stabilize while distal segments are free for function
• Ex. Counter-rotation during gait

Question 6

Hedman Model for Motor Control

Answer 6

• Six stages: Initial condition, preparation, initiation, execution, termination, outcome
