Categories of Motor Skills

Question 1

Transitional mobility

Answer 1

Ability to move from one posture to another

BOS and or COM are changing

Question 2

Example of transitional mobility

Answer 2

Rolling; supine to sit, sit to stand; transfers

Question 3

Impairments to use transitional mobility

Answer 3

Failure to initiate or sustain movements through the range; poorly controlled movements

Question 4

Static postural control

Answer 4

Ability to maintain postural stability and orientation with the COM over the BOS with the body not in motion; BOS is fixed

Question 5

Examples of static postural control

Answer 5

Holding in antigravity postures; prone on elbows; quadruped, sitting, half kneeling, tall kneeling, modified plantigrade, or standing

Question 6

Impairment to use static postural control

Answer 6

Failure to maintain a stead posture; excessive postural sway; wide BOS; high guard arm position or handhold; loss of balance (COM exceeds BOS)

Question 7

Dynamic postural control

Answer 7

Ability to maintain postural stability and orientation with COM over BOS while parts of the body are in motion; BOS is fixed

Question 8

Examples of dynamic postural control

Answer 8

Weight shifting; UE reaching in any or the above antigravity postures; LE stepping in modified plantigrade or standing

Question 9

Impairments to use dynamic postural control for

Answer 9

failure to maintain or control posture during dynamic trunk or extremity movements; loss of balance

Question 10

Skill

Answer 10

Ability to consistently perform coordinated UE and LE movement sequences for the purpose of investigation and interaction with physical and social environment; during locomotion, COM is in motion and BOS is changing

Question 11

Examples of skills

Answer 11

UE skills grasp and manipulation; LE skill: bipedal locomotion

Question 12

Impairments to use skill

Answer 12

poorly coordinated movements; lack of precision control, consistency and economy of effort
