M1 L7a: Ax Postural Control Part I Definition and Activity Framework

Question 1

What are the 3 inter-connected aspects of motor control?

Answer 1

Question 2

What is the organisation of motor control?

Answer 2

Question 3

What are 2 task factors?

Answer 3

1. Stability
2. Mobility

Question 4

When is stability required?

Answer 4

When sitting or standing with a static base

Question 5

When is mobility required?

Answer 5

When moving the base of support for (eg. walking or running)

Question 6

What are 6 characteristics of a task being manipulated to increase the demand?

Answer 6

1. Lifting a light load vs heavy load
2. Accuracy required in the task
3. Task certaincy (i.e self paced or go on signal)
4. Task complexity (i.e dual-tasking such as walking and carrying a load or walking and talking)
5. Body orientation to the task such as lifting a load in crouch position or in upright
6. Speed required

Question 7

What are 2 environmental factors?

Answer 7

1. Regulatory
2. Non-regulatory

Question 8

What are regulatory features?

Answer 8

Influence the movement so that it must conform to these features (eg. uneven surfaces- grass, sand VS firm surface)

Question 9

What are non- regulatory features?

Answer 9

Those that may affect movement performance but the movement does not have to conform to them (eg. background noise)

Question 10

What are 4 individual factors in postural control?

Answer 10

1. Perception
2. Cognition
3. Action
4. Control of action

How the action is achieved and what are the individal factors limiting that is that we as physiotherapists assess.

Question 11

What is perception of postural control?

Answer 11

Discernment of sensory information and high-level interpretation of incoming sensory information

Question 12

What is cognition of postural control?

Answer 12

Includes attention, planning, problem solving motivation, engagement and emotional aspects contributing to movement output

Question 13

What is action of postural control?

Answer 13

Includes how a certain activity is accomplished such as walking or talking

Question 14

What is control of action of postural control?

Answer 14

Requires understanding of the motor output that achieves that activity

Question 15

What are 3 characteristics of postural control?

Answer 15

1. Postural control, balance function, postural stability, static balance, dynamic balance
2. Lack of a consistent and explicit framework
3. Lack of consensus or use of valid and reliable clinical assessments in clinical trials for interventions

Question 16

What are 2 types of BOS?

Answer 16

1. Stationary BOS
2. Changing BOS

Question 17

What are 3 types of stationary BOS?

Answer 17

1. Sustain
2. Maintain
3. Retain

Question 18

What are 3 types of changing BOS?

Answer 18

1. Project
2. Propel
3. Protect

Question 19

What is postural control?

Answer 19

Control of the body’s position for orientation and balance

Question 20

What is orientation?

Answer 20

Controlling the relationship between the body segments, the task being performed ad the environment

Question 21

What is Balance?

Answer 21

Controlling the centre of mass in relation the the bass of support

Question 22

What is stationary BOS?

Answer 22

These activities require control of orientation and balance when the BOS does not change

Question 23

What is changing BOS?

Answer 23

These activities require control of orientation and balance when the BOS changes or moves

Question 24

What is SUSTAIN in stationary BOS?

Answer 24

Question 25

What is MAINTAIN in stationary BOS?

Answer 25

Question 26

What is RETRAIN in stationary BOS?

Answer 26

Question 27

What is PROJECT in changing BOS?

Answer 27

Question 28

What is PROPEL in changing BOS?

Answer 28

Question 29

What is PROTECT in changing BOS?

Answer 29

Question 30

Functional activities may require a sequence of ______ to support optimal performance

Answer 30

Postural control strategies

Use a number of postural strategies (can compensate if not sufficient for postural control )
