Postural Control in Neuromuscular Disorders

Question 1

Relationship between COM and BOS

Answer 1

COM needs to stay within BOS to maintain posture and balance

Question 2

Where is the COM for a typical individual?

Answer 2

S2

Question 3

What impacts where the COM falls for an individual?

Answer 3

Any posture differences change the location of the COM of the individual

Question 4

Answer 4

1. Biomechanical constraints
2. Movement strategies
3. Cognitive processing
4. Control of dynamics
5. Orientation in space
6. Sensory strategies

Question 5

What body systems contribute to postural control/stability?

Answer 5

1. Vision
2. Vestibular
3. Proprioception
4. Exteroception

Question 6

Answer 6

Spatial orientation (location and attention)

Question 7

Answer 7

Object identification and recognition and object quality (the “what” pathway)
