Neural control of posture
6 important questions on Neural control of posture
What are the three types for forces?
- Gravity
- Ground reaction force
- External forces
All the forces and moment should be in equilibrium to be in balance.
What are the three mechanisms for postural control?
- Move the COP
- Move the COM
- Change the Base of support
Describe the 'move the COP mechanisms'
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
Describe the ankle strategy in the sagittal plane
Falling to the back: activation of ventral muscle (tibialis anterior, quadriceps, abdominal muscles)
Someone could only perform the ankle strategy if:
- the leg muscle are strong enough
- the ankle mobility is good
- and there is a large base of support
Describe the 'move the COM mechanisms'
What sensory systems are used for balance control?
- Vision
- Vestibulum
- Somatosensation
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
