Balance and Fall Risk Flashcards
1
Q
Main quantities of balance
A
- Center of pressure
- Limits of stability
- Functional limits of stability
2
Q
Center of pressure pushes _________________ back to stability
A
- Center of mass
3
Q
Typical angular sway in the anterior posterior direction
A
- 12.5º
4
Q
Postural control requires what 3 things
A
- Sensory function
- Sensory integration function
- Movement strategies
5
Q
Good postural control equals better _________
A
- Confinement
6
Q
Higher COP/COM displacement indicates relatively _______ control
A
- Poor
7
Q
Static versus dynamic balance
A
- Static: no intention to move, still moving though, & perturbations are internal
- Dynamic: could be “do this specific task” and could be “maintain balance despite…”
8
Q
Order of balance/reactive strategies as perturbation strength increase
A
- Ankle strategy
- Hip strategy
- Stepping strategy
9
Q
Excursion based tests
A
- Limits of stability
- STAR, Y-balance
- Functional reach
10
Q
Control based tests
A
- Computerized dynamic posturography
- Rhythmic Weight Shift
- Time on target
- Time to stabilization
- “Game” tasks

A
- Vibration
- Stochastic resonance stimulation
- Galvanic vestibular stimulation
