Q

definitions of balance

A

ability to receive afferent sensory input and organize it in an appropriate manner to maintain

upright posture and COG over to BOS

** must have appropriate strength as well**

Q

automatic postural responses

A

to keep COG over BOS

occurs rapidly, not under volitational control

16
Q

hip strategy

A

head and hips move in opposite direction

muscle contraction are from proximal to distal

17
Q

when is hip strategy used

A

when sway is large, fast and nearing the limit of stability

18
Q

example of hip strategy

A

anterior to posterior push will cause hip/trunk flexion

19
Q

stepping strategy

A

LE attempts to re-establish a new BOS w/ the active limb by taking a step

20
Q

when is stepping strategy done

A

done when the COG exceeds BOS

21
Q

vestibular system role in balance

A

stabilize visual images on the fovea of the retina during head movement to allow clear vision

maintain postural stability, esp during movement of the head

provide info used for spatial orientation

22
Q

standing tests

A

standing progression tests

23
Q

standing progression tests are done with

A

arms crossed

must be held for 20-30 s

24
Q

positive standing progression test

A

pt is unable to maintain position or excessive sway is noted

25
examples of standing progression tests
feet together (romberg test) tandem (sharpened/tandem romberg) single leg stance
26
clinical test for sensory interaction on balance (CTSIB) is used to
differentiate which afferent system is not contributing to balance often called foam and dome testing
27
CTSIB attempts to
take away either 1 or 2 of the 3 sensory components of balance see how the remaining structures compensate
28
how many components of CTSIB
6
29
how do we progress CTSIB
standing feet together --> stance --> tandem --> SLS
30
goal of CTSIB
not lose their balance for 30 s for each portion of the test
31
interpreting the results
if a pt fails a test remaining systems are unable to compensate
32
CTSIB results --> eyes are closed
vestibular and SS are working
33
CTSIB results --> isolating
isolate the vestib and the SS on its own or see how the vestib works with vision or how SS w/ vision
34
CTSIB results --> what if vestib fails on its own with conjunction w/ vision
vestib is at fault
35
how do we eliminate vision
close their eyes
36
how do we eliminate SS
stand on unstable surface
37
how do we eliminate vestibular
suppose to put a lantern (foam) over their head or move the walls (via a machine) clinically have the pt turn thier head side to side
38
fxnal scales
fxnal reach test berg tinetti DGI (dynamic gait index)
