Vestibular classifications

Question 1

what are the 10 classifications

Answer 1

1. vestibular/somatosensory integration at rest
2. canal function
3. gaze stability
4. otolith function
5. impaired postural control
6. oculomotor function
7. cervicogenic- dizziness
8. visual motion hypersensitivity
9. somatosensory hypersensitvity
10. head position provoked dizziness

Question 2

what is the testing of vestibular/somatosensory integration at rest

Answer 2

sensation of motion at rest:
-positive= sensation of motion inside ones head with eyes closed and body stable

interpretation: asymmetry of information from inner ear

Question 3

what is the intervention for vestibular/somatosensory integration at rest

Answer 3

settling: matching vestibular/somatosensory inputs

-find position of incresed stability like hooklying
-weights on body
-axial loading

Question 4

what is canal function testing

Answer 4

head motion provoked dizziness
positive: dizziness

means: asymmetry of info from inner ear canals or brain

Question 5

what is canal function intervention

Answer 5

1. rolling: eyes closed supine to prone
2. head turns/pithc eyes closed seated
3. standing spinning eyes closed
4. chair spins eyes closed

Question 6

what is some gaze stability testing

Answer 6

VOR

1. head impulse test: positive= eyes slip off target
2. dynamic visual ctivity: gold standard.positive= loss of >3 lines of visual acuity (blurred)
3. gaze stability with head turns. postiive= blurred vision during head motion

Question 7

what is gaze stablityi intervention

Answer 7

focus on target, move head in plane of canals, progressing speed

target must be in focus

Question 8

what is otolith function testing

Answer 8

head righting

-tilt board/rocker board
-lateral reaching
-tandem stance/tandem gait
-2x4

Question 9

what is some oculomotor function testing

Answer 9

1. saccades
2. smooth pursuits
3. convergence/divergence

means: possible visual impairment
screen for central dysfunction

Question 10

what is ocoulmotor function intervention

Answer 10

1. saccades all planes
2. smooth persuits alll planes
3. brock string

Question 11

what is cervicogenic dizziness testing

Answer 11

1. body rotation under stable head
2. laser

Question 12

what is cervicogenic dizziness intervention

Answer 12

1. body rot under stable head
2. laser and target training
3. C/s joint mobility and miuscle retraining
4. isolated c/s motion frmo oculotmotor

Question 13

what is visual motion hypersensitivity testing

Answer 13

1. VMHQ
2. oculomtoor screen
3. optokinetic stimulus test

Question 14

what is visual motion hypersensitivity intervention

Answer 14

1. compensation: decrease visual stimulus
2. adaptation techinques

Question 15

what is somatosensory hypersensitivity testing

Answer 15

1. joint loading or increased surface area contact
2. report of rocking sensation under feet

Question 16

what is somatosensory hypersensitivity intervention

Answer 16

1. progressive and/or graded exposure to joint loading wiht increased surface area tactile input
2. increased input through ankles
3. beach walking or stomping
4. normalize movmenet patterns
