vestibular Flashcards
compare canalthiasis v cupulolithiasis
canalthiasis
- short duration, less than 1 min
cupulolithiasis
- persistant in duration, more than 1 min
cupuLOlithiasis - LOnger
upbeating torsional nystagmus
posterior canal
PUP: posterior upward
downbeating torsional nystagmus
anterior canal
intervention for treating canalilithiasis
eply or canal repositioning manuever, CRM
intervention for treating cupulolithiasis
semont or liberatory
this is the only intervention where you position the head on the non-affected side
what intervention do you do when your pt cannot tolerate CRM
brandt daroff exercise
what position explain is the neck when performing supine roll test
neck flexed to 20deg
geotropic v apogeotropic
geotropic
- towards ground
- canalithiasis
(towards ground; ground has canals)
~ the side that is more intense is the affected side
apogeotropic
- away from ground
- cupulolithiasis
~ the side that is less intense is the affected side
intervention for horizontal BPPV
BBQ roll
if someone is presenting with abnormal smooth pursuits and saccades, what do you do
central vestibular pathology - refer out
with someone with BPPV, is their VOR intact or not?
yes, its intact
compare central v peripheral vestibular pathology
central:
- ataxia
- abnormal smooth pursuits and saccades
- diplopia and other red flags (difficulty swallowing)
- usually no hearing loss (intact)
- pendular nystagmus
- persistant vertical nystagmus
- visual fixation does not improve
peripheral
- no ataxia, if so, very mild
- normal smoot pusuits and saccades
- hearing loss, fullness in ears, tinnitus
- nystagmus
- symptoms improve
labyrinthitis
inflammation of the labyrinth
sudden onset of vertigo, n/v
(+) head impulse test
duration: days to weeks
hearing loss, tinnitus
vestibular neuritis
inflammation of the nerve
sudden onset of vertigo, n/v
(+) head impulse test
duration: days to weeks
meniere’s disease
overproduction of fluid within the inner ear - increases pressure = vertigo
symptoms:
vertigo
hearing loss
tinnitus
aural fullness
duration: mintues to hours
