A patient with Mal de Débarquement syndrome reports persistent rocking sensations after a cruise. Which intervention has shown the MOST evidence for this condition?
Answer: Readaptation protocol using rolling optokinetic drum with concurrent head movement
The readaptation protocol using optokinetic stimulation paired with head movement has the strongest current evidence for remitting Mal de Débarquement syndrome.
Which test uses video goggles to detect canal-specific VOR deficits by applying high-acceleration head impulses in the plane of each semicircular canal?
Answer: Video Head Impulse Test (vHIT)
The vHIT measures VOR gain for each individual semicircular canal using high-frequency, high-acceleration head impulses recorded by video-based eye tracking.
During balance retraining, what is the purpose of the 'somatosensory conflict' condition in which the support surface tilts in proportion to body sway?
Answer: To render ankle/foot proprioceptive cues inaccurate, isolating vestibular and visual contributions to balance
A sway-referenced platform moves with the patient, making proprioceptive signals unreliable, so balance must be maintained using vestibular and visual information only.
A patient presents with cupulolithiasis of the horizontal canal. Which feature distinguishes this from canalithiasis of the same canal?
Answer: Nystagmus is apogeotropic and does not fatigue with repeated positioning
In horizontal canal cupulolithiasis, debris adheres to the cupula producing persistent apogeotropic nystagmus that does not fatigue, unlike the transient geotropic nystagmus of canalithiasis.
Which strategy is employed when a vestibular patient is taught to use increased hip and trunk movement to maintain balance rather than relying on ankle strategy?
Answer: Motor strategy retraining — promoting hip strategy
Motor strategy retraining explicitly teaches patients to activate the hip strategy for broader perturbations when ankle strategy is insufficient or unavailable.
What is the MAIN rationale for prescribing tai chi as a supplemental intervention in a vestibular rehabilitation program?
Answer: Slow, controlled weight shifts and multidirectional postural challenges improve balance confidence and vestibulospinal function
Tai chi's slow, deliberate weight transfers and multi-planar stance changes challenge postural control in ways that complement vestibular rehabilitation exercise.
A CVT documents 'catch-up saccades' during a head impulse test. What does this finding indicate?
Answer: Impaired VOR on the tested side, with corrective saccades compensating for insufficient eye stabilization
Catch-up saccades occur when VOR gain is insufficient; the eyes lag behind the head and a corrective saccade is required to re-fixate the target, indicating peripheral hypofunction on that side.
