CVT Vestibular Rehabilitation Techniques 3

Question 1

A therapist prescribes VOR x2 exercises. How does this differ mechanically from VOR x1?

Accepted Answer

The target moves in the same direction as the head at double speed

Answer

In VOR x2, the target moves in the same direction as the head, requiring the VOR to generate twice the normal gain to maintain stable gaze.

Question 2

Which parameter should be GRADUALLY increased when progressing gaze stabilization exercises to avoid over-provoking symptoms?

Accepted Answer

Head movement velocity and frequency

Answer

Progressive increases in head velocity and frequency challenge the VOR incrementally without causing symptom exacerbation that could limit participation.

Question 3

The Fukuda stepping test assesses which vestibular function?

Accepted Answer

Asymmetry of vestibulo-spinal reflexes by measuring body rotation during stepping in place with eyes closed

Answer

The Fukuda stepping test detects vestibulo-spinal asymmetry; patients with unilateral hypofunction rotate toward the lesion side when stepping in place blindfolded.

Question 4

What is the primary reason a CVT should avoid prescribing canalith repositioning maneuvers for a patient with a perilymph fistula?

Accepted Answer

Positional changes may worsen the fistula and increase symptoms

Answer

Perilymph fistulas involve a tear in the oval or round window membranes, and aggressive positional maneuvers can exacerbate the leak and symptoms.

Question 5

Which functional balance task BEST challenges the vestibulospinal reflex in a community-ambulatory vestibular patient?

Accepted Answer

Tandem gait with head turns on an uneven surface

Answer

Tandem gait with simultaneous head turns on an uneven surface integrates vestibulospinal demands with reduced base of support and somatosensory perturbation.
