CVT Gaze Stabilization & Oculomotor Assessment 3

Question 1

For a patient with acute unilateral vestibular hypofunction, in which position should gaze stabilization exercises be initiated?

Accepted Answer

Sitting, progressing to standing as tolerated

Answer

GSE should begin in sitting to minimize fall risk in the acute stage, with progressive advancement to standing and then dynamic activities as balance improves.

Question 2

The primary mechanism by which gaze stabilization exercises improve VOR function is:

Accepted Answer

Neuroplasticity-driven VOR gain adaptation

Answer

GSE promote neuroplasticity-driven VOR adaptation where repeated mismatch between head movement and retinal slip drives the brain to recalibrate VOR gain.

Question 3

Which statement best describes the 'x1 viewing' gaze stabilization exercise?

Accepted Answer

Holding a stationary visual target in focus while actively moving the head

Answer

In x1 viewing, the patient holds a stationary target and moves their head while maintaining focus, creating a retinal slip signal that drives VOR adaptation.

Question 4

Which parameter is typically progressed FIRST when advancing gaze stabilization exercises?

Accepted Answer

Speed of head movement

Answer

Speed of head movement is typically the first parameter progressed in GSE because faster movements create greater VOR challenge and drive more effective VOR adaptation.

Question 5

For patients with bilateral vestibular hypofunction, which gaze stabilization strategy is most appropriate?

Accepted Answer

Emphasis on cervico-ocular reflex augmentation and maximizing visual reliance

Answer

Patients with bilateral vestibular hypofunction cannot rely on VOR recovery, so therapy emphasizes alternative strategies such as cervico-ocular reflex augmentation, preprogrammed eye movements, and maximizing visual reliance.
