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

Standing on foam with eyes closed

Answer

Supine only until spontaneous nystagmus resolves

Answer

Walking with concurrent horizontal head movements

Question 2

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

Accepted Answer

Neuroplasticity-driven VOR gain adaptation

Answer

Strengthening of extraocular muscles through repetition

Answer

Improved labyrinthine blood flow during head movement

Answer

Reduced central sensitivity to motion stimuli

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

Looking at a target that moves opposite to head movement at the same speed

Answer

Alternately fixating between two targets during head movement

Answer

Tracking a moving target while keeping the head stationary

Question 4

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

Accepted Answer

Speed of head movement

Answer

Duration of each exercise session

Answer

Complexity of the visual background

Answer

Distance from the target

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

Reliance on smooth pursuit as the primary gaze stabilization mechanism

Answer

High-velocity head impulse training to restore VOR gain bilaterally

Answer

Optokinetic stimulation to retrain the vestibular system

Question 6

The 'x2 viewing' gaze stabilization exercise differs from x1 viewing in that:

Accepted Answer

The target moves opposite to the head at the same speed as the head

Answer

The patient performs head movements at twice the speed

Answer

The target moves opposite to the head at half the head speed

Answer

Two separate visual targets are alternated simultaneously

Question 7

Which outcome measure most directly quantifies the functional impact of gaze instability in vestibular patients?

Accepted Answer

Dynamic Visual Acuity test

Answer

Berg Balance Scale

Answer

Dynamic Gait Index

Answer

Activities-Specific Balance Confidence Scale
