CVT Vestibular Rehabilitation Techniques 2

Question 1

Which technique involves moving the patient from sitting to side-lying and is used to treat posterior semicircular canal BPPV?

Accepted Answer

Semont maneuver

Answer

The Semont (liberatory) maneuver moves the patient rapidly from sitting to side-lying to dislodge debris from the posterior semicircular canal.

Question 2

During gaze stabilization exercises, a patient tracks a target while moving the head. What is the primary goal of this VOR x1 exercise?

Accepted Answer

Enhance VOR gain to maintain stable gaze during head movement

Answer

VOR x1 exercises aim to increase VOR gain so the eyes move equally and opposite to head movement, stabilizing the visual image.

Question 3

A patient with bilateral vestibular hypofunction is BEST served by which rehabilitation approach?

Accepted Answer

Substitution and habituation strategies using visual and somatosensory cues

Answer

Bilateral vestibular hypofunction cannot be restored via repositioning; therapy focuses on substitution with alternative sensory systems and habituation.

Question 4

Which outcome measure assesses dynamic balance by requiring patients to walk while turning their head horizontally?

Accepted Answer

Dynamic Gait Index (DGI)

Answer

The Dynamic Gait Index includes a task of walking with horizontal head turns, directly challenging vestibulo-spinal reflexes during locomotion.

Question 5

What is the primary mechanism behind habituation exercises for vestibular disorders?

Accepted Answer

Repeated exposure to provocative movements to reduce CNS sensitivity to the stimulus

Answer

Habituation relies on neuroplasticity: repeated exposure to a provocative stimulus gradually reduces the symptomatic response over time.
