NCS Vestibular Rehabilitation 2

Question 1

Gaze stabilization exercises in vestibular rehabilitation primarily aim to improve which reflex?

Accepted Answer

Vestibulo-ocular reflex (VOR)

Answer

Gaze stabilization exercises (VOR x1 and x2 viewing tasks) are designed to enhance VOR gain and improve retinal image stability during head movement.

Question 2

The Sensory Organization Test (SOT), a component of computerized dynamic posturography, evaluates the relative contributions of which three sensory systems to balance?

Accepted Answer

Visual, vestibular, and somatosensory

Answer

The SOT systematically alters visual and surface conditions across six conditions to isolate the relative contributions of visual, vestibular, and somatosensory inputs to postural control.

Question 3

The supine roll test (Pagnini-McClure test) is the primary diagnostic maneuver for BPPV affecting which canal?

Accepted Answer

Horizontal semicircular canal

Answer

The supine roll test positions the horizontal canal in the plane of gravity; rolling the supine patient's head 90° to each side elicits geotropic or apogeotropic horizontal nystagmus if canaliths are present.

Question 4

In the Barbecue roll (Lempert) maneuver used to treat horizontal canal BPPV, the patient is rotated:

Accepted Answer

360° in four sequential 90° steps toward the unaffected side

Answer

The Barbecue roll maneuver guides canaliths from the horizontal canal back to the utricle by rotating the patient 360° in four 90° incremental steps toward the unaffected side.

Question 5

Habituation exercises for vestibular dysfunction are MOST appropriate for patients with:

Accepted Answer

Chronic motion sensitivity from stable unilateral vestibular hypofunction

Answer

Habituation exercises, which use repeated exposure to symptom-provoking movements to reduce sensitivity, are most effective in patients with stable peripheral vestibular lesions causing motion-triggered symptoms.
