Which test is considered the gold standard for evaluating semicircular canal function in vestibular assessment?
Answer: Caloric irrigation testing
Caloric irrigation testing selectively stimulates each horizontal semicircular canal and is considered the gold standard for identifying unilateral vestibular weakness.
The Dix-Hallpike maneuver is the primary diagnostic test for which vestibular disorder?
Answer: Benign Paroxysmal Positional Vertigo (BPPV)
The Dix-Hallpike maneuver provokes the characteristic torsional-upbeat nystagmus associated with posterior canal BPPV.
What does a canal paresis value greater than 25% indicate on caloric testing?
Answer: Unilateral vestibular weakness
A canal paresis (Jongkees formula) exceeding 25% is considered significant and indicates reduced function on the weaker side.
Which nystagmus characteristic most strongly suggests a central rather than peripheral vestibular lesion?
Answer: Direction-changing gaze-evoked nystagmus
Direction-changing gaze-evoked nystagmus (nystagmus that beats right on right gaze and left on left gaze) is a hallmark of central vestibular pathology.
The video Head Impulse Test (vHIT) assesses function of which reflex?
Answer: Vestibulo-ocular reflex (VOR)
vHIT measures the gain of the vestibulo-ocular reflex by detecting corrective saccades following rapid head impulses.
During VEMP (Vestibular Evoked Myogenic Potential) testing, cervical VEMP (cVEMP) primarily assesses which end organ?
Answer: Saccule
cVEMP is an inhibitory response recorded from the sternocleidomastoid muscle and reflects saccular and inferior vestibular nerve function.
