Benign paroxysmal positional vertigo (BPPV) is the most common peripheral vestibular disorder and is typically diagnosed based on characteristic positional nystagmus. Although video head impulse testing (vHIT) is increasingly used in vestibular disorders, its role in BPPV remains unclear, particularly in less common variants....

vHIT is not a validated replacement for positional nystagmus testing (e.g., Dix-Hallpike) in diagnosing BPPV; clinicians should continue using established positional tests as the primary diagnostic tool until stronger evidence supports vHIT for this indication.
BPPV is the most common vestibular disorder, and clarifying whether vHIT adds diagnostic value could influence vestibular assessment protocols across audiology and ENT practices.
- 01Systematic review examines vHIT diagnostic accuracy for BPPV.
- 02Standard positional nystagmus testing (e.g., Dix-Hallpike) is the established reference standard for BPPV.
- 03vHIT primarily assesses semicircular canal VOR gain, which is typically normal in BPPV.
- 04Findings may help define the appropriate (limited) role of vHIT in BPPV workup.
- 05Published in Audiology Research as a systematic review.
vHIT has diagnostic utility for benign paroxysmal positional vertigo.
