Summary

Benign Paroxysmal Positional Vertigo (BPPV) is one of the most common causes of vertigo and the most common vestibular disorder of the inner ear. BPPV is the result of small free-floating particles (canaliths) in the posterior semicircular canals where they aggravate the sensory apparatus and induce sudden and severe attacks of vertigo when the head is turned into certain positions. The treatment of BPPV was revolutionized by the introduction of the Epley maneuver, a sequence of head movements that use gravity to reposition the canaliths within the inner ear. The Epley maneuver provides prompt relief from vertigo in approximately 80% of patients. The innovation, the Vertigone goggle, provides both physician and patient with visual feedback to guide them through an accurate Epley maneuver. This changes the current treatment paradigm for BPPV, greatly increasing the availability of the maneuver to non-specialist physicians, nurse practitioners, physician's assistants and physical therapists. The device is designed so that the patient with recurrent vertigo can use the goggle to treat BPPV at home. The goggle is currently a pre-market prototype. The hypothesis for the study is that accuracy in the performance of the Epley maneuver correlates with improved clinical resolution of vertigo in BPPV patients. If the hypothesis is true, then there is a clear case for the utility of the visual feedback provided by the VertiGONE goggle in performing the maneuver.

Interventions

Type	Name	Description
DEVICE	Goggle with 20 degree error	The Vertigone Goggle is modified such that the head positions and visual feedback indicators are offset 20° from the classic Epley positions.
DEVICE	Optimized Goggle	The classic Epley maneuver involves 3 head positions: 1) the patient supine, the neck is extended 20°and the head turned 45° towards the affected ear, 2) the patient rotates his head 90° to the contralateral side, with the final head position 45° from vertical, 3) the patient turns his head 135° towards the floor on the contralateral side. For the classic Epley maneuver, the goggle coach ball markings will be set for correct positioning.
