Objective: Although classical benign paroxysmal positional vertigo has generally been resolvable by routine manual repositioning maneuvers, nevertheless resistant cases and variants remain a significant problem. We investigated the efficacy of analyzing and treating positional vertigo with a system that provides unlimited, automated maneuverability of the patient while maintaining constant electronic monitoring of nystagmus.
Study design and setting: A power-driven, multi-axial positioning chair combined with ongoing infrared video-oculography was used to manage 986 subjects in a tertiary clinical setting with complaints of positional vertigo. A nystagmus-based strategy and condition-specific protocols were used.
Results: Significantly enhanced treatment outcomes were achieved, especially regarding intransigent and variant forms. Pertinent correlations were noted.
Conclusion: This multi-axial positioning chair combination provided enhanced diagnostic and treatment capabilities for managing positional vertigo, apparently due to improved analytical capability, precision repeatability, and unlimited 360-degree maneuverability.
Significance: This advancement should be considered for tertiary management of complicated labyrinthine lithiasis.
