Quantification of the Effect of the OtoBand on Objective Measures of Vertigo and Dizziness

Overview

Vestibular disorders are among the most common causes of disability in society and affect over 50% of the population over the age of 65 and a significant percentage of the younger population. Vestibular disorders have a dramatic impact on daily life impacting work, relationships, and even activities of daily living.The OtoBand has shown promise and might be beneficial for treating or improving the course of recovery from vestibular disorders. This study seeks to quantify the effect of the study device, the OtoBand, on objective measures of dizziness and vertigo in patients with vestibular dysfunction. The study will be conducted at a single-site and will be a blinded, randomized, placebo-controlled design in which participants do not know if they are receiving bone conducted stimulation 1) at a therapeutic level or 2) at a non therapeutic level.

Vestibular disorders are among the most common causes of disability in society and affect over 50% of the population over the age of 65 and a significant percentage of the younger population. Vestibular disorders have a dramatic impact on daily life impacting work, relationships, and even activities of daily living. At the current time, the mainstay of therapy for many vestibular disorders is a physical therapy called vestibular rehabilitation. While usually highly effective, this therapy is time consuming and not universally effective, in part because of inconsistent subject compliance. The use of adjuvant devices to speed recovery has been studied but very few devices have proved beneficial; the few that have shown benefit only work in special populations and are large units that cost several million dollars. In this study, the investigators will assay the efficacy of the OtoBand in participants with vertigo and dizziness. The OtoBand will be given to participants with vertigo and dizziness in patients with vestibular dysfunction. Participants will be recruited from patients who present at the Dizziness and Vertigo Institute of Los Angeles and for whom the Principal Investigators recommend a course of vestibular rehabilitation therapy. The OtoBand will be set at either a normal power (effective) or low power (lower than the power level thought to be effective, placebo device). Participants will not know if they are receiving receiving bone conducted stimulation 1) at a therapeutic level or 2) at a non therapeutic level. This study seeks to determine if, in patients going to the Dizzy and Vertigo Institute of Los Angeles for vestibular rehabilitation therapy, objective measures of dizziness and vertigo are significantly changed by wearing the OtoBand. Potential changes will be measured in the following tests: * Subjective Visual Vertical (SVV), * Sinusoidal Harmonic Acceleration (SHA), also known as rotary chair test * Spontaneous Nystagmus In this current protocol, three conditions (sham, therapeutic and no device) will be tested within an hour in a randomized sequence, with the OtoBand remaining in place throughout (turned off in the "no device" condition). The primary endpoint of the study is to determine the change(s) induced by the OtoBand in objective measures of vestibular symptoms. The secondary endpoints of the study include: * Participant's questionnaire as to which level the participant believes they used first and second (sham setting vs therapeutic setting); * Measure whether Migraine and Vestibulopathy patients experience higher benefits from a given power level as measured by objective tests (SVV, SHAs and spontaneous nystagmus); * Measure whether Migraine and Vestibulopathy patients experience any benefit from the placebo setting.
