研究概览
简要总结
This study seeks to gather data on the effect of a device, the OtoBand, in participants who have reported symptoms of vertigo, compared to the effect of using one of two sham devices. The study is designed to be conducted remotely using video conferencing between representatives of the manufacturer of the Otoband and participants. In order to comply with requirements for non-essential contact due to the Covid-19 pandemic there will be no person to person contact in the study.
详细描述
In this phase of this pilot study, a minimum of 20 participants will be enrolled, with up to 100 participants maximum. This will provide adequately powered pilot data to measure effect size for the OtoBand and sham devices and to identify different causes of vertigo for which the OtoBand has a particularly strong effect as measured by the Otolith Vertigo Assessment Tool. After inclusion/exclusion screening and informed consent is obtained, potential participants will be assessed using the Dizziness Handicap Inventory (DHI). The DHI will be completed online.
Potential participants with a DHI score in the appropriate range will be accepted into the study. These participants will be asked to schedule an online meeting to with the study coordinator. In this online enrollment meeting, the study coordinator will review the Informed Consent and confirm other information supplied by the participant online (inclusion/exclusion) and then make an affirmative decision to enroll or not enroll participants in the study.
The participants will be randomly assigned to one of the two arms of the study (OtoBand / Sham Device A or OtoBand / Sham Device B). This is a blinded study in which every participant will be evaluated, and each participant may select the stimulation that best suits him or her on both of the study devices.
Each participant will select his/her preferred stimulation level by pressing the power level button on the study device; however, they will be blinded to which device they are using. Study participants will be asked to use the devices whenever they are having a symptom of vertigo. Each participant will be asked to record his/her level of vertigo in the online Study Diary: before putting on the device, after wearing the device for 5 minutes, after removing the device.
The study devices will record the following information regarding usage: Date and time when the device is turned on/off and the power level, Date and time when the power level is changed and the new power level.

盲法说明
Each participant will be assigned to one of the study's two arms. Participants in Arm 1 will receive, in random order, an OtoBand or Sham Device A to use for two weeks each. Participants in Arm 2 will receive, in random order, a OtoBand or Sham Device B. The participants and researchers will be blinded to which arm of the study a participant is assigned and they will not know if the device in use is effective or placebo.

结局指标
主要结局
Change in vertigo severity rating while wearing the OtoBand compared to the change in vertigo severity while wearing a sham device.
时间窗: Forms filled out daily over four week period by the study participant
The primary endpoint will be the change in vertigo severity rating while wearing the OtoBand compared to the change vertigo severity while wearing the sham device during the worst, most intense episode of vertigo within each treatment period (sham versus OtoBand device).
次要结局
- Frequency of vertigo events during each period of testing (OtoBand versus sham).(Forms filled out daily over four week period by the study participant)
- Complaints regarding usage.(Information gathered in each monitoring visits over the four week period.)
- Relationship of the bone conduction stimulation level (in dB) selected by the participant to severity of reported vertigo.(Forms filled out daily by the study participant over four week period compared to two data files captured by the devices over their two week usage.)
- Duration of use within each episode of vertigo and over the entire observation period.(Forms filled out daily over four week period by the study participant)
- Average change in vertigo severity rating while wearing the OtoBand compared to average change in vertigo severity while wearing the sham device.(Forms filled out daily over four week period by the study participant)
- Identification of the sham device with the smallest placebo effect.(Forms filled out daily over 2 week period by the study participant with the sham in each arm.)
- Durability of the effect over the observation period.(Forms filled out daily over four week period by the study participant)
- Identification of a preferred dose.(Data captured by the devices over the 14 days with each device.)
