This is a non-randomized pilot study to test the efficacy of neuromodulation via caloric stimulation on vestibular migraines. All subject who meet the study criteria will be in an active treatment group. All subjects will report the frequency of the migraines and undergo periodic testing of symptoms.

Arms Assigned Interventions
Experimental: Device
Device: Device

The following parameters will be set for active treatments using the CVS Device:

  • A standardized CVS time-varying waveform lasting approximately 19 minutes will be used. Treatments will be administered up to twice daily. The two daily treatments should ideally be separated by at least one hour.
  • The waveform schedule will consist of a warm sawtooth delivered to one ear and a cold sawtooth delivered to the other ear. The warm sawtooth will go from body temperature to 42 °C, and the cold sawtooth will go from body temperature to 17 °C. The two waveforms will be delivered simultaneously, but will have different oscillation frequencies.
Other Name: Caloric stimulation

Detailed Description:

This is a non-blinded, non-randomized pilot study of individuals with vestibular migraines. The goal is to test the efficacy of neuromodulation on both migraine and dizziness symptoms in patients with documented vestibular migraines. Treatment will consist of 9 months of active treatment followed by 3 months of observation. The active treatment requires two daily 20 minute sessions wearing a device over the ears that delivers a very small amount of warm air to the ears. All subjects will undergo a series of tests at baseline and at discrete intervals during the 1 year of observation.

Primary and Secondary endpoints are listed below:• Primary Efficacy Endpoints

  1. Reduction in the frequency and severity of migraine headaches (self reported in pain diary)
  2. Reduction in the frequency and intensity of perceived vestibular symptoms (Dizziness Handicap Inventory (DHI), Activity Balance confidence scale (ABC), Oscillopsia Test, Symptoms questionnaire), OVRT Goggle profile.

Secondary Efficacy Endpoints for the Pilot Study

  1. Improvement in sleep quality and/or quantity as assessed by the Epworth Sleep Scale.
  2. Improvement in quality of life as assessed by the HIT-6 survey.
  3. Improvement in mood/anxiety as assessed with the T2 Mood Tracker app (National Center for Telehealth & Technology).

Ages Eligible for Study:   18 Years to 75 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:
