Vagus Auricular Stimulation for Tinnitus
In Brief
A clinical study evaluating Vibrational stimulation and Sham for Tinnitus. Completed, enrolled 40 participants across 1 site.
Detailed Summary
This pilot study is a randomized, double-blinded controlled trial of adult participants with chronic, moderate to severe bothersome subjective tinnitus. Participants will be randomly assigned to either an active auricular stimulation device group or a sham-control group.Both groups will also undergo virtual Mindfulness-Based Stress Reduction(MBSR) over 8 weeks to promote tinnitus bother reduction, and general well-being. Outcome measures will be assessed at baseline, end of intervention, and at 1-month post-intervention.
Study Details
Timeline
Interventions
The auricular stimulation device produces continuous vibrational stimulation directly to the conchae of the auricle. It is designed to stimulate the vagus nerve for neuromodulation to treat a variety of clinical indications. The system includes a pulse generator and an ear electrode device. Participants will use a vibration motor in a custom-created soft plastic clip for the left ear. Each participant will receive their own device by mail, which they will wear during the the 30 minutes mindfulness exercise portion of the 2-hour MBSR group sessions. Additionally, they will wear the devices during the 20-minute at-home MBSR activities for the remaining six days of the week, totaling 120 minutes. The total expected duration of device usage per week will be 2.5 hours or 150 minutes.
The sham device looks and is used identically to the auricular stimulation device, but does not produce vibrational stimulation. There will be no difference in the usage directions of the sham device compared to the stimulation device. Each participant will receive their own device by mail, which they will wear during the 30 minutes mindfulness exercise portion of the 2-hour MBSR group sessions. Additionally, they will wear the devices during the 20-minute at-home MBSR activities for the remaining six days of the week, totaling 120 minutes. The total expected duration of device usage per week will be 2.5 hours or 150 minutes.
