Vagus Auricular Stimulation for Tinnitus

Vagus Auricular Stimulation for Tinnitus

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.

Adults experiencing moderate to severe tinnitus have significant impairment in their quality of life. While Cognitive Behavioral Therapy (CBT) is the most effective treatment for tinnitus, its accessibility is limited. Alternative treatment options such as masking pose significant risks and have varying success rates in achieving tinnitus cessation. Given these limitations and risks, there is a need to explore alternative treatment options for tinnitus that are both effective and easily accessible. Transcutaneous electrical stimulation of the vagus nerve has been explored as a treatment option for tinnitus using different study designs with varying response rate. In contrary, this pilot study will provide valuable insights and preliminary evidence for the effectiveness of transcutaneous stimulation of the auricular branch of the vagus nerve (TABVN-stim) utilizing a novel device that produces vibrational stimulation mimicking physiological sensory input to the ABVN. This research provides preliminary evidence for a potentially safe, non-invasive, and easily applicable treatment option for those suffering from chronic bothersome tinnitus, ultimately improving their quality of life.
