A Study Of Auricular Transcutaneous Vagus Nerve Stimulation In Chronic Dizziness

Efficacy Of Auricular Transcutaneous Vagus Nerve Stimulation In Treating Chronic Dizziness

The purpose of this study is to measure the change in dizziness, as measured by change in Dizziness Handicap Inventory (DHI) score, following a 4-week treatment period with auricular transcutaneous vagus nerve stimulation (aTVNS).

Inclusion Criteria:

• Age 18-75, Persistent Postural-Perceptual Dizziness (PPPD) diagnosis per International Classification of Vestibular Disorders (ICVD).
• Persistent dizziness ≥3 months and at least 1 dizziness exacerbation/day during 2-week run-in.
• On stable medications/therapy for ≥4 weeks prior to baseline (if any).

Exclusion Criteria:

• Uncompensated peripheral/central vestibular deficit, sensory-afferent or cerebellar ataxia.
• Cardiac disease (coronary disease, unstable arrhythmia), recurrent syncope (>1 in past 12 months).
• Neck surgery, vagotomy, or any condition interfering with vagal stimulation.
• Pregnancy.
