Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Vagus Nerve Stimulation (VNS) is a validated and FDA-approved therapy that has improved the lives of many individuals with epilepsy and depression and has shown promise for treating chronic pain. However, there is moderate morbidity associated with the surgical procedure and maintenance of VNS. The study team has developed a novel, non-invasive procedure based on the neurobiology of VNS treatment which is termed Respiratory-gated Auricular Vagal Afferent Nerve Stimulation (RAVANS). The investigators hope to maximize efficacy and better understand applicability of RAVANS by applying this to chronic pain patients with a range of psychiatric and psychological comorbidity. This high-distress subpopulation of chronic pain patients has been notoriously difficult to treat and is in need of new, innovative therapies. The investigators propose applying electrical stimulation of the somatosensory vagal afferent receptors in the ear using transcutaneous-VNS (t-VNS) during the exhalation phase of breathing in order to augment the clinical efficacy of t-VNS. This proposal includes a single blinded, controlled design for testing the impact of RAVANS therapy on pain and mood fro chronic pain. Patients will complete 2 in-person visits, one with RAVANS therapy and one with non-RAVANS stimulation. During each session, participants will complete questionnaires, quantitative sensory testing (QST), and receive either real or sham RAVANS stimulation.
