Due to lack of interest, the COVID-19 Long Hauler Vagus Nerve Stimulation Trial has been cancelled.

There are no plans at this time to re-open the trial in the future.

Brief Study Description

As our understanding of coronavirus 2 (SARS-CoV-2) and the mechanisms involved in developing acute coronavirus disease 2019 (COVID-19) expand, there is a growing number of clinical cases of COVID-19 with chronic symptoms who are presently referred to as COVID long-haulers.

COVID-19 illness involves other body organs besides the lungs. In recovered patients, chronic symptoms may include dysautonomia, fatigue, “brain fog,” abdominal pain, bloating, gastroparesis, and nausea, headache, arthralgia, myalgia and sleep disturbance.  Chronic depression and anxiety are also common.

Dysautonomia itself can contribute to cardiac symptoms that include chest pain, palpitations, exercise intolerance, and orthostatic intolerance.

Our premise is that the chronic inflammation associate with COVID-19 illness is a contributing factor to the dysautonomia experienced by long-haulers. Transcutaneous vagus nerve stimulation is capable of reduce of pro-inflammatory cytokines and improve clinical outcome in a variety of medical conditions including inflammatory bowel disease, rheumatoid arthritis and sepsis.

Our study will evaluate autonomic nervous system function through a symptom survey and advanced spectral analysis. Spectral analysis is pain less and involves interpretation of autonomic signals obtained from a simple electrocardiogram.

If evidence of autonomic dysfunction is found, the study subjects will be offered treatment with daily, at home, transcutaneous vagus nerve stimulation (tVNS). tVNS is operated through an iPhone or Android smartphone, is painless, safe and require only 3 5-minute treatments per day. Repeat symptom survey and spectral analysis testing will be performed in 4 weeks.

Study Overview

Study involves assessing patients for autonomic dysfunction with both a survey and spectral analysis. Those demonstrating evidence of autonomic dysfunction will be offered treatment with transcutaneous vagus nerve stimulation using the Vitality Smart Cable.

Patients will self-administer 3, 5-minute treatments per day for 4 weeks.  After which time they will return to the office for re-evaluation with the same survey and spectral analysis.

Number of Subjects for Pilot Trial

  • 10 subjects will be evaluated and will be assessed in 2 groups of 5.  Enrollment might be expanded if there is evidence of efficacy.
  • Inclusion and exclusion criteria are listed below.

Cost to Patient

The study and use of vagus nerve stimulator will be performed at no cost to the patient. Other costs such as transportation or housing if traveling from outside of the Arizona area will not be reimbursed.
