What this trial studies

This clinical trial investigates the effects of transcutaneous vagus nerve stimulation (tVNS) on patients suffering from long COVID and chronic fatigue syndrome. The study aims to compare two different sets of stimulation parameters to identify which one most effectively improves the health-related quality of life over a 6-week period. Participants will use the assigned device for at least 30 out of 42 opportunities, and those who respond positively will continue with the best device for an additional 6 weeks. The trial is motivated by the need for effective treatments for post-acute sequelae of SARS-CoV-2 infection, as current options are limited.

Who should consider this trial

Good fit: Ideal candidates are individuals who have had a documented COVID-19 infection and meet the criteria for chronic fatigue syndrome.

Not a fit: Patients who are severely obese (BMI ≥30), hospitalized for COVID-19, or pregnant may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve the quality of life for patients suffering from long COVID and chronic fatigue syndrome.

How similar studies have performed: Previous open-label studies have shown promising results for tVNS in similar patient populations, indicating potential for success in this trial.
