More research examining the potential role of vagus nerve stimulation continues to be published. This paper reviews the potential clinical benefits of using transcutaneous vagus nerve stimulation as adjunctive therapy for COVID-19.
The authors conclude, “Vagal neurostimulation has a wide field of therapeutic benefit for patients and should be combined with the best current medical strategies. The development of non-invasive vagal nerve stimulation (t-VNS), a non-pharmacological adjuvant, may help reduce the burden of COVID-19 and deserve to be investigated.” [emphasis added]
