Transcutaneous Vagus Nerve Stimulation as a Complementary Therapy to Exercise in Chronic Fatigue

Sponsor: Centre Hospitalier Universitaire de Saint Etienne

Summary

Chronic fatigue is enhanced by adapted physical activity (APA) programs. Patients consulting on St Etienne hospital and suffering from fibromyalgia and long Covid benefit from a 4-6 week APA program, with 2 sessions per week. While most patients are improved by these exercise-training programs, for some the benefits remain very modest, and patients describe persistent fatigue. The literature unanimously describes the necessity of longer APA protocols (8-12 weeks, 2-3 sessions/week) for fatigue reduction in fibromyalgia and long Covid. However, it seems difficult to adhere to an optimal program as described in the literature for these fatigued patients. The investigators want to test a device that would both reduce fatigue and improve recovery between APA sessions, in order to gradually reach the recommendations for APA practice. Transcutaneous vagal nerve stimulation (tVNS) seems to be a promising approach. Thus, combining an APA intervention with a tVNS protocol could potentiate the expected and now well-known effect of exercise.
