Transcutaneous Vagus Nerve Stimulation (tVNS) for Improved Recovery After Exertion.
Sponsor: University Hospital Tuebingen
Summary
Widespread infection with SARS-CoV-2 has resulted in millions of people having Post-COVID. Post-COVID is a complex, non-monolithic disease with diverse clinical manifestations. Symptoms range from fatigue, brain fog, muscle aches and shortness of breath, affecting multiple organ systems simultaneously. To directly address this multi-organ component of Post-COVID, innovative treatment methods are urgently needed. One potential treatment that we will investigate in our study, is the intervention via the vagus nerve, as the cranial nerve plays a central role in communication between the body and the brain and influences targeted behavior. This innovative approach is based on our clinically relevant findings regarding the effects where acute tVNS increased the level of effort (Neuser et al., 2020; Ferstl et al., 2021), specifically targeting a key symptom of Post-COVID. In the proposed study, the investigators aim to investigate the effectiveness of transcutaneous vagus nerve stimulation (tVNS) as a non-invasive, self-administered treatment for Post-COVID symptoms at home. To evaluate the clinically relevant effects of repeated taVNS application (high-intensity stimulation), the investigators will employ a randomized cross-over design to investigate stimulation-induced changes in fatigue, depression and motivation to work for reward compared to low-intensity stimulation and to a control group.

Conditions
Interventions
transcutaneous vagus nerve stimulation
The study employs a CE-certified tVNS® E device, ensuring European safety standards (EU regulation 2017/745 on medical devices). This device features a stimulation cycle of 28 seconds on and 32 seconds off, with a 25 Hz impulse frequency. For the high-intensity group, the stimulation intensity will be individually adjusted in the session before starting the high-intensity tVNS stimulation at home. Recommended daily usage is max. 4 hours, after which it automatically shuts off.
Monitoring
Participants are monitored over 12 weeks using a combination of questionnaires and ecological momentary assessment. This approach allows for a comprehensive assessment of the patient's health and well-being.
cardiowatch bracelet
The study employs the medically certified cardiowatch bracelet from Corsano (CE-MDR medical certification, FDA 510 (k) cleared) for continuous monitoring of vital signals, such as heart rate, heart rate variability, breathing rate, SpO2, physical activity and sleep.
