What this trial studies

This pilot study aims to evaluate the acceptance, feasibility, and implementation of vagus nerve stimulation in female patients suffering from Long COVID. A total of 45 participants will be randomized into three groups to receive different frequencies of auricular vagus stimulation over a 12-week period. The study will assess various parameters of the autonomic nervous system and Long COVID symptoms through pre/post comparisons. Data will be collected at baseline, after 4 weeks, and after 12 weeks of treatment to evaluate the effects of the intervention.

Who should consider this trial

Good fit: Ideal candidates for this study are female patients aged 18-70 who have been diagnosed with Long COVID.

Not a fit: Patients with certain medical conditions such as malignancies, autoimmune diseases, or those with implanted devices like pacemakers will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a new therapeutic option for alleviating symptoms of Long COVID in female patients.

How similar studies have performed: While this approach is novel in the context of Long COVID, similar studies using vagus nerve stimulation have shown promising results in other conditions.
