What this trial studies

This study investigates the effects of transcutaneous auricular vagus nerve stimulation (taVNS) on chronic upper extremity pain in stroke survivors. Up to 20 participants who have experienced a stroke at least six months prior will be recruited to assess the safety and feasibility of taVNS as a non-invasive pain management technique. Participants will undergo pain assessments before and after a 30-minute session of either active or sham stimulation to evaluate changes in pain perception. The study aims to establish taVNS as a viable option for alleviating post-stroke pain.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-80 who have experienced an ischemic or hemorrhagic stroke at least six months prior and suffer from right upper extremity pain.

Not a fit: Patients with a history of uncontrolled psychiatric disorders, severe hypertension, or those who are pregnant may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a new, non-invasive method for managing chronic pain in stroke survivors.

How similar studies have performed: Previous studies have shown that taVNS is safe and feasible in various populations, suggesting potential for success in this specific application.
