Primary outcomePrimary: Thermal Pain Threshold — 41.84; 42.51 Celsius

Summary

The purpose of this study is to explore whether a non-invasive form of ear stimulation called transcutaneous auricular vagus nerve stimulation (taVNS) can change the way participants perceive pain. Investigators will recruit up to 20 participants with chronic post-stroke upper extremity pain. The goal is to determine if there is a pain reduction after ear stimulation.
