Summary
This study tested a device that sends mild electrical pulses to the ear to stimulate the vagus nerve, aiming to reduce pain and inflammation in people with erosive hand osteoarthritis, a painful and hard-to-treat arthritis. 148 adults with this condition used either the active device or a sham (inactive) device for 12 weeks. The main goal was to see if the active device reduced hand pain more than the sham.
