Vagus Nerve Stimulation for Rheumatoid Arthritis
Does vagus nerve stimulation help with rheumatoid arthritis? 9 human studies have investigated VNS for rheumatoid arthritis, including 3 RCTs, 3 controlled trials, and 1 observational study, published between 2014 and 2026, with 6 published since 2022. Studies use implanted (iVNS) and transcutaneous auricular (taVNS) stimulation. Findings vary by study design and population; the studies below are ranked by evidence strength so you can weigh the research directly.
