Vagus Nerve Stimulation for Multiple Sclerosis
Does vagus nerve stimulation help with multiple sclerosis? 13 human studies have investigated VNS for multiple sclerosis, including 1 systematic review, 2 RCTs, and 7 controlled trials, published between 2005 and 2025, with 7 published since 2022. Studies use transcutaneous auricular (taVNS) and implanted (iVNS) stimulation. Findings vary by study design and population; the studies below are ranked by evidence strength so you can weigh the research directly.
