Vagus Nerve Stimulation for Stroke Rehabilitation
Does vagus nerve stimulation help with stroke rehabilitation? 37 human studies have investigated VNS for stroke rehabilitation, including 11 systematic reviews, 13 RCTs, and 8 controlled trials, published between 2016 and 2026, with 27 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.
