A Trial of Rehabilitation Paired With VNS for Motor Function in Patients With Stroke (Repair Study)

Brief Summary

The goal of this clinical trial is to investigate the efficacy and safety of vagus nerve stimulation (VNS) paired with rehabilitation for enhancing upper extremity motor function after ischemic stroke. Researchers will compare the outcomes of active VNS paired with rehabilitation against sham VNS (the actual intensity is 0 mA) also paired with rehabilitation, in order to assess improvements in arm motor function post-stroke. Participants in this study will undergo a surgical procedure to implant the VNS system and will subsequently recieve a 6 weeks in-clinic therapy, followed by an additional 6 weeks home exercise. During the final 6 weeks, participants will either recieve in-clinic therapy or maintain their home exercise, depending on their assigned group.
