NCT06722677

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.

Outcome Measures

Primary Outcomes (1)

  • Upper Extremity Motor Section of the Fugl-Meyer Assessment (FMA-UE) Average Change

    The FMA-UE is a common scale used to measure motor impairment after a stroke. The range is 0 (more impairment) to 66 (no impairment). The FMA-UE will be analyzed for difference in average change at Clinic rehabilitation follow-up timepoint compared to Baseline follow-up timepoint (Difference in average change in FMA-UE from V3 to V4).

    V4, 6 weeks after Baseline follow-up timepoint

Secondary Outcomes (10)

  • Upper Extremity Motor Section of the Fugl-Meyer Assessment (FMA-UE) Response

    V4, 6 weeks after Baseline follow-up timepoint; V5, 6 weeks after Clinic rehabilitation follow-up timepoint

  • Upper Extremity Motor Section of the Fugl-Meyer Assessment (FMA-UE) Average Change

    V5, 6 weeks after Clinic rehabilitation follow-up timepoint; V6, 6 weeks after Home exercise follow-up timepoint

  • Wolf Motor Function Test (WMFT) Average Change

    V4, 6 weeks after Baseline follow-up timepoint; V5, 6 weeks after Clinic rehabilitation follow-up timepoint; V6, 6 weeks after Home exercise follow-up timepoint

  • Wolf Motor Function Test (WMFT) Response

The device can be set as active VNS or sham VNS (the actual intensity is 0 mA). An unmasking programmer not involved in treatments or assessments will be messaged the group of the participant and set appropriate stimulation setting at baseline follow-up timepoint. Other masking researchers, including therapists and assessors, as well as the participant will not know the stimulation setting.
