Short-Term External Trigeminal Nerve Stimulation for Acute Ischemic Stroke: A Sham-Controlled Trial

Sponsor: Xidian University

Summary

The goal of this clinical trial is to evaluate the efficacy of a 5-day short-course external trigeminal nerve stimulation (eTNS) regimen in patients with acute ischemic stroke. The main questions it aims to answer are whether a 5-day eTNS intervention can significantly improve the neurological response rate at Day 30 compared to sham stimulation, and whether this short-course treatment yields sustained improvements in neuropsychiatric symptoms (depression, anxiety, and insomnia) over a 90-day follow-up period. Researchers will compare the active eTNS group to a sham-controlled group to see if the 5-day stimulation provides a sustained neuroprotective effect. Participants will be randomly assigned (1:1) to receive either active eTNS or sham eTNS for 5 consecutive nights within 72 hours of stroke onset, in addition to standard medical therapy, and will undergo neurological and functional assessments (NIHSS, mRS, BI) at baseline (Day 0), Day 5, Day 30, Day 60, and Day 90, as well as complete neuropsychiatric questionnaires (PHQ-9, GAD-7, and ISI) during the follow-up visits to evaluate their mood and sleep quality. In addition, brain imaging data and blood samples will be collected at baseline (Day 0) and after the 5-day intervention (Day 5) for exploratory analyses of infarct volume and peripheral inflammatory markers.
