Design, Setting, and Participants
salvageable, cortical ischemia
This randomized clinical trial was sham controlled with 3 + 3 dose escalation design, and was conducted at a single center from October 2018 to July 2021. Eligible participants were treated for AIS within 24 hours from onset, had imaging evidence of cortical ischemia with salvageable penumbra, and were ineligible for reperfusion therapies. HD C-tDCS electrode montage was selected for each patient to deliver the electric current to the ischemic region only. Patients were followed for 90 days.
