Overview

The study is a double-blind randomized controlled trial, lasting for 15 days for each participant. Patients with post-stroke dysphagia who receive treatment at the Rehabilitation Department are selected as the study subjects. The patients are randomly assigned to either the experimental group or the placebo group. All patients receive routine rehabilitation therapy and swallowing rehabilitation training, along with enteral nutrition support using Intermittent Oro-esophageal Tube. In addition to these interventions, patients in the experimental group receive transcranial direct current stimulation, while the instruments used for patients in the placebo group only illuminate an indicator light without any actual effect.
