Effect of TDCS Combined with Intraoral Electrical Stimulation

Objective: To investigate the clinical efficacy of transcranial direct current stimulation (tDCS) combined with intraoral electrical stimulation in patients with dysphagia after pontine infarction. Methods: This prospective study enrolled a total of 90 patients with dysphagia due to pontine infarction from October 2022 to November 2024, and they were divided into three groups according to the treatment method: control group A, control group B, and experimental group C. Control group A was given intraoral induction electrical stimulation, control group B was given transcranial direct current stimulation (tDCS), and experimental group C was given tDCS combined with intraoral induction electrical stimulation. The three groups were compared in terms of efficacy, modified Waffield Drinking Water Test Score (MWST), Penetration-aspiration scale (PAS), Functional Oral Intake Scale (FOIS), Hyoid-Larynx Complex mobility, maximum amplitude of surface electromyography, and swallowing time.
