Abstract: BACKGROUND: Transcranial direct current stimulation (tDCS) has a considerable advantage in the rehabilitation treatment of dysphagia. OBJECTIVE: The purpose of this study was to explore the effect of tDCS combined with respiratory training on dysphagia in post-stroke patients. METHODS: From December 2017 to January 2019, 64 post-stroke patients who were hospitalized in the Department of Neurology of the Second Hospital of Hebei Medical University were enrolled in this study. They were randomly divided into control and treatment groups (n= 32). Patients in the two groups received routine swallowing rehabilitation training and respiratory training. On this basis, the patients in the treatment group received tDCS. The anode was placed in the movement area of the pharyngeal cortex on the unaffected side of the patients’ bodies, and the cathode was placed in the upper orbital orbit on the opposite side. The current intensity was 1.5 mA, 20 min/time, 1 time/d, and 6 d/w. Before and after the treatment, the water swallow text, functional oral intake scale (FOIS), forced vital capacity (FVC) and peak expiratory flow (PEF) were assessed, and the correlation among them was evaluated. RESULTS: There were no differences in all indexes before and after treatment. After treatment, water swallow text, FOIS, FVC and PEF were all better than before treatment, and the clinical efficacy in the treatment group was significantly better than that in the control group. FVC and PEF were positively correlated with water swallow text and FOIS. CONCLUSION: tDCS combined with respiratory training may have a significant therapeutic effect on dysphagia in post-stroke patients.
