Abstract:
Objective:To study the effect of transcranial direct current stimulation (tDCS) regulating excitability of the vagus nerve on dysphagia after stroke. Methods:From September, 2020 to February, 2021, 28 patients with dysphagia after stroke were randomly divided into control group (n = 14) and tDCS group (n = 14). Both groups accepted swallowing function training, and tDCS group received anodal tDCS over vagus nerve, while the control group received sham tDCS. They were assessed with modified Mann Assessment of Swallowing Ability (MMASA) and Australian Therapy Outcome Measures (AusTOMs)-swallowing scale before and after treatment. Results:The scores of MMASA (|t| > 5.593, P < 0.001) and AusTOMs swallowing scale (|Z| > 2.121, P < 0.05) increased in both groups after treatment, and were higher in tDCS group than in the control group (|t| = 2.439, |Z| = 2.079, P < 0.05). Conclusion:Anodal tDCS over vagus nerve may further release dysphagia after stroke.
