Background Transcranial direct current stimulation (tDCS) may have a potential for improving post-stroke dysphagia. Objective The purpose of this study was to examine the effect of tDCS on improving dysphagia in stroke patients. Patients and methods Forty stroke patients were divided randomly into two equal groups (the study (group A) and control groups (group B). Group A received a physical therapy program and active (tDCS), and group B received the same physical therapy program and sham (tDCS). The Dysphagia Outcome and Severity Scale (DOSS) and videofluoroscopy were performed in all patients before and after 2 weeks of the treatment program. Results Before treatment, there were no significant differences between the two groups for DOSS score or digital fluoroscopic findings. After treatment, there were significant differences between the study and control group for DOSS score and digital fluoroscopic findings. Conclusion Anodal tDCS is effective in improving dysphagia in stroke patients.

经颅直流电刺激（tDCS）：对改善脑卒中患者吞咽困难的作用

背景 经颅直流电刺激 (tDCS) 可能具有改善卒中后吞咽困难的潜力。目的 本研究的目的是检查 tDCS 对改善脑卒中患者吞咽困难的影响。患者和方法 40 名脑卒中患者随机分为两组（研究组（A 组）和对照组（B 组）。A 组接受物理治疗方案和活动（tDCS），B 组接受相同的物理治疗方案和假手术（tDCS）。所有患者在治疗前和治疗后 2 周进行吞咽困难预后和严重程度量表（DOSS）和视频透视检查。结果治疗前，两组在 DOSS 评分或数字上无显着差异。透视结果。治疗后，在 DOSS 评分和数字透视结果方面，研究组和对照组之间存在显着差异。结论阳极tDCS可有效改善脑卒中患者吞咽困难。
