Abstract: Objective To evaluate the effect of transcranial direct current stimulation (tDCS) on post-stroke dysphagia. Methods Cochrane Library (CENTRAL), Medline, EMBASE, CBMdisc, VIP, CNKI and WANFANG Digital Journals were searched to collect randomized controlled trials (RCTs) about transcranial direct current stimulation for post-stroke dysphagia until February 2018. Two researchers independently screened literature, extracted data and evaluated the quality of the included studies. Then, meta-analysis was performed using RevMan 5.3 software.Results A total of eight RCTs were screened, including 225 patients. Compared to the control group, tDCS was effective on post-stroke dysphagia (SMD=0.71, 95%CI: 0.32~1.10, P<0.001) with safety.Conclusion tDCS could improve swallowing function of post-stroke dysphagia. Due to the limited quantity and quality of the included studies, more high quality studies are needed.
