Objective:To systematically evaluate the efficacy of repetitive transcranial magnetic stimulation (rTMS) or transcranial direct current stimulation (tDCS) in dysphagia after stroke.Methods:Six Chinese or English databases, including PubMed, Web of Science, Embase, CNKI, Wanfang and VIP, were searched by computer for randomized controlled trials of dysphagia after stroke with rTMS or tDCS (experimental group) from database construction to May 2023; those received conventional treatment+sham stimulation or conventional treatment only were enrolled as control group. Effective data were screened and extracted after literature quality evaluation by Cochrane. The outcome indexes included scores of penetration-aspiration scale (PAS), fiberoptic endoscopic dysphagia severity scale (FEDSS) and functional oral intake scale (FOIS). Reviewer Manager 5.4 software was used for Meta analysis of the extracted data, and mean difference ( MD) or standardized mean difference ( SMD) were used as effect indexes. Results:Twelve articles were finally included in the research literature, involving 637 subjects. Meta-analysis indicated that compared with the control group, the experimental group had significantly decreased PAS scores ( MD=-0.740, 95% CI: -1.020--0.460, P<0.001); FOIS scores in the experimental group were significantly increased compared with those in the control group ( MD=0.680, 95% CI: 0.220-1.130, P=0.003); FEDSS scores in the experimental group were significantly decreased compared with those in the control group ( SMD=-0.890, 95% CI: -1.110--0.670, P<0.001). Conclusion:The rTMS or tDCS can effectively alleviate dysphagia symptoms after stroke.
