| Objective: To comprehensively evaluate the therapeutic effect of neuromuscular electrical stimulation on dysphagia after stroke. Methods： This study searched the Cochrane Library, PubMed, Medline, WOS core collection, CINAHL, EMbase, OCLC, ProQuest, CNKI, Wanfang, VIP, and CBM about randomized controlled trials (RCT) of the treatment of neuromuscular stimulation on dysphagia after stroke. Cochrane Handbook version 5.1.0 was used to assess trial quality and RevMan 5.3 was used to analyze meta data. Results： A total of 46 RCT were included in this study. There were 30 articles about neuromuscular electrical stimulation with swallowing training vs. swallowing training only, and swallowing function score was used as the outcome measure. The meta analysis showed that SMD=0.60, 95%CI=0.11-1.09 (P< 0.05). There were 7 articles about neuromuscular electrical stimulation with swallowing training vs. swallowing training only, and effective rate was used as the outcome measure. The meta analysis showed that OR=0.21, 95%CI=0.13-0.35 (P<0.05). There were 4 articles on neuromuscular electrical stimulation vs. swallowing training, and the swallowing function score was used as the outcome measure. The meta analysis showed that SMD=0.04, 95%CI=-0.19-0.26 (P>0.05). There were 3 articles on the neuromuscular electrical stimulation vs. acupuncture, and swallowing function score was used as the outcome measures. The meta analysis showed that SMD=0.52, 95%CI=-0.21-1.26 (P>0.05). There were 3 articles on neuromuscular electrical stimulation vs. electroacupuncture, and the swallowing function score was used as the outcome measures. The meta analysis showed that SMD=0.45, 95%CI=-0.31-1.22 (P>0.05). There were 2 articles about neuromuscular electrical stimulation vs. myoelectric feedback, and swallowing function score was used as the outcome measure. The meta analysis showed that SMD=0.77, 95%CI=-0.05-1.58 (P＞0.05). Conclusion： There is a statistically significant difference between the swallowing training combined with the neuromuscular electrical stimulation therapy and the swallowing training only. There is no statistically significant difference between the neuromuscular electrical stimulation with swallowing training, the acupuncture, the electroacupuncture, or the electromyographic biofeedback respectively. |
