The aim of this study was to collect and analyze clinical studies on electro-acupuncture therapies of post-stroke dysphagia to suggest the methods of the study about electro-acupuncture therapy. In this study, electronic searches were performed with searching sites. Searched words such as ‘중풍’, ‘뇌졸중’, ‘연하장애’, ‘전침’, ‘stroke’, ‘dysphagia’, ‘deglutition disorders’, ‘electro-acupuncture’ were used as a single keyword or in combinations. Through searching, 27 studies were selected and analyzed. In comparison of results before and after electro-acupuncture treatment, there were statistically significant improvement in 26 studies by using assessment such as video fluoroscopy swallowing study, swallowing water function test. The study of electro-acupuncture treatment for post-stroke dysphagia needs to be standardized and high-quality study models should be introduced.
