Objective To observe the clinical therapeutic effect on post-stroke dysphagia treated with He's santong(triple promotion) acupuncture therapy through surface electromyography(sEMG). Methods A total of 60 patients with post-stroke dysphagia were divided into a routine treatment group and a He's santong acupuncture therapy group

using blocked randomization

30 cases in each one. In the routine treatment group

the secondary prevention and swallowing rehabilitation training were adopted. In the He's santong acupuncture therapy group

on the base of the treatment as the routine treatment group

weitong(mild promotion

the score of swallowing grading scale

the score of the modified Mann assessment of swallowing ability(MMASA) and the peak amplitude of sEMG were recorded before and after treatment in patients. Results Compared with before treatment

the score of FEES and PAS after treatment was decreased(P<0.05)

the scores of swallowing grading scale and MMASA after treatment were increased in both routine treatment group and He's santong acupuncture therapy group(P<0.05)

the peak amplitude of sEMG was increased(P<0.05) in the He's santong acupuncture therapy group and decreased(P<0.05) in the routine treatment group. Compared with the routine treatment group

the score of FEES and PAS was decreased(P<0.05)

the scores of swallowing grading scale and peak amplitude of sEMG were increased in the He's santong acupuncture therapy group(P<0.05). Conclusion He's santong acupuncture therapy is obviously effective on post-stroke dysphagia

which may be related to its effects in increasing the contraction of swallowing-related muscles and improving the peak amplitude of hyoid muscle group.
