Mechanism of deglutition stage acupuncture for treating deglutition disorder after stroke.

This research analyzed the efficacy of dysphagia after stroke and evaluated the clinical curative effect after treatment by the staging acupuncture method in comparison with traditional acupuncture method. We tried to study the curative effect of the staging acupuncture treatment after stroke and the possible mechanism of action. Then it could provide the basis of evidence-based medicine and lead for further research. There were 30 patients in the experimental group and the control group, including 15 patients at the middle oral stage and pharynx stage, respectively. The patients were divided into groups who met the standards according to the time sequence of hospitalization using the randomized controlled trial method. Comparing the curative effect between the experimental group control group after 12 days the therapeutic effect evaluation criteria were the water intake test score and the standard swallowing function score (SSA) score and recorded the occurrence of adverse events. There was no statistically significant difference (P>0.05) of oral and pharyngeal period in the baseline data between the two groups in gender, age, course of disease before treatment, and SSA scores before treatment. After treatment, there was statistically significant difference between the two groups. For dysphagia after stroke, the effect of acupuncture in deglutition stage was better than that in routine acupuncture group. Comparison of the efficacy between the oral and pharyngeal phases showed that the staged acupuncture group was superior to the traditional acupuncture group.
