Post-stroke constipation treated with acupoint embedding therapy: a multi-center randomized controlled trial / 中国针灸

ABSTRACT

OBJECTIVE@#To verify the clinical effect of acupoint embedding therapy on post-stroke constipation.@*METHODS@#The multi-central randomized controlled trial was adopted. 210 patients of post-stroke constipation were divided into an acupoint embedding group (105 cases, 4 cases dropped off) and a sham-embedding group (105 cases, 6 cases dropped off). In the acupoint embedding group, the acupoint embedding therapy was used at Tianshu (ST 25), Daheng (SP 15), Xiawan (CV 10), Zhongwan (CV 12), Qihai (CV 6), Guanyuan (CV 4) and Daju (ST 27). In the sham-embedding group, the sham-embedding therapy was given, in which, the acupoint selection, needle devices and manipulation were the same as the acupoint embedding group. But, no absorbable surgical suture was used in the needle tube. The treatment was given once every two weeks and 4 treatments were required in either group. It was to compare the weekly average complete spontaneous bowel movements (CSBMs) during treatment (from the 3rd to the 8th week) between the two groups, the weekly average spontaneous bowel movements (SBMs), Bristol stool form score (BSFS), the score of the patient assessment of constipation quality of life questionnaire (PAC-QOL) and the score of defecation difficulty before and after treatment.@*RESULTS@#The percentage of the cases with weekly average CSBMs ≥ 3 times in the patients of the acupoint embedding group was higher markedly than the sham-embedding group [91.1% (92/101) vs 43.4% (43/99), <0.01]. Compared with the values before treatment, the weekly average SBMs and BSFS scores after treatment were all increased obviously in the two groups (<0.01), and PAC-QOL score and the score of defecation difficulty were reduced remarkably (<0.01). After treatment, the increase range of SBMs and BSFS scores, as well as the decrease range of PAC-QOL score and the defecation difficulty score in the acupoint embedding group were all higher than the sham-embedding group respectively (<0.05).@*CONCLUSION@#The acupoint embedding therapy remarkably increases the spontaneous bowel movements, improves in feces form and defecation difficulty and strengthens the quality of life in the patients of post-stroke constipation.
