Systematic review and Meta analysis on the effectiveness and safety of tuina in treatment of functional constipation

OBJECTIVE To review systematically the effectiveness and safety of tuina (Chinese massage)in treatment of functional constipation. METHODS The articles on functional constipation treated with tuina were collected by computer retrieval from 7 databases from the date of establishment to March 28, 2020, including Chinese biomedical literature database (SinoMed), China journal full-text database (CNKI), full-text database of Wanfang academic journals (Wanfang), VIP Chinese science and technology journal database(VIP), PubMed, Dutch medical literature database (EMbase) and the Cochrane Library. After data extraction and quality evaluation of the included articles, Meta analysis was conducted with RevMan5.3 software. RESULTS A total of 16 articles were included, with 1424 cases involved. Meta analysis results showed: ①The total effective rate in the treatment group was higher than that in the control group (RR=1.28, 95%CI: 1.16-1.42, P<0.000 01). ②The effective rate for the symptoms of functional constipation in traditional Chinese medicine in the treatment group was higher than that in the control group (RR=1.38, 95%CI :1.25-1.52, Z=6.31, P<0.000 01). ③Adverse reactions in the treatment group in the treatment of functional constipation were less than those in the control group (RR=0.10, 95%CI: 0.02-0.49, Z=2.81, P=0.005).④The effective rate of functional constipation treated on the base of syndrome differentiation in the treatment group was higher than that of the control group (RR=1.50, 95%CI: 1.08-2.10, Z=2.39, P=0.02).⑤The improvements in fecal characteristics, defecation time and defecation frequency of the patients with functional constipation in the treatment group were better than those in the control group (P<0.05). CONCLUSION Tuina therapy presents a certain advantages on its curative effect on functional constipation, has less adverse reactions and relieves the relevant symptoms of functional constipation. But more randomized controlled trials with high quality and large sample are required to provide further verification of its effect.
