Effects Of Transcutaneous Electrical Acupoint Stimulation On Patients With Chronic Obstructive Pulmonary Disease:a Meta-analysis

Objective:To evaluate the effects of Transcutaneous Electrical Acupoint?acu-TENS?on chronic obstructive pulmonary disease.Methods:We searched Chinese and English databases such as embase,pubmed,cochrance library,Wanfang Data Knowledge Service Platform?WanFang?,VIP Consulting Chinese Journal Service Platform?VIP?,China Biomedical Document Service System?CBM?,China Knowledge Network?CNKI?,etc.The retrieval time is from the time of database construction to March 1,2018.Searching for randomised controlled trials of percutaneous acupoint electrical stimulation for chronic obstru-ctive pulmonary disease.For documents that meet the criteria for inclusion and exclusion,quality assessments are conducted in strict accordance with the quality assessment tools recommended by Cochrane Collaboration.We used Review Manager5.3 to perform cumulative meta-analysis of the outcomes of the included literature,use forest maps,and further analyze the effect of transcutaneous acupoint electrical stimulation on lung function and quality of life in patients with chronic obstructive pulmonary disease.Result:A total of 6 articles on the acu-TENS treatment of chronic obstructive pulmonary disease were included in this study,including 6 randomized controlled trials with a total of 253 patients with chronic obstructive pulmonary disease treated with acu-TENS.The results of the meta-analysis were:6-minute walk test[MD=14.25,95%CI?10.76,17.73?,p<0.00001];visual analog scale for dyspnea[MD=-12.00,95%CI?-12.14,-11.86?,p<0.00001];FEV₁[MD=0.13,95%CI?0.11,0.14?,p<0.00001];FVC[MD=0.02,95%CI?0.01,0.06?,p=0.15];PEF[MD=0.80,95%CI?0.53,1.07?,p<0.00001];FEV₁%pre[MD=4.52,95%CI?2.96,6.07?,p<0.00001];FVC%pre[MD=0.73,95%CI?-0.28,1.74?,p=0.16].Compared with the sham-stimulated control group,the 6-minute walking distance,visual analog scale of dyspnea,FEV₁,PEF,and FEV₁%pre were significantly improved in the acu-TENS-treated group compared with the sham-stimulated control group,whereas FVC and FVC%pre were improved.No statistical significance.Conclusion:Transcutaneous electrical acupoint stimulation can improve partial lung function and quality of life in patients with chronic obstructive pulmonary disease.
