Effect of inspiratory muscle training on pulmonary function of patients with asthma:a meta-analysis
Objective:To systematically evaluate the effect of inspiratory muscle training on lung function in pa-tients with bronchial asthma(asthma).Methods:PubMed,Cochrane Library,EMBASE,CNKI,Wanfang Data,VIP and other databases were searched for the randomized controlled trials(RCT)about inspiratory muscle training on pulmonary function of patients with asthma from inception to July 2023.Two researchers independently screened the literature,extracted data,evaluated the risk of bias of the included literature according to the Cochrane Hand-book,and then performed Meta-analysis using RevMan 5.3 software.Results:A total of 7 literatures were includ-ed,including 229 subjects.The results of meta-analysis showed that,compared with the control group,inspiratory muscle training effectively improved forced vital capacity of predicted value(MD=10.86,95％CI 4.34 to 17.38,P=0.001),peak expiratory flow(MD=98.47,95％CI71.76 to 125.19,P＜0.00001),maximal inspiratory pres-sure(MD=26.21,95％CI 1.71 to 50.72,P=0.04)and maximal expiratory pressure(MD=21.67,95％CI 5.50 to 37.85,P=0.0009).There were significant differences between two groups.Conclusion:Inspiratory muscle training can effectively improve the strength of respiratory muscles in patients with asthma,and can significantly im-prove some indexes of pulmonary ventilation function.
