ObjectiveThe purpose of this study was to conduct a Meta-analysis to assess the influence of physical therapy and respiratory muscle training on rehabilitation of patients with stable chronic obstructive pulmonary disease. To provide a basis for better rehabilitation exercise for patients, families, communities and hospitals.

MethodsAccording to the literature search strategy, the relative literatures of randomized controlled trials (RCTS) of physical therapy and respiratory muscle training on rehabilitation of patients with chronic obstructive pulmonary disease were searched in Cochrane Library、MEDLINE、Embase、CINAHL、CBM、Wan Fang、CNKI and VIP from January 1990 to October 2017. Languages are limited to Chinese and English.The literatures were screened according to the predefined inclusion and exclusion criteria by two people . Cochrane Handbook for Systematic Reviews of Interventions Version 5.1.0 were used to assess the quality of articles. The data were analyzed by Revman5.3.

ResultsA total of 7 articles were finally included, among of these 5 of which were written in English , Others were written in Chinese .They included 7 studies of randomized controlled trial and 267 patients with chronic obstructive pulmonary disease .7 studies show that treadmill exercise and respiratory muscle exercise are the most common rehabilitation methods.7 articles result of Meta-analysis showed that there were statistical differences between physical therapy and respiratory muscle training and other therapies in 6MWD、mMRC and FEV ₁%;More research is needed on the impact of other outcome measures.

ConclusionsPhysical therapy and respiratory muscle training is a reliable way of rehabilitation, it to the stabilization of COPD patients FEV ₁ % of expected value, activity ability, the influence of the degree of difficulty in breathing has a positive role.It is not stable for the positive effect of FVC and FEV ₁ .However, the effects of other outcome measures were not determined.
