ABSTRACT
Objective:To evaluate the effectiveness of inspiratory muscle training in middle-aged and elderly patients with obstructive sleep apnea(OSA).Methods:The randomized controlled trials (RCT) on the effect of inspiratory muscle training in middle-aged and elderly patients with OSA were collected using the databases of PubMed, Embase, Cochrane Library, Web of Science, Chinese National Knowledge Infrastructure, Chinese Biomedical Literature Database and Wanfang database, the time was from the construction of the database to December 2020. The literature quality was evaluated and data were extracted from the included literature. RevMan5.3 software was used to analyze the collected data.Results:A total of 8 RCTs were included. Meta-analysis showed that inspiratory muscle training could reduce apnea hypopnea index(AHI)( P<0.05), Epworth Sleepiness Scale(ESS)( P<0.01) and Pittsburgh Sleep Quality Index(PQSI)( P<0.01), but had no effect on lowest oxygen saturation ( P>0.05). Conclusions:Inspiratory muscle training is a safe and feasible training method that can decrease AHI, ESS and PSQI in middle-aged and elderly patients with OSA.
ABSTRACT
Objective:To evaluate the effectiveness of expiratory muscle training in patients with chronic obstructive pulmonary disease.Methods:The randomized controlled trials (RCT) and controlled clinical trials (CCT) on the effect of expiratory muscle training in patients with chronic obstructive pulmonary disease were collected using the databases of PubMed, Embase, Cochrane Library, CNKI, CBM and Wanfang, time is from the construction of the database to November 2019. The literature quality was evaluated and data were extracted from the included literature. Data were analyzed with Revman5.3 software.Results:A total of 8 RCTs and 1 CCT were included. The Meta-analysis showed that Mean difference and its 95% confidence interval of P Imax, P Emax, FEV1, 6MWD and SGRQ score were 0.58 (-1.34, 2.51), 8.11 (-2.64, 18.86), -0.12 (-0.22, -0.01), -16.47(-40.76, 7.82), -1.52 (-3.75, 0.70) (all P>0.05, except for FEV1, P=0.03). Conclusions:In the pulmonary rehabilitation program of COPD patients, EMT combined with IMT does not achieve better results than IMT alone, it is recommended that we can only use IMT instead of EMT combined with IMT, and the same training effect will be achieved with less time and cost.
