| Abstract | This meta-analysis aimed to evaluate the effectiveness of nonpharmacological respiratory interventions in patients with pulmonary diseases. Specifically, it quantitatively assessed the impact of these interventions on pulmonary function (forced expiratory volume in 1 s [FEV₁], forced vital capacity [FVC], maximal inspiratory pressure [MIP], and maximal expiratory pressure [MEP]) and exercise capacity (6-min walk test [6MWT]) based on randomized controlled trials (RCTs). Methods: A total of 129 RCTs published over the past 10 years were initially identified from PubMed, Embase, and Cochrane Library. After applying the eligibility criteria, four studies were included in the final analysis. The effect sizes were calculated using the standardized mean difference (SMD), and a random effects model was applied considering inter-study heterogeneity. Subgroup analyses were performed by disease type, intervention method, and functional outcomes. Results: Significant improvements were found across all outcomes (FEV₁: SMD=0.28; FVC: SMD=0.25; MIP: SMD=0.31; MEP: SMD=0.29; 6MWT: SMD=0.34; all p<.001). Inspiratory muscle training (IMT) showed the greatest effect size (SMD=0.36), and the most consistent improvement was observed in patients with chronic obstructive pulmonary disease (SMD=0.34). The results of funnel plot visualization and Egger’s test (p=.557) indicated a low risk of publication bias. Conclusion: Nonpharmacological respiratory interventions are effective in improving pulmonary function and exercise capacity in patients with pulmonary diseases. IMT, pulmonary rehabilitation, and combined training modalities demonstrated high clinical utility. Future research should focus on standardized intervention protocols, long-term follow-up, and tailored approaches for high-risk populations. | ||
