Key result
Pulmonary Daoyin improves 6-minute walking distance by ~25m and pulmonary function in COPD versus control.
Why the study?
Previous studies on the efficacy of pulmonary Daoyin in improving physical and psychological status and quality of life in COPD patients have yielded inconsistent results.
Does pulmonary Daoyin improve exercise ability, breathlessness, and pulmonary function in patients with COPD?
Meta-Analysis (n=1,732)
Does pulmonary Daoyin improve exercise ability, breathlessness, and pulmonary function in patients with COPD?
Effect estimate: MD 24.53 (95% CI 18.55, 30.52)
p-value: p=<0.00001
Pulmonary Daoyin may be an effective adjunctive rehabilitation exercise to improve exercise capacity, breathlessness, and pulmonary function in patients with COPD.
Supports pulmonary Daoyin as adjunctive COPD rehabilitation; extends meta-analytic evidence for traditional exercises on functional capacity.
Objective: Previous research has demonstrated that pulmonary Daoyin could be an efficacious way to ameliorate the physical and psychological state of sufferers with chronic obstructive pulmonary disease (COPD) and bolster the quality of life. However, the results are not consistent. Thus, the objective of this research is to assess the impacts of pulmonary Daoyin in individuals with COPD. Methods: Relevant articles were searched in Web of Science, Cochrane Library, PubMed, EMBASE, SinoMed, CNKI, Wanfang, and VIP from database inception to January 2024. Results: There were a total of 15 randomized controlled trials (RCTs) included in this meta-analysis involving 1732 patients, of which 864 participated in the intervention group and 868 in the control group. When comparing with the control group, the COPD patients practicing pulmonary Daoyin demonstrated a significant improvement in 6 min walking distance (mean difference [MD] = 24.53, 95% confidence interval [CI] [18.55, 30.52], P <0.00001), forced expiratory volume in the 1 s (FEV 1 ) (MD = 0.39, 95% CI [0.18, 0.59], P = 0.0002), percentage of FEV 1 to the predicted value (FEV 1 %) (MD = 5.35, 95% CI [3.22, 7.48], P < 0.0001), the forced vital capacity (FVC) (MD = 0.39, 95% CI [0.06, 0.73], P = 0.02), percentage of FVC to the predicted value (FVC%) (MD = 7.52, 95% CI [4.91, 10.13], P < 0.00001), the ratio of FEV 1 /FVC (MD = 4.95, 95% CI [0.91, 8.99], P = 0.02), peak expiratory flow rate (standardized MD = 0.98, 95% CI [0.74, 1.22], P < 0.00001), modified Medical Research Council (mMRC) scale (MD= −0.47, 95% CI [−0.89, −0.04], P=0.03), and Borg scale (MD =−0.65, 95% CI [−0.75, −0.55], P < 0.00001). Conclusions: Our findings may illuminate the influence of pulmonary Daoyin on exercise ability, breathlessness, and pulmonary function in COPD patients. More rigorous RCTs with larger samples and longer-term interventions will be required moving forward.

Chen et al. (2024) conducted a meta-analysis in Chronic obstructive pulmonary disease (COPD) (n=1,732). Pulmonary Daoyin vs. Control group was evaluated on 6 min walking distance (MD 24.53, 95% CI 18.55, 30.52, p=<0.00001). Pulmonary Daoyin significantly improved 6-minute walking distance (MD 24.53; 95% CI 18.55-30.52; P<0.00001) and pulmonary function in patients with COPD compared to control.
