Therapeutic Effects of Qigong in Patients with COPD: A Randomized Controlled Trial

Abstract

Conclusion: This study solidifies the concept that both HQG and PR produce positive effects on subjective symptoms and functions among COPD patients, and also provided evidence that HQG can induce additional effects compared to conventional PR.

Pulmonary Rehabilitation for Mild COPD: A Systematic Review

“…The corresponding authors were contacted to provide data on patients with mild COPD. Only Liu et al 18 made available the requested data, and therefore their study was included. The other 7 studies were excluded.…”

“…Results indicate that the quality of the studies varied among poor, 19 fair, 20 and good. 18 The 3 studies scored particularly poorly in the following items: description of adverse events, sample representativeness, patient and assessor blinding, adjustment for confounding factors in the analysis, and power. …”

“…The included studies had different designs that included retrospective, 19 one-group pretest-posttest, 20 and randomized controlled. 18 The 3 studies recruited a total of 100 patients receiving specialized care. Golmohammadi et al 19 did not provide data on age and gender ratio of the 31 patients with mild COPD.…”

“…Both programs included an educational component. Liu et al 18 implemented a homebased pulmonary rehabilitation program, consisting of 1 week of pursed-lip breathing and aerobic training under the supervision of health professionals followed by 6 months of peer-led walking and participation in ball games for 60 min twice a week. This study also had a control group that received standard medical treatment, consisting of health education and recommendations to exercise by themselves.…”

“…18,20 Significant improvements in exercise capacity were found when comparing pretest-posttest data (effect size (ES) 0.87) 20 and when comparing pulmonary rehabilitation with standard medical treatment (ES 1.82). 18 HRQOL HRQOL was measured in 2 studies using distinct instruments, that is, the St George Respiratory Questionnaire (SGRQ) 19 and the Zhongshan COPD questionnaire. 18 A small improvement in SGRQ symptoms (ES 0.34) and activity (ES 0.49) scores, and a medium improvement in SGRQ impact score (ES 0.66) were found after pulmonary rehabilitation.…”
