Purpose:
Pursed lip breathing (PLB) and diaphragmatic
breathing (DB) are breathing techniques frequently adopted
by patients with COPD. We conducted this systematic
review to investigate the effects of PLB plus DB exercise on
pulmonary function and exercise capacity in COPD patients.
Methods:
A comprehensive literature review was
conducted by collecting all relevant studies published
before November 30, 2017 in English and Chinese, through
PubMed, EMBASE, the Cochrane Library, China National
Knowledge Infrastructure (CNKI), Wanfang database, and
VIP database. Mean difference (MD) or standardized mean
difference (SMD) with 95% confidence interval (CI) was
calculated after data combination. Heterogeneity between
the studies was assessed by Cochran’s Q test and I2 statistics.
Results:
A total of 15 RCTs involving 1098 participants (570 in
treatment groups and 528 in control groups) were included.
Significant improvements were found in forced expiratory
volume in one second (FEV1) (SMD=0.47, 95% CI: 0.27-0.67,
P<0.0001), forced vital capacity (FVC) (SMD=0.87, 95% CI:
0.59-1.15, P<0.0001), FEV1 as a proportion of FVC (FEV1/FVC)
(MD=8.30, 95% CI: 1.17-15.43, P=0.02), and 6-minute walk test
(6MWT) distance (MD=29.09, 95% CI: 19.35-38.83, P<0.0001).
Conclusion:
PLB combined with DB exercise effectively
promotes pulmonary function and exercise capacity
in patients with COPD, which might be useful for self-
management and pulmonary rehabilitation in COPD
