Objective To summarize the evidence of pulmonary rehabilitation exercise in COPD patients, and to pave the way for the development of evidence-based pulmonary rehabilitation programs. Methods Computerized search in such websites and databases as the National Guideline Clearinghouse (NGC), the Scottish Intercollegiate Guidelines Network (SIGN), the American Thoracic Society（ATS）, British Thoracic Society (BTS), JBI Evidence-Based Health Care Database, Cochrane Library, PubMed, etc., was performed to retrieve literature on pulmonary rehabilitation exercise in COPD patients, which included guidelines, expert consensus statements, evidence summary reports, systematic reviews, and randomized controlled trials. Results A total of 35 publications were included, resulting in the formation of 21 pieces of best evidence, which embraces 10 themes(indicated population , timing of pulmonary rehabilitation exercise, places to practice pulmonary rehabilitation exercise, assessment of patients, exercise prescription, duration of exercise programs , quality control, other ways of exercise, health education, effect evaluation ). Conclusion The evidence summary of best practice for pulmonary rehabilitation in patients with chronic obstructive pulmonary disease is inclusive. Medical and health care workers can select practical evidence tailored to the actual situation, in an effort to promote patient health.
