Systematic reviewBalance Impairment and Effectiveness of Exercise Intervention in Chronic Obstructive Pulmonary Disease—A Systematic Review
Section snippets
Data sources and searches
Literature search was conducted by 2 independent reviewers. Four electronic databases (Scopus, CINAHL, PubMed, Cochrane Library) were searched from their inception to June 30, 2019. Both reviewers limited search terms that included “COPD,” “COAD,” “CAL,” “Chronic obstructive pulmonary disease,” “Chronic obstructive airway disease,” “Chronic airflow limitation,” “postural control,” “balance,” “base of support,” “center of mass,” “center of pressure,” “stability limits,” “postural response,”
Results
A total of 3661 studies were found on initial electronic search. After removing the duplicates (n=1343), 2318 studies were included for title and abstract screening. Of these, 2299 studies were excluded due to irrelevant balance outcome studies (n=2292) (ie, cross-sectional studies=2105, interventional studies=175, systematic reviews and meta-analyses=12), using language other than English (n=2), and nonrandomized interventional study design (n=5). Finally, 19 studies were included in this
Discussion
This systematic review investigated impaired postural control in people with COPD. In addition, this review further evaluated the effects of exercise intervention on balance performance in this population. Overall, the findings of this review suggest that people with COPD have significant balance impairment than those without COPD as measured by a variety of balance tests (ie, functional, systematic, quantitative laboratory tests). There has been limited evidence for benefits of exercise
Conclusions
People with COPD have balance impairment assessed by various balance measures including functional, systematic, and quantitative laboratory tests. The available evidence suggests that balance training as part of PR program, Tai Chi, and cycling exercise may be effective in improving balance performance. Future research focusing on the effectiveness of exercise interventions on balance performance in people with COPD is still required. Nevertheless, this review highlights impaired balance in
