Abstract
Background: Lung hyperinflation in chronic obstructive pulmonary disease (COPD) patients leads to a decrease in chest wall flexibility, mobility, and compliance. These affect respiratory ventilation resulting in dyspnea and decreased exercise capacity.
Objective: To determine the effects of a home-based pulmonary rehabilitation program with chest wall compression using an elastic band during exhalation on lung function, functional exercise capacity, chest wall expansion, dyspnea and quality of life in patients with COPD.
Methods: Thirty-two men with stable moderate to severe COPD, aged 40 to 70 years, were randomly assigned to control and experimental groups. In the control group, participants performed a home-based pulmonary rehabilitation program, whereas the combination of home-based pulmonary rehabilitation program with chest wall compression was performed on the experimental group 3 times per week for 8 weeks. Lung function test, six-minute walk test (6MWT), upper and lower chest expansion, Modified Medical Research Council (MMRC) dyspnea score and COPD Assessment Test (CAT score) were measured at baseline and post-intervention.
Results: There was no significant difference in lung function. 6MWT, MMRC, and CAT were improved significantly in both control and experimental groups (p<0.001) after rehabilitation program but there were no significant differences between groups (p>0.05). Moreover, upper and lower chest expansions were significantly increased in the experimental group (p<0.001).
Conclusion: Chest wall compression with elastic band improved chest wall mobility in COPD patients. Although this program may not improve lung function, the trend showed the potential for improvement in dyspnea, functional exercise capacity, and quality of life.
