| Abstract |
Purpose : This study aimed to investigate the effects of inspiratory muscle training on pulmonary function, respiratory muscle strength, exercise capacity, dyspnea, and health-related quality of life in patients with COPD. Methods : The MEDLINE and PEDro databases were searched from September 1, 2019, to September 30, 2021. Three studies were included, with a total 41 subjects. The intervention methods consisted of inspiratory muscle training. Results : Results showed that, compared with the control group, inspiratory muscle training had a significant effect on maximum inspiratory pressures. However, there was no improvement in exercise capacity. Conclusion : Only inspiratory muscle training improved inspiratory muscle strength and pulmonary function. Both the pulmonary rehabilitation plus inspiratory muscle training group and the pulmonary rehabilitation group were compared but no significant difference was found in exercise capacity in patients with COPD. |
