Abstract
Objective
To investigate the effects of combined respiratory muscle and exercise training on inspiratory muscle strength, exercise capacity, spirometry measurements, asthma control the quality-of-life in children with asthma.
Methods
Fifty children with asthma, who were treated in children’s hospital of Chongqing medical university in Chongqing between May and December 2021, were selected and randomly divided into a rehabilitation group and a control group by using a random number table. The control group was given routine drug treatment and health education while the rehabilitation group received a combination of respiratory muscle and exercise training on the basis of control group.
Results
After three months of treatment, the maximum inspiratory pressure, level of asthma control and quality-of-life in the rehabilitation group were significantly improved when compared with those in the control group (P<0.05); there were no significant differences in the 6-minute walking test and spirometry measurements (P>0.05). After three months of treatment, all outcome indicators in the rehabilitation group were significantly improved when compared to those before treatment (P<0.05). The mean value of maximum inspiratory pressure and some indices of spirometry measurements in the control group were significantly improved when compared to those before treatment (P<0.05).
Conclusion
Combining respiratory muscle and exercise training on the basis of the routine drug treatment and health education significantly improved inspiratory muscle strength, the level of asthma control and the quality-of-life in children with asthma. More research is needed to explore its role in asthma in the future.
