Abstract :Background: Specific breathing exercises are reported to improve quality of life and reduce symptoms; although no significant benefit on lung function or reduction of exacerbation risk. Additionally, inspiratory muscle training insert ignore into journalissuearticles values(IMT); aims to increase diaphragm and inspiratory muscle endurance. In this regard, IMT has been studied in uncontrolled asthma patients to investigate its effect on respiratory symptoms and pulmonary functions. Methods: Twenty-one uncontrolled and partially controlled asthmatic patients were included in the study. Asthma control test insert ignore into journalissuearticles values(ACT);, asthma quality of life questionnaire insert ignore into journalissuearticles values(AQLQ);, and spirometric evaluations were performed. The study population was randomized into two groups. The standard care group insert ignore into journalissuearticles values(n=10); received standard medical treatment while the intervention insert ignore into journalissuearticles values(n=11); group practiced a portable threshold IMT device following standard medical treatment. Results: The study was completed by 15 patients due to 6 lost follow up insert ignore into journalissuearticles values(one intervention group and 5 standard care); and one asthma exacerbation. We have found that the intervention group tended to have increased pulmonary function test parameters and AQLQ scores, moreover; MIP values and ACT scores have statistically significant increases after IMTinsert ignore into journalissuearticles values(p=0.01, p=0.02 respectively);. Conclusion: Add-on IMT to standard medical treatment could improve asthma control by strengthening inspiratory muscles in uncontrolled asthmatic patients. IMT could be considered in the non-pharmacological treatments of uncontrolled asthmatic patients. Despite the limited number of patients, this study revealed that IMT might have positive outcomes for uncontrolled asthma patients.
