Asthma is a heterogeneous disorder with coughing, wheezing, shortness of breath, and chest tightness. People suffering from asthma have enlarged resistance of airways, along with lung hyperinflation and air trapping, which results in the impairment in inspiratory muscle and alterations in thoraco-abdominal mechanics. Physical therapy approaches can give better results. Inspiratory muscle training is non-pharmacological treatments that enhance asthma control with convenient easy and safe way. Objective: To find the effects of inspiratory muscle training on dyspnea and pulmonary function test in asthmatic patients. Methods: A quasi-experimental study was conducted on twenty four patients of asthma. Patients were assigned into either Inspiratory Muscular Training group or Conventional asthmatic rehabilitation group, both groups were treated for 6 weeks with 3 sessions per weeks. Bprg’s scale and Functional pulmonary assessment were used for analyzing the effects of treatment before and after the duration of 6 weeks. Data was analyzed by SPSS. 25. Results: The mean age of patients in group A and B was as respectively, 30.75 ± 7.26 and 30.25 ± 6.21 years. There was statistically significant difference between two groups with p value <0.05 on Borg scale. Dyspnea value decreased to greater extent in Group B with mean value 2.76 ± 0.58 as compared to Group A with mean 2.11 ± 0.86. Fatigue value decreased to greater extent in Group B with mean value 2.76 ± 0.58 as compared to Group A with mean 2.00 ± 0.80. The mean difference on pulmonary function test in inspiratory muscle group was greater as compared to other group. Conclusion: The study concluded that Inspiratory Muscle Training was more effective as compare to Conventional asthmatic rehabilitation in reducing dyspnea and improving pulmonary functional capacity.
