OBJECTIVE: To determine and compare the effects of Theraband exercises with incentive spirometer exercise in improving respiratory muscle strength among bronchial asthma. METHOD(S): In this study, 30 Individuals with Bronchial asthma were taken and assessed for FEV1/FVC, maximum voluntary ventilation (MVV) using a computerized spirometer, dyspnea level graded using MMRC scale and diaphragm muscle strength assessed using manual muscle testing (MMT) as pre-test then the individuals were randomly allocated in two groups: group A and group B. Group A (n = 15) received Theraband exercise and group B (n = 15) were treated with incentive spirometer for a total period of 4 w following which the outcome measures were repeated for post-test. RESULT(S): Based on the obtained statistics, both the groups showed significant improvement within groups when comparing pre and post-test measures. On comparing the mean values of the post-test between the groups, Theraband exercises showed clinically higher significant results than incentive spirometer exercises. CONCLUSION(S): From the result, it shall been concluded that both Theraband exercises and incentive spirometer exercises shows improvement in MVV, FEV1/FVC, reduced dyspnea and increased respiratory muscle strength. Hence, Theraband exercises are effective compared to the incentive spirometer.
