Effectiveness of Inspiratory muscle training using Ultrabreathe on Pulmonary function in Duchenne Muscular Dystrophy

Background: Individual with Duchenne Muscular Dystrophy are more prone for respiratory dysfunction. And thus the leading cause for death DMD. Objective: To find the effectiveness of inspiratory muscle training using ULTRABREATHE on pulmonary function in Duchenne Muscular Dystrophy. Methodology: The quasi experimental study was done in 5 Duchenne Muscular Dystrophy children as one group of age ranging from 9 to 16 years in wheelchair bound stage and they have been given for an ULTRABREATHE as an inspiratory muscle trainer for duration of six weeks. Outcome Measures: Pulmonary Function Test was analyzed using spirometry. Results: Statistical analysis shows, the mean and standard deviation value is 1.5380 and .84736 in pretest and the mean and standard deviation is 1.71 and .88752 with respect to tidal volume which shows significant improvement at p value> 0.038, whereas the other components like Duration of Inspiration, Total Lung Volume/Inspiration Time, Total Lung Volume, Inspiratory Capacity, Inspiration Time/Respiration Time, Forced Vital Capacity and Forced Expiratory Volume in One second (FEV1) not showed an significant improvement. Conclusion: The study concluded that the Effectiveness of inspiratory muscle training using ULTRABREATHE on pulmonary function in Duchenne Muscular Dystrophy children showed improvement only in Tidal Volume whereas all other components not showed a significant improvement.
