Benefits of Inspiratory Muscle Training in COPD Patients

Background: Chronic Obstructive Pulmonary Disease (COPD) is a primary lung disease .The hyperinflation induces increased strain on the respiratory muscles, which are forced to work in a limited range of movement with negative pressure/effort relationship, leading to fatigue and increased dyspnoea. So purpose of this study is to assess the effect of Inspiratory Muscle Training on PImax and 6 Minute Walk Distance (6MWD).Objective: To assess the effectiveness of inspiratory muscle training on inspiratory muscle performance (PImax) & Exercise capacity in COPD. Materials and Methods: An Interventional study was conducted on 40 COPD patients having mild to moderate severity, to assess the pre and post differences in PImax, and 6MWD by applying inspiratory muscle training. Result: Statistical analysis showed that there is significant improvement in all outcomes after application of inspiratory muscle training. Conclusion: It can be concluded from the present study that Inspiratory Muscle Training has significant effect on PImax and 6MWD in COPD patients.
