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.
