Abstract :

Background: Inspiratory muscle weakness is a clinical feature in patients with COPD. Due to hyperinflation, the shortened diaphragms generate lower force during contraction, contributing to dyspnea and reduced exercise tolerance. Due to pathological changes the strength of inspiratory muscle is reduced which leads to early fatigue and reduce in functional capacity. Therefore, inspiratory muscle training in COPD patients is designed to enhance respiratory muscle function and to reduce the severity of breathlessness and improve exercise tolerance.Objective: To study the effect of the Breather device on inspiratory muscle strength and functional capacity by measuring Maximum Inspiratory Pressure (Pimax) and 6 Minute Walk Distance (6MWD).Methodology: Thirty participants both male and female diagnosed with COPD were included in the study and were divided into two groups. Baseline assessment was done using Pimax and 6MWD. Participants in group A performed inspiratory muscle training by using breather device and diaphragmatic breathing and group B performed diaphragmatic breathing exercise twice a day for 2 weeks. Reassessment was done and data was compared. Results:There was a highly significant (p=
