Introduction: Pulmonary hyperinflation is critical factor in COPD patients which puts diaphragm at mechanical disadvantage. Shape and geometry of chest wall is altered in patients with COPD, consequently reduces opposing zone of
diaphragm. Low, flat diaphragm weakens diaphragm muscle & decreases the diaphragm function. This study was designed to investigate effect of Controlled Diaphragmatic Breathing on pulmonary function & 6Minute Walk Distance in stable mild to moderate severity COPD patients.
Method: Subjects were evaluated at the start of treatment & reevaluated after 3 weeks. 6 MWD & PFT pre & post treatment was done as per Standardized guidelines of ATS. The subjects received breathing retraining six days a week for
20 minutes for 3 weeks.
Result: Subject showed significant improvement in 6 MWD1 (t =2.301 ,P
