This research of randomized clinical trial will evaluate the effects of breather device and incentive spirometer on dyspnea, lung function and quality of life in COPD patients by taking sample of 80 patients through non probability convenience sampling as per inclusion criteria. The patients will be allocated randomly into two groups. One group will receive breather device 2 sets of 10 breaths two times a day ,6 days a week for 2 weeks. While second group will receive incentive spirometer 20 minutes per session 30 breaths per set 5-6 times a day for 2 weeks. The patient will be asked to hold breath in for 2-3 seconds. Outcomes including Modified Medical Research Council (mMRC) Dyspnea Scale, COPD Assessment Test (CAT) and 6-minute walk distance will be assessed at baseline and after the intervention period. The data will be analyzed by using SPSS
