A COMPARATIVE STUDY BETWEEN BREATHING RETRAINING THERAPY AND PURSED LIP BREATHING FOR IMPROVING EXERCISE CAPACITY OF EMPHYSEMA PATIENTS

Aim To compare the effects of Breathing retraining therapy(BRT) and Pursed lip breathing(PLB) for improving Exercise capacity of Emphysema patients Materials and methods: Sixty patients with moderate emphysema were recruited for this study. The samples were chosen based on the practical sampling strategy. Randomly chosen two groups were designated as the BRT and PLB group, and they underwentBreathing retraining therapy and Pursed lip breathing at levels ranging from 20% to 55% of their maximum inspiratory and breathing capacities. Both groups were given instructions and exercise three days a week for eight weeks in addition to their prescribed medications. Results: Both the BRT and PLB groups experienced significant improvements in forced expiratory volume in the first second (FEV1) and 6minute walk Distance(6MWD). Each group showed a significant improvement over the 6-minute walking distance. Conclusion: In order to improve the pulmonary function test (PFT), exercise capacity, and 6-minute walking distance (6MWT), pulmonary rehabilitation programmes must incorporate both BRT and PLB.
