Background: Chronic Obstructive Pulmonary Disease (COPD) is a progressive disease characterized by airflow limitation / obstruction that is either not reversible or only partially reversible. Pulmonary rehabilitation is an accepted non-pharmacological intervention for individuals with COPD. But there is __ampersandsignlsquo;no consensus__ampersandsignrsquo; regarding the most favorable duration of pulmonary rehabilitation for patients with COPD. Objective: To determine the effects of a short term Pulmonary Rehabilitation programme on exercise capacity, forced vital capacity and Quality of life in chronic obstructive pulmonary disease. Methods: 30 mild-moderate COPD patients, who fulfill inclusion and exclusion criteria, were given conventional physical therapy and aerobic training for 5 days per week and continued for 4 weeks. 6 min walk distance; Forced vital capacity (FVC) and chronic respiratory questionnaire (CRQs) were taken at baseline before and after completion of rehabilitation program as outcome measures. Results: Results show statistically significant difference in 6 min walk distance (6 MWD), Dyspnea, Fatigue (p__ampersandsignlt;0.05). But no significant difference was found in FVC, Emotion and Mastery Conclusion: Through the study it has been observed that 6 MWD and CRQs shows more improvement whereas FVC shows no much improvement after 4 week of rehabilitation program. Hence it has been concluded that short term pulmonary rehabilitation is an effective and economical method for improving the exercise capacity and Quality of life but not similarly effective for FVC in patients with COPD.
