BACKGROUND Rehabilitation from bronchiectasis is an easy process, which involves a dedicated multidisciplinary team of professionals and full participation of the patient. Acapella is a hand held device which incorporates two therapies, positive expiratory pressure and vibration, enabling the patients to clear their congested lung and airways. Early chest physical therapy can prevent several complications and also help the patients to gain independence and return to an active life style. We wanted to compare the effectiveness of Acapella and chest physical therapy. MATERIALS AND METHODS This is a randomized control trial involving 50 patients affected with bronchiectasis attending the pulmonary medicine department, Sri Ramachandra Institute of Research and Higher Education between April 2017 and April 2018. 50 patients suffering from bronchiectasis were included in this study and they were randomized by software and grouped into two groupsgroup 1 and group 2. Group 1 included patients treated with chest physical therapy and group 2 included patients treated with Acapella. The sample size was taken for convenience. RESULTS The results of the study show that Acapella and chest physical therapy has no significant difference in airway clearance. Both are effective. Acapella and chest physical therapy were compared using Mann Whitney test by using the parameter PPS, volume of sputum day 1, 2 and 3 and Average PEFR. P < 0.05-statistically significant. CONCLUSION The usage of Acapella and chest physical therapy shows no significant difference. Both are effective in airway clearance. Chest physical therapy can be performed in hospital setup by a respiratory therapist or a health care provider, whereas Acapella can be used in home care management for airway clearance by the patient himself with or without the assistance of family members.
