This will be a randomized controlled trial Patients will be divided into two groups randomly. Both groups will receive postural drainage as baseline treatment thrice a week for two weeks. The intervention group will undergo additional Aerobic Training thrice a week for two weeks as well along with postural drainage. Aerobic training will include a 5-step stair-climbing and a 10-step walk during each session. Data will be collected before and at the end of two weeks. Respiratory Rate, Pulse Oximeter, 10-meter Endurance walk test, and Pediatric Cough Questionnaire will be used to collect data pre and post-treatment. Data will be analyzed by use of SPSS Version 2010. Data will be presented in the form of mean and standard deviation.

Chronic suppurative lung disease (csld) is a clinical syndrome in children with respiratory symptoms and signs. Children who have bronchiectasis symptoms but non-diagnostic scans are described as having chronic suppurative lung disease (csld). Postural drainage improves secretion clearance techniques, it is equally as effective as other airway clearance techniques. This study will focus on the implementation of postural drainage and aerobic training in this disease to find their effect on respiratory rate, oxygen saturation, and endurance.
