<br/><br/> Objective: To assess the effect of respiratory muscle training on pulmonary functions of chronic obstructive pulmonary disease patients. Design: Sixty men (40-60 yrs old)  with Chronic Obstructive Pulmonary Disease (COPD) were enrolled for this study. They were assigned randomly with 30 patients allocated to the control group and another 30  patients  allocated to the study group. The control group received a conventional chest physiotherapy in addition to medical treatment, whereas the study group received the same program in addition to respiratory muscle training using powerlung device. Both groups received the treatment sessions three times per week for 3 successive months. Measurement of ventilatory function and respiratory muscle Strength by using the spirometry and the COPD Assessment Test (CAT) was done before and after the 3 month intervention period. The data concerned with the ventilatory functions included forced vital capacity (FVC), forced expiratory volume in one second (FEV1), FEV1/FVC ratio, peak expiratory flow rate (PEFR), peak inspiratory flow rate (PIFR) , maximum voluntary ventilation (MVV) , maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP). Results: Each group demonstrated significant improvements in pulmonary function and respiratory muscle Strength after treatment, with significantly greater improvements seen in the experimental group when compared with the control group
