The aim of this study was to compare the effects of expiratory muscle training (EMT) and incentive spirometry (IS) in addition to conventional pulmonary rehabilitation after colorectal surgery. Twenty-four individuals (13 male) undergoing colorectal surgery were included. They were randomly divided into two groups. In addition to conventional chest physiotherapy, group 1 was performed EMT (n=12), group 2 was performed deep breathing exercises with incentive spirometry (IS) in postoperative period. Respiratory muscle strength, functional capacity, levels of movement and independence, and postoperative pulmonary complications (PPC) were evaluated. Length of stay in hospital (LOS) was recorded
