Expiratory muscle training versus incentive spirometry after colorectal surgery

Aim: The aim of this study was to compare the effects of expiratory muscle training (EMT) and incentive spirometry (IS) after colorectal surgery. Material and Methods: Twenty-four individuals (13 were males) 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 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. Results: Respiratory muscle strength, increased in both groups after treatment (p<0.05), but there was no difference between the groups (p>0.05). Functional capacity decreased in both groups, and there was no difference between the groups (p>0.05). PPC did not develop, and the LOS of the groups was similar (p>0.05). Mobility and independence levels improved in both groups at discharge (p<0.05), but there was no difference (p>0.05). Discussion: IS and EMT in addition to pulmonary rehabilitation improve respiratory muscle strength, have no side effects, and can be easily used in the clinic as alternatives to each other after colorectal surgery.
