Abstract
Aims: This study aimed to compare the effectiveness of Incentive Spirometry (IS)   and Inspiratory Muscle Training (IMT) on diaphragmatic excursion in patients undergone coronary artery bypass graft (CABG) surgery.
Methods: Fifty-two patients scheduled for elective CABG were randomized into two groups. Group A received conventional physiotherapy with IS, while Group B underwent physiotherapy with IMT. Diaphragmatic excursion was assessed pre- and post-intervention using ultrasound imaging.
Results: Both groups showed significant improvement in diaphragmatic excursion (IS: 3.6 ± 0.5 cm to 4.8 ± 0.9 cm, IMT: 3.7 ± 0.7 cm to 5.05 ± 0.7 cm; p < 0.001 within groups). No statistically significant difference was found between the groups post-treatment (p = 0.31).
Conclusion: Both IS and IMT significantly improve diaphragmatic excursion following CABG surgery. Either modality can be effectively implemented based on clinical and logistical considerations.
