Abstract
There are many complications after open heart surgery including impaired functional capacity. Physical therapy, using respiratory muscle training, is the one treatment for improving functional capacity and quality of life. Objective: to investigate the effect of inspiratory muscle training (IMT) on functional capacity in patient undergoing open heart surgery. Methods: Fourteen subjects who underwent open heart surgery were included and randomly assigned into two groups: six patients in the IMT group and 8 in the control group (CO). All subjects received conventional physical therapy. In addition, subjects in the intervention group received IMT. Six-minute walk test was examine before operation and eight postoperative day Results: Both groups, six-minute walk distance were significantly lower after operation (CO; pre-operation 305.33±21.75 meters, post-operation 185.62±20.79 meters, p<0.05) (IMT; pre-operation 315.38±14.79 meters, post-operation 261.06±16.05 meters, p<0.05). Moreover, there were significant differences between six minute walk distance of CO and IMT after operation (CO 185.62±20.79 meters, IMT 261.06±16.05 meters, p<0.05). Conclusion: Functional capacity was decreased after open heart surgery. However, physical therapy combine with IMT can improve functional capacity. Therefore, IMT may be an additional treatment in patient undergoing open heart surgery.
