Abstract

[Purpose] The aim of this study was to investigate the effect of combined respiratory muscle training on expiratory muscle activity in stroke patients. [Subjects and Methods] Twenty-five stroke patients were assigned to either the intervention group (n=12) or the control group (n=13). Both groups participated in a conventional stroke rehabilitation program, while the intervention group also received respiratory muscle training for 20 to 30 minutes a day, 3 times a week, for 8 weeks. Surface electromyographic data were collected from the rectus abdominis, internal oblique, and external oblique on the paretic side. Pulmonary function (forced vital capacity) and cough capacity (peak expiratory flow) also were measured. [Results] Both groups showed a significant increase in muscle activity after the intervention. However, the intervention group also showed significant increases in forced vital capacity and peak expiratory flow. Comparison of the 2 groups revealed that the intervention group had greater improvements in pulmonary function, cough capacity, and muscle activity. [Conclusion] The results of this study suggest that combined respiratory muscle training has positive effects on both respiratory function and expiratory muscle activity in stroke patients.
