PURPOSE: The purpose of the present study was to verify a new method for improving respiratory functions by applying both abdominal stimulation and inspiratory muscle training (IMT) to train the inspiratory muscle and the expiratory muscle simultaneously, to improve the efficiency of IMT of chronic stroke patients. SUBJECTS: Eighteen stroke patients were randomly assigned to an experimental group (n = 9) and a control group (n = 9). METHODS: The experimental group was administered IMT with abdominal stimulation, and the control group was administered only IMT. During the intervention period, the experimental group and control group received training 20 min/day, 3 times/wk, for 4 weeks. To examine the lung functions of the subjects, FVC, FEV1, PEF, and FEF[25-75] were measured using an electronic spirometer. The diaphragm thickness ratio was calculated from measurements made with a 7.5-MHz linear probe ultrasonic imaging system. RESULT: The experimental group and the control group showed significant increases in diaphragm thickness ratio on the paretic side, but not on the non-paretic side. With regard to lung function, the experimental group showed significant increases in FEV1, PEF, and FEF[25-75]. The changes between before and after the intervention in the two groups were compared with each other and the results showed significant differences in FEV1 and PEF. CONCLUSION: The present study identified that IMT accompanied by abdominal stimulation improved the pulmonary function of chronic stroke patients.
