[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 FEF25-75 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 FEF25-75. 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.
[目的] 本研究的目的是验证一种新方法，即通过同时应用腹部刺激和吸气肌训练（IMT）来训练吸气肌和呼气肌，以改善呼吸功能，提高慢性中风患者IMT的效率。[对象] 18例中风患者被随机分为实验组（n = 9）和对照组（n = 9）。[方法] 实验组接受伴有腹部刺激的IMT，对照组仅接受IMT。在干预期内，实验组和对照组每天接受20分钟训练，每周3次，共4周。为检查受试者的肺功能，使用电子肺活量计测量FVC、FEV1、PEF和FEF25-75。用7.5MHz线性探头超声成像系统测量的数据计算膈肌厚度比。[结果] 实验组和对照组患侧膈肌厚度比均显著增加，而非患侧未增加。关于肺功能，实验组的FEV1、PEF和FEF25-75显著增加。比较两组干预前后的变化，结果显示FEV1和PEF存在显著差异。[结论] 本研究发现，伴有腹部刺激的IMT可改善慢性中风患者的肺功能。
