简要总结
This is a cross-sectional study to determine the optimal inspiratory muscle training (IMT) intensity for stroke survivors. Participants will breathe through a pressure threshold inspiratory loading device with varying loads in random order. Each IMT intensity protocol consists of 10 breaths. During the test, accessory inspiratory muscle activity will be measured with surface electromyography (sEMG) and diaphragm thickness will be used to assessed with ultrasonography. Repeated-measures ANOVA will be used for statistical analysis to determine the most effective training intensity for future study.

结局指标
主要结局
Diaphragmatic thickening fraction
时间窗: Data will be measured at baseline and at the end of each inspiratory muscle training intensity protocol;
Diaphragmatic thickening fraction is determined by "(thickness of the diaphragm at end inspiratory - thickness at end expiratory)/thickness at end expiratory". Diaphragmatic thickness will be measured by ultrasonography.
次要结局
- Perceived Exertion Borg scale(Data will be measured at the end of each inspiratory muscle training intensity protocol;)
- Muscle activation of the sternocleidomastoid muscle(Data will be measured at baseline and at the end of each inspiratory muscle training intensity protocol;)
