About this trial
This study is designed to explore the effects of a 4-week protocol of inspiratory muscle training (IMT) at 50% maximum inspiratory pressure (MIP) on respiratory function, diaphragm thickness, balance control, exercise capacity, and quality of life in people after stroke. To ascertain the effect of IMT on the relationship between diaphragm muscle contraction and activation of other trunk muscles, this study also explores whether any effect of the 4-week IMT protocol on balance control is associated with changes in the anticipatory posture adjustments (APAs) time - the onset time of postural muscles during a required task (e.g., the rapid shoulder flexion test).
