Effects of breathing exercises on recovery after stroke

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study investigates the impact of a 4-week inspiratory muscle training (IMT) program on various rehabilitation outcomes for stroke patients. Participants will engage in IMT at 50% of their maximum inspiratory pressure, with assessments focusing on respiratory function, diaphragm thickness, balance control, exercise capacity, and overall quality of life. The study also aims to understand how IMT influences the timing of muscle activation during postural tasks. Participants will be divided into groups receiving either sham IMT, stable surface IMT, unstable surface IMT, or conventional treatment.
