The purpose of this randomized controlled trial is to evaluate the effect of functional inspiratory muscle training (F-IMT) on spatiotemporal gait parameters in patients with chronic stroke. Sixty participants with chronic stroke will be randomly assigned to either a functional inspiratory muscle training group or a conventional inspiratory muscle training group. Both groups will receive the same conventional rehabilitation program for 8 weeks. The primary outcome is spatiotemporal gait parameters measured using the STEADYS gait assessment system. Secondary outcomes include exercise capacity assessed by the Six-Minute Walk Test (6MWT) and health-related quality of life assessed using the EuroQol Five-Dimension (EQ-5D) questionnaire.
