Highlights
1. The HiWalk program, delivering 43 hours of walking training over three weeks, proved highly feasible with a 91% adherence rate and a 98% retention rate among chronic stroke survivors.
2. While the overall cohort showed modest gains, a significant subgroup effect was observed: participants not currently enrolled in other rehabilitation saw a fast walking speed increase of 0.24 m/s (95% CI, 0.06-0.43).
