This pilot clinical trial aims to evaluate the feasibility and safety of a remote exercise intervention program designed to prevent pediatric post-intensive care syndrome (PICS-p) in children discharged from the pediatric intensive care unit (PICU). Children aged 3 to 18 years who received intensive care for at least 48 hours and have not recovered to their pre-admission functional status will participate in an individualized home-based exercise program for 12 weeks. The intervention includes remotely supervised exercise sessions, prescribed self-exercise, and weekly monitoring using videoconferencing. Study assessments will be performed at baseline, immediately before intervention initiation, monthly during the 12-week intervention, and 1 month after completion of the intervention to evaluate feasibility, safety, functional recovery, and maintenance of treatment effects.
