The goal of this clinical trial is to evaluate whether a Just-in-Time Adaptive Intervention (JITAI)-based digital exercise rehabilitation program can improve postoperative recovery in children after congenital heart disease (CHD) surgery. The study will examine whether this system can:
Improve cardiopulmonary endurance, cardiac function, and muscle strength Increase rehabilitation adherence and enhance training experience while reducing exercise-related fear Researchers will compare children receiving the adaptive digital exercise rehabilitation program with those receiving standard postoperative rehabilitation to determine whether the digital program provides additional clinical and behavioral benefits.
Participants will:
Wear non-invasive monitoring devices to collect real-time physiological data Engage in daily structured exercise rehabilitation sessions guided by the digital system Receive adaptive adjustments in exercise intensity based on real-time physiological feedback Complete questionnaires on recovery, emotional status, and rehabilitation experience
Children aged 6 to 12 years
Diagnosed with congenital heart disease (CHD) and have undergone cardiac surgery
Clinically stable after transfer to the general ward, with stable circulatory, respiratory, musculoskeletal, and neurological status, and assessed by the clinician as suitable to begin active exercise rehabilitation
Able to understand and cooperate with basic exercise training requirements
Absolute contraindications to exercise rehabilitation, including uncontrolled arrhythmia, acute heart failure, hemodynamic instability, severe aortic stenosis, acute myocarditis, or acute pericarditis
Severe comorbid conditions that could interfere with rehabilitation, including severe hepatic or renal dysfunction, malignancy, or acute infection
Musculoskeletal or neuromuscular disorders that would prevent participation in or completion of the rehabilitation training
