Patients were divided into two groups: the experimental group (E group) and the control group (C group). The E group received standard care, walking exercise, and elastic band exercise, and wore a smart bracelet to record walking steps and sleep for three months. During the first month, participants performed walking exercise for 100 minutes per week and used a red elastic band for resistance training. In the second month, walking exercise increased to 150 minutes per week with a green elastic band. In the third month, walking exercise increased to 150-300 minutes per week with a blue elastic band. The C group wore the smart bracelet to record walking steps and sleep for three months. Each group included 34 participants. The study was conducted from September 9, 2021, to December 31, 2025. Exclusion criteria included panic disorder, cognitive impairment, current cancer treatment, angina pectoris or myocardial infarction within the past 3 months, participation in high-intensity rehabilitation exercise, and walking dysfunction.
