The aim of this study is to observe the therapeutic effect of Baduanjin on improving shoulder joints in MHD patients. A total of 60 maintenance hemodialysis patients will be included and randomized into an intervention group of 30 cases and a control group of 30 cases. The intervention group underwent a 30 minute Baduanjin exercise under the guidance of a professional doctor before the dialysis day, including a 5-minute warm-up exercise, a 20 minute Baduanjin exercise, and a 5-minute relaxation exercise. The intervention group practice Baduanjin three days a week, while the control group maintain routine treatment and daily activities. Measure the indicators of each group at baseline, months 6, 12, and 18. The evaluation of shoulder joint function is based on the shoulder Constant score (which includes three dimensions: pain, daily living activities, and active range of motion); The quality of life score is based on the SF-12 score, and the emotional score is based on the Anxiety and Depression Scale.
