Before starting dialysis, Patients perform Baduanjin exercises. All Baduanjin training is provided by a professional doctor who has received training on BaduanJin and obtained certificate. Each session is approximately 30 minutes in duration, consisting of 5 minutes of warm-up exercises, 20 minutes of Baduanjin practice, and 5 minutes of cool-down exercises.

Patients in this group maintain their conventional therapy and daily life activities, and there is no intervention given.

Baduanjin has 8 movement forms, which are easy to learn without special equipment.These advantages make Baduanjin a suitable exercise for dialysis patients.The movements involved in Baduanjin require the individual to reach beyond the base of support, change the base of support between bilateral and unilateral stance, and perform movements in a sustained squatting posture. These maneuvers challenge balance and require muscle strength to be executed successfully.During the exercise of Baduanjin, the knees are half bent and the body center of gravity is stable between the feet, which can effectively develop the strength and endurance of skeletal muscle groups, improving the physical fitness and Bone mineral density.

Grip strength can reflect the strength of hand muscles. The grip strength of both hands of patients was measured using a domestic gripper.The patient took an upright position and grasped the handle with the maximum force. When the display on the machine stopped changing, the value was recorded. The test was repeated three times, and the maximum value was taken to record the results.

The five-times sit-to-stand test is used to evaluate the functional strength of the lower limbs. MHD patients sat on a 46cm chair without armrests, with their feet on the ground and their backs not resting on the chair. Their hands were crossed on their shoulders. They stood up from the chair as quickly as possible without arm support. They completed five sitting and standing movements, and the completion time was recorded.During the test, the patient kept his hands crossed and his knees completely straightened.Three tests were completed, with a one-minute rest between tests. The average value of the three tests was statistically analyzed.

The timed "up and go" test is often used to evaluate functional mobility such as balance and walking required in daily life.MHD patients were seated in a back chair with armrests (the seat was about 46cm high, and the armrest was about 21cm high). A guide line was placed on the ground 3m away from the chair. After the test began, the patient left the chair, stood firmly and walked forward for 3m as fast as possible, crossed the guide line, turned around, and returned to the chair to sit down. The walking aids were not allowed during the test.The test was conducted 3 times in total, with a 1-minute rest between adjacent tests. The average value of the 3 tests was taken for statistical analysis.

The sitting forward flexion test is often used to evaluate the flexibility of the lower limbs of patients.The patient straightened the knee joint, sat on the flat ground with both feet flat on the test board, bent forward, straightened both arms forward, and gradually pushed the cursor with both middle fingertips to the farthest possible distance.The measuring device was 0 point along the plane of the foot pedal board, negative inward, positive forward, in centimeters. The knee joint could not be bent during the test, and sudden force could not be applied.The test was conducted 3 times in total, and the best result was taken for statistical analysis.

Changes from the Short Form-36 (SF-36) and European Quality of Life Five Dimension（EQ-5D-5L）scale at 0 months, 6 months, 12 months. The SF-36 score is used to evaluate an individual's health status and quality of life. The SF-36 score expressed as a number between 0 and 100, with higher numbers indicating better health.
