Bridge exercise: Before conducting specific tests, participants should familiarize themselves with the relevant test actions and procedures. The key points of bridge exercise are: the subject is placed in a supine position, with both hands crossed in the center of the abdomen, the knee joint flexed, both feet flat on the bed surface, and the buttocks lifted off the bed surface with force. The patient is instructed to do bridge exercise as much as possible until the knee joint, hip joint, and neck are on the same line, which is considered qualified for bridge exercise;

A common clinical tourniquet (7cm * 50cm in size) is placed in the middle section of the patient's thigh on the affected side, connected to a pressure gauge, observed and gradually pressurized to 160-170mmHg for about 10 minutes, then depressurized for 1 minute, and then re pressurized to 160-170mmHg. Each training session lasts for 20 minutes, once a day, five times a week, for a total of 8 weeks.

The total score of lower limb motor function is 34 points, including 7 major items and 17 minor items. Each minor item has three score levels of 0, 1 and 2. Zero points means that the action cannot be performed, 1 point means that the action can only be partially completed, and 2 points means that the action can be fully completed. The higher the score, the better the lower limb motor function of patients. This scale is widely used in the rehabilitation evaluation of hemiplegic patients and can reflect the lower limb motor function of patients.

The total score of the scale was 56 points, and there were 14 test items. Each item was rated from 0 to 4. A score of 4 indicated that the patient could perform the needed actions well, and a score of 0 indicated that the patient could not perform the actions at all. The higher the score is, the better the balance ability of the patient.

used to evaluate the ability of patients to perform activities of daily living, including the ability to complete daily tasks such as eating, moving, dressing, and walking. The higher the score is, the better the function. The activities related to lower limb function selected in this study included walking, moving, going upstairs, and toileting, with a total of 55 points.

The patient is asked to walk as far as possible along a 30-m minimally trafficked corridor for a period of 6 min, with the primary outcome measure being the 6-min walk distance measured in meters.
