Postoperative functional exercise is an important measure for the consolidation of the efficacy of lumbar disc herniation surgery, and the absence of effective early postoperative rehabilitation training will affect the degree of functional recovery of postoperative patients. Postoperative rehabilitation functional exercise is mainly based on the patient’s active activities, supplemented by passive activities, and progresses gradually, with the amount of activities from small to large, the amplitude of activities from small to large, and the duration of activities from short to long. The exercise should not make the patient feel fatigue, not to make the back pain or slightly reflect but can tolerate is appropriate. Patients can be assisted to do straight leg raising, starting from 30 degrees and increasing the amplitude day by day. On the third day after surgery, patients should be encouraged to take the initiative to do straight leg raising and double lower limb pedaling exercise, and be assisted to do passive activities such as knee and hip flexion. On the tenth postoperative day, the strength of the lumbar muscles can be strengthened to restore the toughness of the muscles, maintain the physiological anterior convexity of the lumbar spine, increase the stability of the lumbar spine and avoid future recurrence. The rehabilitation exercise method is the five-point support method: the patient takes the supine position, with the head and pillow on the bed, the elbows bent at the tips of the elbows on the bed, the knees bent so that the feet are flat on the bed, and with the five-point support of the head and pillow, the elbows and the feet, the back extensor muscles are contracted with force and the chest is raised forward, so that the trunk leaves the bed completely. At the beginning, do 5-10 times each time, 2-3 times a day, increasing day by day to 20-30 times each time, 5 times a day. After 1 to 2 weeks of practice of the five-point support method, it is changed to the three-point support method (three-point support of the head and feet) and the flying swallow method (prone position with limbs and head raised as high as possible like a swallow flying). Generally, 4 weeks after surgery, patients can get up and move around, bring lumbar girth to protect the waist and walk slowly, but should not do bending and weight-bearing activities and heavy physical labor for 3 months. Continue to insist on lumbar back muscle exercise for at least half a year. When standing and walking, keep the spine upright and hold the chest forward. Pick up items on the ground with a straight back, bend the knees and hips so as to pick up the items in a squatting position.
