Functional exercise is very important for patients after lumbar spine surgery. Functional exercise of the limbs during postoperative bed rest can prevent muscle atrophy, prevent nerve root adhesions, improve the body’s resistance and prevent complications. Postoperative chest expansion and deep breathing exercises can increase lung capacity, promote pulmonary ventilation and prevent pulmonary complications; postoperative daily clockwise abdominal massage can enhance gastrointestinal peristalsis and reduce abdominal distension, constipation and urinary retention. (1) To promote blood circulation of the limbs and prevent deep vein thrombosis of the lower limbs. (2) To restore the muscle strength of the atrophied muscles and restore the function of the limbs. (3) To prevent postoperative nerve root adhesions. 2, exercise methods: (1) 1-2 days after surgery, you can do the exercise of the extensor and flexor muscles of both lower limbs Extensor exercise: supine position, straighten the knee joint, foot force dorsiflexion, adhere to 5-10 seconds and then relax, alternate between the two legs as a group. At the beginning, do 10-20 sets each time, 2-3 times a day, gradually increasing the number of exercises. Flexor training: supine position, straighten the knee joint, do plantarflexion training, 2-3 times a day, 10-20 times per group at the beginning, then gradually increase the number of exercises. (2) On the 3rd-14th postoperative days, you can do functional exercises of the integrated lower limb muscles. Method: supine position, do activities of knee extension and hip flexion, alternating between the two legs repeatedly, 2-3 times a day, 10-20 times each time at the beginning, and gradually increase later. Second, after 2 weeks postoperative lumbar back muscle and abdominal muscle exercise 1, purpose: postoperative lumbar back muscle and abdominal muscle exercise can make its muscle strength, play the role of internal support, is conducive to the stability of the lumbar spine, consolidate the effect of surgical treatment. 2, exercise methods: (1) “five-point support” method: supine position, head, elbows and heels for the fulcrum, waist and back as much as possible suspended. (2) “four-point support” method: supine position, hands and double heel as a fulcrum, chest and waist up, torso suspension, mainly for young adults. (3) “three-point support” method: supine position, upper limbs placed in front of the chest, head and double heel as a pivot point, waist and back as far back as possible, so that the back suspension. Cervical spine lesions are used with caution. (4) “little swallow fly”: prone position, abdominal support, double upper limbs, double lower limbs and head as far back as possible. 3, exercise principles: 5-10 seconds each time, and then put down the rest 5-10 seconds, and then repeat the above actions, so repeatedly 5-10 for a time. 2-3 times a day, step by step, gradually increase the number and frequency of training to the lumbar muscles without soreness is moderate. 1. The functional training program after lumbar spine surgery should be tailored to the individual, and the intensity of the rehabilitation training should be decided according to the age, condition, mode of surgery and the patient’s physical condition and tolerance. 2, any functional training should follow the principle of “step by step”, with the number from small to large, the time from short to long, the number of times gradually increasing, and the intensity from weak to strong. 3, rehabilitation training should be carried out under the guidance of doctors and nurses. 4.Patients whose age of surgery is over 65 years old, those with cardiac insufficiency, those with large intraoperative bleeding, and those with multiple laminectomies, the time and manner of exercise should be appropriately delayed to start exercise or moderately reduce the intensity of exercise according to medical advice. 5.After the completion of functional training, it should be moderate to have no obvious soreness in both lower limbs and lumbar muscles. 6, postoperative activities on the ground: (1) first shake up the bed, a soft pillow in the lumbar area to sit for about 20 minutes to adapt to the change of position. (2) If there is no panic, nausea and other uncomfortable symptoms, you can sit on the edge of the bed with your buttocks as the center. (3) If there is no discomfort, you can stand for a moment with the help of nursing staff or family members, or you can lift your legs in place with the power of the exercise frame. (4) If there is no panic or leg weakness, you can walk with the help of the walking frame. (5) The lower limbs and waist muscles have strength before they can gradually walk independently. Fourth, down that wear lumbar support 1, the purpose: (1) to maintain the normal physiological convexity of the lumbar spine, increase the stability of the spine. (2) to reduce the load on the spine. (3) To prevent excessive twisting and turning of the lumbar region and to speed up the healing of the bones. V. Post-discharge precautions 1. Diet: Eat a high protein, high vitamin, low fat, easy to digest diet, such as eggs, lean meat, fresh fruits and vegetables. Avoid overeating and pay attention to the diet. If you have special diseases, such as diabetes, you should control your diet. If you have chronic diseases, such as heart disease, diabetes or have discharge with medication, take it on time; and keep the bowel movement smooth. 2, rest and exercise: bed rest is the main, lying on a hard bed is appropriate, to ensure adequate sleep time; continue functional training, such as quadriceps, lumbar back muscles and abdominal muscle training, to gradually increase, to quantify; avoid bending arch back action; avoid lumbar scoliosis, twisting sudden force; avoid heavy physical labor and intense exercise; avoid wearing high heels; try to sit less, more bed, appropriate activities. Insist on wearing a lumbar brace or support for 3 months.
