Exercise therapy for lumbar disc herniation: 1, spinal flexibility training: the patient sits, keeping the pelvis immobile, relaxing the lumbar back muscles for lumbar flexion, extension, left and right lateral bending and left and right rotational movements. The speed of movement is smooth and slow, and the amplitude gradually increases. Avoid causing pain; 2, lumbar back muscle and abdominal muscle strength training: after the initial subsidence of pain symptoms, it is appropriate to start lying lumbar back muscle and abdominal muscle strength training as soon as possible, it is appropriate to make the lumbar back muscle and abdominal muscle isometric contraction training, or power training to restore the physiological curvature as the termination point, avoiding lumbar overflexion or overextension of the action. In principle, the lumbar back and abdominal muscles should be trained at the same time in order to balance the front and rear muscles of the spine and to enhance muscle strength at the same time, but the specific should be biased according to the lumbar spine curvature, the size of the sacral anterior tilt angle and the size of the ratio of lumbar back and abdominal muscles. Exercise training should be carried out every day for at least 3 months, and then consolidation training should be carried out appropriately. The training to restore spinal mobility should be started after the nerve root symptoms disappear. Specific training methods are as follows: chest up: supine position, support the bed with both elbows, lift the chest and shoulders; “arch bridge”: supine position, legs flexed, lift the hips while lifting the chest and waist, as if “arch bridge”; upper back extensor training: prone position, first lift the head. The upper body and head lift, hold 5-10 seconds; swallow fly: prone position, under the abdomen pillow, so that the body is “swallow fly ” shape, both hands and upper arms back, trunk and lower extremities are at the same time force back, two knees straight, so that the head and lower extremities form a horizontal line, hold 5-10 s. Each of the above actions Repeat 10 times, the number of repetitions should be small at the beginning, and then gradually increase as appropriate. At least 1 to 2 times a day. Abdominal muscle training: head lift: supine position, both upper limbs flat, upper body and head lift, so that the back from the bed; lower limb lift: supine position, lower limbs together, lift both lower limbs off the bed. Maintain the above posture for 4-10s and repeat 4-10 times.
