Generally, within 3 months after the injury, it belongs to the healing period, and patients are mainly bed-bound to exercise. Rehabilitation exercises should be started as early as possible, 1-2 days after the injury, in order to increase the muscle strength of the low back and restore the stability of the spine. Low back muscle training can be used “five-point support method”, that is, the patient to take the supine position, with the head, elbows and feet to support the body, the waist up, try to vacate the rear extension; patients can also take the prone position, the upper limbs straight back, head and chest back, abdominal, or the lower limbs straight back extension, good physical condition of patients can also be the upper and lower limbs at the same time back extension, in an arc. It is worth noting that this is the healing period of the bones, avoiding forward flexion of the spine and not premature upright weight-bearing, which may aggravate the deformation of the fractured vertebrae and affect the healing of the fracture. Patients should pay attention to the activities of the joints of the limbs while performing lumbar exercises to prevent disuse atrophy of the limb muscles, joint contracture and bone decalcification. Rhythmic movement of the joints of the lower limbs can promote blood circulation and prevent thrombosis of the lower limbs. Patients should also strengthen respiratory function exercise to maintain normal lung function. Commonly used methods include deep breathing, lip contraction breathing (such as whistling-like), etc. The patient enters the recovery period 3 months after the injury. Patients should continue to strengthen the low back muscle strength exercises to prevent posterior back pain. At the same time do flexibility and flexibility exercises of the spine, patients can ride on a gymnastic bench to bend the spine in all directions to prevent the medullary joint from replacing the lumbar activities. Training to strengthen the back muscles can be done in conjunction with appropriate abdominal muscle training (such as sit-ups).
