Rehabilitation training for spinal dural sac compression mainly focuses on corrective functional training for the affected area, which is generally common in patients with lumbar disc herniation, and can be chosen to improve the strength of the muscles of the lumbar back and to restore the lumbar curvature. 1.Restoring lumbar curvature training (1) Cat stretch: the patient sits in a sitting position with a straight back, letting the lumbar spine slowly shrink back, then stretching the lumbar spine in the opposite direction, while the chest slowly goes up, matching the breathing rhythm. (2) Four-point rotation training: the patient’s knees and hands vertically supported on a flat surface, one side of the hand raised and then the body rotated in the direction of the ceiling, the support side of the stationary, and then slowly back down. With the rhythm of breathing, alternating between the two sides. 2. Low back muscle training (1) Supine breathing training: patients lie on their backs with their legs flexed, and abdominal breathing is performed while the waist is pressed against the bed. (2) Four-point contralateral support training: the patient’s knees and hands vertically braced on the plane, forward and backward lifting the opposite side of the upper and lower limbs, the waist to maintain neutrality. Alternate between the two sides. (3) Swallow fly: the patient takes a prone position, arms naturally placed at the side of the body, arms straightened and then stretched backward, at the same time the head is tilted backward, the neck as far as possible to leave the floor, the lower limbs are straightened and together to the back and upward as far as possible to elevate. Finally, the whole body is relaxed and the trunk is pressed back to the floor. In addition, after spinal cord dural sac compression occurs, it can be treated by lumbar traction, medication analgesia, etc., which is also beneficial to recovery. It is recommended that patients perform the above exercises under the guidance of a professional doctor to avoid secondary injury and aggravation of the condition.
