S1 nerve root damage can cause sensory deficits in the posterior lateral thigh, posterior calf to the lateral aspect of the foot, and pain radiating from behind the buttock along its nerve distribution area to the little toe. Rehabilitation training can be carried out through five-point training, swimming and straight leg raising. 1. Five-point training: the patient lies flat, bending the knees and hips, using the elbows, feet and head for five-point support, lifting the hips upward, holding for 3 to 5 seconds, and then slowly lowering. This method can effectively exercise the strength of the lumbar back muscles and reduce the symptoms of nerve root compression. 2. Swimming: Swimming due to the buoyancy of the water, you can exercise the lumbar muscles at the same time to reduce the pressure on the lumbar spine, help to restore the lumbar spine physiological curvature, lifting the compression of the nerve root. It also helps to enlarge the intervertebral foramina and the vertebral body space, so that the intervertebral foramina can alleviate the role of nerve compression. 3. Straight leg raising: the patient takes the lying position or sitting position, keeps the knee joint straight, and raises the lower limbs with the strength of the thighs. Clinical application for the lower lumbar segment lumbar disc herniation caused by lower limb symptoms, has a certain effect. In addition, it can also be used to lift the nerve root by pulling the nerve root, and the nerve is moved passively in the spinal canal, so that the relative position of the nerve root and the nucleus pulposus can be improved, and the purpose of lifting the compression and adhesion of the nerve root can be achieved. In addition to exercise, massage, traction, and the use of neurotrophic drugs such as methylcobalamin can be used to help recovery. Normally, good posture should be maintained, and work should be combined with labor and rest, not overwork. Reduce weight appropriately. And be sure to protect the lumbar region from trauma or cold stimulation. It is recommended that patients under the guidance of the doctor for rehabilitation therapy, and strictly follow the doctor’s instructions to use drugs.
