What is the effect of electrical stimulation after spinal cord injury?

Two months ago, a 23-year-old patient with spinal cord injury was admitted to functional neurosurgery. We asked the medical history in detail. The patient accidentally fell from the second floor when repairing the house at home three years ago. At that time, the muscle strength of both lower legs completely disappeared, could not move, and the feeling below the waist disappeared. At that time, after the L1 ~ L3 vertebral body stabilization and compression operation in the emergency department of the hospital, we gradually had some strength. At present, I can walk a few steps with a crutch, feel insensitive, and the skin temperature of my lower limbs is colder than that of other normal parts. Bedsore occurs due to decreased skin feeling and poor blood supply of lower limbs. Sexual function is not very good.

The team decided to perform spinal cord electrical stimulation. The spinal cord electrical stimulation system consists of three parts: an electrode implanted into the epidural space of the patient’s spinal cord, an stimulator implanted subcutaneously in the abdomen or buttocks to emit electrical pulses, and an extension wire connecting the two. Try to strengthen and stimulate the spinal nerves with residual function to restore function.

The patient received the method and installed electrical stimulation within 2 weeks. On the second day of installation, lower limb numbness appeared. The functional neurosurgeon team set the patient to the voltage range suitable for him in detail, and taught the patient to use the remote controller to adjust the voltage according to their own feelings to stimulate the spinal cord nerves and lower limb feelings.

After 2 weeks, the patient felt significantly improved and the skin temperature was much better than before. After discussion, the family decided to install batteries and accept spinal cord electrical stimulation surgery.

After the operation, the functional nerve rehabilitation team carefully formulated a rehabilitation plan suitable for the patient. In less than 2 months, the patient’s bedsore gradually decreased, and his lower limbs also had the strength to walk for 1 kilometer, and sometimes he could leave the crutch. Sensory function and sexual function have also been significantly improved. Under the operation and rehabilitation treatment, the patients’ quality of life has been significantly improved and their confidence in life has been reshaped.
