Abstract
A closed-loop spinal cord electrical stimulation system includes a spinal epidural electrical stimulation electrode, a low limb electrical stimulation electrode, a closed-loop electrical stimulator and a controller. The spinal epidural electrical stimulation electrode, the low limb electrical stimulation electrode and the controller are electrically connected to the closed-loop electrical stimulator respectively. The spinal epidural electrical stimulation electrode is used for applying a first electrical stimulation to the spinal epidural site, and the low limb electrical stimulation electrode is used for applying a second electrical stimulation to a low limb. The voltage of the first electric stimulation is 400-600 mV, the voltage of the second electric stimulation is 1 V-1.5 V, and the stimulation frequency of the both is 10-20 Hz. The stimulation system can send electrophysiological signals similar to sensorimotor neural circuitry to the subject with spinal cord injury, and can activate and remodel the neural circuit.
