Abstract

An electronic stimulation device is adapted for electrically stimulating a target zone of an organism. The electronic stimulation device comprises at least one electronic stimulation unit. The electronic stimulation unit includes at least one first electrode and at least one second electrode. The electronic stimulation unit receives an electrical stimulation signal to impel the first electrode and the second electrode to generate an electric field. The range of the electric field covers the target zone, and the electric field strength ranges from 100 V/m to 1000 V/m. The target zone is selected from the group consisting of a dorsal root and a dorsal root entry zone of a spinal cord, and the electronic stimulation unit is configured to be disposed in an anatomical space of the organism, and said anatomical space is selected from the group consisting of a spinal canal, a lateral recess and an epidural space.
