Abstract

An electronic stimulation device for electrically stimulating at least one dorsal root ganglion with relative low pain sensations without generating relative much sensations of paresthesia comprises at least one electronic stimulation unit. The electronic stimulation unit includes at least one first electrode and at least one second electrode, and it delivers a high-frequency 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 dorsal root ganglion, and the electric field strength ranges from 100 V/m to 1000 V/m.
