Abstract: Provided is a urination disorder treatment device which easily confirms with high accuracy whether it is appropriately used or not. In the urination disorder treatment device, a control portion compares a stimulation pulse 58 by a pair of body-surface electrode pads with a detection pulse 60 of a toe to judge whether a nerve passing through the sacral bone or the vicinity of the sacral bone is appropriately stimulated by the stimulation pulse 58 or not. Further, the detection pulse 60 is generated by reactions of the tibial nerve and/or the peroneal nerve extended up to the tiptoe which are connected to the nerve passing through the sacral bone or the vicinity of the sacral bone by way of the ischiadic nerve.

Abstract: Provided is an electric stimulation treatment device which is capable of outputting a stimulation voltage more efficiently than a conventional device. A urination disorder treatment device includes a pair of body-surface electrode pads 37, an indifferent electrode pad 39 which is larger in area than a body-surface electrode pad 37 with a relatively larger area, of the pair of body-surface electrode pads 37, and disposed in the vicinity of the pair of body-surface electrode pads 37, and a control portion 48 which supplies an electric signal to the pair of body-surface electrode pads 37 and the indifferent electrode pad 39.
