Abstract
A device for low-frequency electrotherapy wherein the output current of a low-frequency oscillator is applied to the subject's body through a pair of electrodes placed on the subject's body, comprising a first oscillator circuit that generates a low-frequency square wave voltage when the load is in connection with the electrode pair; and a second oscillator circuit that generates a therapeutic voltage when the output voltage of the first oscillator circuit is not zero.
