Abstract
In a transcutaneous electric nerve stimulator for producing in a predetermined sequence of different types of waveforms (in which the frequency varies, the signal is successively and/or intermittently created, etc.), when the user depresses a predetermined switch while a desired waveform is being outputted, a low-frequency signal of the waveform is thereafter continuously produced. In a transcutaneous electric nerve stimulator capable of selectively producing low-frequency signals of at least two different kinds, a kind of output signals at a termination of a treatment is stored in a memory such that a low-frequency signal of the stored kind is produced when the stimulator is started for a subsequent treatment.
