Abstract: In an apparatus for electrotherapy, comprising a circuit arrangement with a terminal for generation of a sequence of voltage pulses and two electrodes for application of these voltage pulses to a part of the body that is to be treated; one of the two electrodes having a surface of comparatively high transition resistance and the other electrode having comparatively low transition resistance towards human skin; the electrode with the surface of high transition resistance being movable over the treated part of the body and the surface being a plastic film; with sequences of pulses of voltages from 1 to 600 V being generated and a current in a microampere range being produced in the tissue; it is provided that the rapid discharge circuit comprises several thyristors which are triggered by optocouplers.
