LOW-FREQUENCY THERAPEUTIC APPARATUS

PROBLEM TO BE SOLVED: To provide a low-frequency therapeutic apparatus having a plurality of electrodes capable of being switched freely which intelligibly informs a user where to treat. SOLUTION: The low-frequency therapeutic apparatus comprises a plurality of electrode pairs, a polarity switching circuit for switching the electrodes freely and for applying voltage between the electrodes by switching a voltage polarity arbitrarily, and a display section for displaying conducting state of electric current flowing through the electrodes. The display section has electrode patterns 31p, 32p, 41p and 42p representing the electrodes in a simulated fashion respectively and a conduction pattern section 60 with conducting patterns 61-66 showing the locations of the electrodes through which electric current flows, and turns on the patterns when electric current flows. With such a configuration, the location of the plurality of electrodes through which electric current flows becomes easy to recognize visually and the user can easily feel treatment effect. Effect of recognition by means of such a display is especially enhanced when the electrode pair through which electric current flows is not determined and is switched freely.
