ABSTRACT:
A low-frequency electrotherapeutic device can overcome problems ascribable to tolerance in neural response and problems ascribable to accumulation of electric charge in a living body, thereby affording a comfortable massaging effect. Each electrode can be designated as a different electrode or as an indifferent electrode by a controller. Electrodes do not assume a fixed paired structure, and the path of stimulating electric current is changed at predetermined intervals by scanning electrodes serving as different electrodes. The path of an electric current flowing on the skin of a living body can be changed in various ways, the number of which corresponds to the number of paths connecting the electrodes. Consequently, it becomes possible to freely select a desired electric current path or a desired combination of electrodes in accordance with a program stored in a control section (CPU) incorporated in the controller. Also, it becomes possible to automatically change the combination at predetermined intervals. As a result, the apparent electrode position on the base film sheet changes, so that the stimulating position varies.
