Abstract
A relatively high-frequency electric current is generated, to be applied to the human body by means of one active and one passive electrode. It is distinct because, in order to raise the temperature of the human body in a local sense to 45.degree.-46.degree. C., it comprises a return electrode consisting of a metal plate and an active electrode, likewise metal, of smaller dimensions than the return electrode. The difference in dimensions between the two electrodes, placed facing on either side of the body region to be treated, brings about an increase in the impedances which, combined with the power frequency amplifier generator, brings about the required rise in temperature for treatment at local level.
