ABSTRACT:
In interference current therapy, medium-frequency alternating currents are applied by means of electrodes to the body of a patient that is to be treated, the currents differing by a low-frequency difference frequency and interfering with each other in the area under treatment with development of a low frequency beat signal that can effect stimulation. Especially in the case of low frequencies, precise control of the frequency interference current is difficult, and at least one of the medium frequencies must be variable, for adjustment of the low frequency. According to the invention, a common oscillator is provided for both medium frequencies, the essentially higher frequency output of which is divided by a programmable divider into two or more frequencies that differ by the required amount, whereby at least one of the dividers is variable. Various schemes are described for execution of variable frequency division.
