  • Patent number: 7418294
    Abstract: In the field of electrotherapy, there are currently known devices and methods, in which either the frequency or the amplitude of a therapeutic current is varied. According to a representation of the amplitude on a logarithmic frequency scale, said methods are designated correspondingly as methods of vertical or horizontal stimulation. Various advantages and disadvantages are associated with both methods. The invention relates to a device for carrying out an electrotherapeutic method, according to which the amplitude (A) and the frequency (f) of the therapeutic current (iB) are simultaneously varied within a therapeutic frequency band (fB), which lies in the medium frequency range, in such a way that the method is carried out in discrete frequency steps, either in the range of different frequencies lying just below a stimulation threshold (RS), or periodically between a stimulation that lies above the threshold and a stimulation that lies below said threshold.
