The use of „horizontal” stimulation makes it possible to achieve a stimulatory effect on the synchronic frequency of stimuli of functional potentials in the stimulated cells, as well as electrobiochemical and electrophysical effects, and, with higher dosages, blockage of nerve conductance, which greatly increases the chances of achieving therapeutic success. The WaDiT device produces all the various kinds of effects needed in selective therapy in terms of an alternating electromagnetic field (medium frequency current in the high tone range from ca. 4000 Hz to 12,000 Hz). This range is characterized by high local systemic tolerance. WaDiT devices operate in a wide range of high tones. This results in especially good modulation in tissue, and consequently many additional effects that are medically and biologically advantageous.
