Interferential 520P Plus Interferential 520P plus

The application of low-frequency electric currents at an appropriate depth in the tissue causes dissatisfaction and pain in skin and surface areas of the patient’s body. Therefore, in order to reduce pain and provide comfort for the patient, there is a need to apply currents with higher frequencies. In the case of interferential or cross-patterned techniques, which typically use four electrodes, two currents with a medium frequency (carrier) are applied to the tissue, which interfere with each other at the depth of the tissue; the result of this interference is a low-frequency electrical stimulation (beat frequency). This technique allows the deep tissues to be stimulated with a low frequency by passing the current through the skin easily and blocks pain signals.
