This is a non-invasive electrotherapy method based on the use of high-frequency current. Penetrating the tissues in the form of electromagnetic energy, the current generates endogenous heat within them. The result of this effect produces a gradual and controlled increase in endogenous temperature, directly inside the tissues. This action leads to intense stimulation of the cells and dilation of the blood vessels, initiating a process of natural regeneration in the body. In this way, the release of endogenous analgesics, biostimulating and regenerative substances (primarily cortisol and endorphins) is stimulated, waste products of cellular metabolism are eliminated, and inflammatory processes are reduced.
