Shortwave Diathermy: Actualization

Abstract

Short wave diathermy (SWD) is a therapeutic modality that offers the body an increase in temperature, through the high frequency in electromagnetic irradiation, so as not to generate ionization to the tissues. This therapeutic modality works based on the principle that energy is transferred within the layers of deep tissues by a high frequency current and the generation of tissue heat. Therefore, there is an agitation of the molecules in response to an electric field, converting the kinetic energy into heat [1-4]. It uses radio frequency bands generally centered at 13.56MHz, 27.12MHz and 40.68MHz, with the most commonly used frequency being 27.12MHz with a corresponding wavelength of 11.6m (1.5).
