Diathermy is produced by two techniques: short-wave radio frequencies in the range 1–100 MHz (shortwave diathermy) or microwaves typically in the 915 MHz or 2.45 GHz bands (microwave diathermy), the methods differing mainly in their penetration capability. [4] [5] [6] It exerts physical effects and elicits a spectrum of physiological responses.
