At present, diathermy is often employed to produce the pelvic heating, since it is thought to give better penetration of heat than hydrotherapy techniques.After World War II, and the release of previously secret information on radar, microwaves (radar, ultra-high-frequency electromagnetic waves of extremely short length) began to be used instead of conventional diathermy for the treatment of many conditions.2 Among the reported advantages of microwave therapy over conventional diathermy are (1) a better ratio of cutaneous to deeper tissue temperatures, (2) better control of the area of application, and (3) absence of the
