Abstract
DIATHERMY, or heating of deep tissues, must be accomplished through the absorption of radiant energy in the region to be heated. Conduction methods such as infrared or hot packing fail because of the rapid convection of heat by the flow of blood. Conventionally diathermy has come to be synonymous with high-frequency electromagnetic heating. Recently, however, ultrasonic energy has been introduced to accomplish a somewhat similar clinical purpose.
