What is diathermy?

Diathermy is defined as a technique for deep heating tissues using electromagnetic energy. This therapeutic method involves the application of high-frequency electrical currents, which generate heat within the body’s tissue, thereby promoting increased blood flow and accelerating healing processes.

The other options do not accurately reflect the definition or purpose of diathermy. Cold therapy, for instance, is focused on reducing inflammation and pain rather than promoting deep tissue heat. The treatment of telangiectasia, which refers to small, dilated blood vessels on the skin, is not specifically addressed by diathermy techniques as it does not focus on deep tissue heating. Lastly, massage therapy typically involves manual manipulation of muscles and tissues rather than electromagnetic energy or heating techniques.
