Which modality uses shortwave or microwave energy to heat tissue?

Shortwave and microwave energy are used to generate heat within deeper tissues, which is the hallmark of diathermy. This modality applies RF energy to tissues so the electromagnetic fields cause molecular motion and friction that produce substantial internal heating, enabling treatment of deeper structures beyond surface heat. Infrared heats mainly from radiant energy at the skin’s surface, so it’s not the same deep heating modality. Ultraviolet involves high-energy light with effects other than heating in typical therapy use, and whirlpool relies on heated water transferring heat through conduction and convection rather than electromagnetic energy. Diathermy is the choice when the goal is heating deeper tissues with shortwave or microwave energy.
