Longwave Diathermy: A Safe and Effective Therapeutic Modality

Longwave Diathermy is a therapeutic device that utilizes electromagnetic waves within the radiofrequency range to achieve deep tissue heating. Operating at a frequency below 1 MHz and with power levels under 75 watts, it offers a gentle yet effective alternative for treatment. Compared to Shortwave Diathermy (SWD), Longwave Diathermy emits lower levels of radiation, making it a safer option for clinical use.

Also referred to as the Capacitive Electric Transfer (CET) technique, Longwave Diathermy has demonstrated several advantages. Numerous studies suggest that it may be more effective than both SWD and ultrasound in certain therapeutic applications.

This modality delivers deep heating through capacitive electric transfer, which helps enhance blood circulation, relax muscles, relieve pain, and promote tissue healing. Its lower frequency and power contribute to its safety, making it a valuable non-invasive option for managing pain and supporting rehabilitation in a variety of conditions.
