Microwave diathermy is a therapeutic technique that uses microwave energy to generate heat within body tissues. This method is often employed in physical therapy to relieve pain, reduce inflammation, and promote healing in muscles and joints. The microwaves penetrate the skin and target deeper tissues, providing localized warmth. During a microwave diathermy session, a device emits microwave radiation, which is absorbed by the tissues. This process increases blood flow and enhances metabolic activity, aiding in recovery from injuries or chronic conditions. It is a non-invasive treatment option commonly used in rehabilitation settings.
