A microwave diathermy is a therapeutical method that applies electromagnetic energy in microwave frequency bands and is intended to generate deep heat within body tissues. The application of moderate heat by microwave diathermy increases blood flow, speeds up metabolism and the rate of ion diffusion across cellular membranes.
Microwave diathermy uses microwaves to generate heat in the body. It can be used to evenly heat deeper tissues without overheating the skin.
Microwave diathermy provides pain relief in the form of increased metabolic rate, increased blood flow, decreased tissue and blood viscosity, increased extensibility of collagen, and effects on nerves.
