About

In the natural sciences, the term diathermy means "electrically induced heat" and is commonly used for muscle relaxation. It is also a method of heating tissue electromagnetically or ultrasonically for therapeutic purposes in medicine.[1] In surgery, it is used as a method of electrocauterization, for example in controlling bleeding or cutting through tissues.[2]

Therapeutic ultrasound refers to heating of tissues by ultrasound for the purpose of therapeutic deep heating. If precautions are followed no tissue is ordinarily damaged. It is generally used in physical therapy biomedical applications.[3]

Electric diathermy uses high frequency alternating electric or magnetic fields, sometimes with no electrode or device contact to the skin, to induce gentle deep tissue heating by induction or dipole rotation. If precautions are followed no tissue is ordinarily damaged. It is generally used in physical therapy biomedical applications.[4]
