Diathermy is a medical treatment that uses electrical currents to produce heat in body tissues. The heat can relieve pain, stimulate circulation, and promote healing. Think of it as a deep-heating treatment for sore muscles. It's often used in physical therapy to treat conditions like arthritis, muscle spasms, and tendonitis. Unlike superficial heating methods, diathermy penetrates deeper into the tissues. There are various types, including shortwave, microwave, and ultrasound diathermy.
