Diathermia
Diathermia
Diathermia (/daɪəˈθɜːrmɪə/; from the Greek dia, through, and therme, heat) is a therapeutic treatment prescribed by physicians for its healing properties in cases of muscle and joint conditions. It involves the use of high-frequency electric current to stimulate heat generation within body tissues.
Etymology
The term diathermia is derived from the Greek words dia, meaning through, and therme, meaning heat. It was first used in the early 20th century to describe a method of therapeutic heating.
Types of Diathermia
There are three main types of diathermia: shortwave, microwave, and ultrasound. Each type uses different frequencies of electrical current to generate heat.
Shortwave Diathermia
Shortwave diathermia uses high-frequency electric current in the range of 3 to 30 MHz. It is often used in physical therapy and rehabilitation.
Microwave Diathermia
Microwave diathermia uses microwaves, which are a form of electromagnetic radiation, to generate heat. It is often used in the treatment of deep tissue injuries.
Ultrasound Diathermia
Ultrasound diathermia uses sound waves to generate heat. It is often used in the treatment of musculoskeletal conditions, such as arthritis and tendonitis.
Uses
Diathermia is used in physical therapy and rehabilitation to relieve pain, improve circulation, and promote healing in deep tissue injuries. It is also used in surgical procedures to cauterize blood vessels and reduce bleeding.
