Diathermy refers to a therapeutic technique used in medicine and physical therapy that involves the application of high-frequency electromagnetic currents to various parts of the body. It is administered through specialized devices called diathermy machines, which generate and deliver these electric currents.
The primary purpose of diathermy is to provide therapeutic heat to the tissues being treated. The high-frequency currents produced by the diathermy machine generate heat within the tissues, primarily targeting deep muscles and joints. This deep heat therapy can promote blood circulation, alleviate pain, reduce inflammation, and enhance the healing process.
There are different types of diathermy, including capacitive and inductive diathermy. Capacitive diathermy uses electrodes that are placed on the surface of the body, while inductive diathermy employs coils or pads placed near the body. In both cases, the electric currents cause molecules in the tissues to vibrate and generate heat.
Diathermy is commonly used to treat various conditions, such as muscle and joint pain, arthritis, muscle spasms, bursitis, and even certain types of tumors. It is often utilized in physical therapy settings to aid in rehabilitation after injuries or surgeries. However, diathermy is not suitable for everyone and should be avoided in certain circumstances, such as during pregnancy or when a patient has metal implants.
In summary, diathermy is a non-invasive therapeutic technique that utilizes high-frequency electromagnetic currents to generate heat within the body's tissues. It is employed to promote healing, relieve pain, and improve circulation, often utilized in physical therapy and medical settings.
