Electromagnetic Radiation: Diathermy and Laser

A set of vocabulary flashcards derived from lecture notes on electromagnetic radiation, diathermy, and laser therapy in physical therapy.

Electromagnetic Radiation

A form of energy that travels through space and is characterized by its wavelengths, encompassing a spectrum from radio waves to gamma rays.

Diathermy

A therapeutic treatment involving the use of electromagnetic energy to generate heat within body tissues for pain relief and healing.

Non-ionizing Radiation

Radiation that does not carry enough energy to ionize atoms or molecules or remove tightly bound electrons.

Ionizing Radiation

Radiation with enough energy to remove tightly bound electrons from atoms, potentially leading to chemical changes in the tissue.

Continuous Short Wave Diathermy (CSWD)

A type of diathermy that delivers higher doses of electromagnetic energy continuously.

Pulsed Short Wave Diathermy (PSWD)

A type of diathermy that delivers lower doses of electromagnetic energy intermittently.

Photobiomodulation

A process by which light photons are absorbed by cells, leading to various beneficial biological responses.

Visible Light

The part of the electromagnetic spectrum that can be seen by the human eye, typically in wavelengths between 400 and 700 nanometers.

Laser

Light Amplification by Stimulated Emission of Radiation; a device that produces a concentrated beam of monochromatic, collimated light.

Class 4 Laser

A powerful laser category that can cause severe skin and eye damage, typically having a power output greater than 500 mW.
