[ad. G. diathermie (F. Nagelschmidt 1909, in Münch. med. Wochenschr. 14 Dec. 2575/1), f. Gr. διά through + θερµός heat + -y3.]
The therapeutic passing of high-frequency electric currents through the body by means of external electrodes in order to generate heat within the body; medical diathermy, diathermy in which the tissues are warmed but not sufficiently to change their nature; surgical diathermy, diathermy in which there is sufficient heating to produce a local change such as destruction of tissue or coagulation of bleeding vessels.
1910F. Nagelschmidt in Proc. R. Soc. Med. (Electro-Theropeutic Sect.) IV. 1 Diathermy is one effect of high-frequency currents of all kinds. 1910Archives Roentgen Ray June 19 Diathermy is but one phase of d'Arsonvalisation, which, besides the production of heat, has other physiological effects dependent on the tension, length, form and frequency of the waves. 1911Brit.

Diathermy v. 55 Short-wave diathermy with its higher frequency as compared to long-wave diathermy is more convenient to apply to a patient since it can be used with air-spaced electrodes. 1966Listener 13 Jan. 62/3 When a third subject was heated by diathermy—which is a kind of heat treatment sometimes given in hospitals—his speed of counting was increased too. |
