Short waved diathermy is the therapeutic elevation of temperature in the tissue by means of an oscillating electric current. Short Wave diathermy current is a high frequency alternating current. The heat energy obtained from the wave is used for giving relief to the patient. Its frequency is 27.12Mhz. and the wavelength is 11 metre. The tissue and body organs are overheated, which increases local metabolism, supports absorption of chronic inflammatory, post-injury and post-operation infiltrates, improves tissue elasticity and has analgetic effects.
