WebWe are very uncertain about whether therapeutic ultrasound, PEMF, Iodex phonophoresis, continuous short wave diathermy, a combination of Iodex iontophoresis with continuous short wave diathermy, or a combination of therapeutic ultrasound with transcutaneous electrical nerve stimulation (TENS) are effective adjuncts to exercise. WebDiathermy is produced by rotation of molecular dipoles in high frequency alternating electric field – the effect produced by a microwave oven. ... Waveforms in electrosurgery. Different waveforms may be generated by the electrosurgery machine for different procedures. Continuous single, high frequency (>400 V) sine wave used at high heat for ...
WebShort-wave diathermy current is a high frequency AC. The heat energy obtained from the wave is used for giving relief to the patient. Its frequency is 27 120 000 Hz, and the wavelength is about 11 m. The types of applications are condenser field method and cable method (Figures 1 and 2). WebFeb 1, 2024 · Surgical Diathermy Machine • Waveform and frequency spectrum used varies from one manufacturer to the other. • Requires a high temperature arc, exceeding 1000°C at the operative site. • The cross-section of the arc is extremely small, less than 1 mm diameter, leading to a high current density in the arc.

The earliest observations on the reactions of high-frequency electromagnetic currents upon the human organism were made by Jacques Arsene d'Arsonval. The field was pioneered in 1907 by German physician Karl Franz Nagelschmidt, who coined the term diathermy from the Greek words dia and θέρμη therma, liter…
