Darsonvalization is a method of physiotherapy based on the use of high-frequency pulsed current (110–400 kHz), high voltage (tens of thousands of volts), and low power (up to several milliamperes).

With local darsonvalization, the current from the device to the patient is supplied by means of glass capacitor vacuum electrodes (Fig. 1), with the general darsonvalization (induction therapy) of the patient in a sitting or lying position placed in a large solenoid (Fig. 2).
The therapeutic effect in case of local darsonvalization is exerted by a pulsed high-frequency current passing through the patient’s entire body and an electrical discharge arising between the patient’s skin and the vacuum electrode; with general darsonvalization, the therapeutic effect of a high-frequency current induced on the patient's body according to the law of electromagnetic induction.
Under the influence of local darsonvalization, blood circulation and tissue trophism are improved, and the tone of tissues, vessels, and skin is normalized. Local darsonvalization is indicated for diseases of the peripheral nerves, blood vessels and muscles with painful phenomena, for trophic tissue disorders, skin and hair diseases for which their nutrition is impaired, and chronic inflammations of the nasal cavities. In addition, local darsonvalization is used in cosmetics.
With general darsonvalization, the functional state of the autonomic nervous system is normalized, the metabolism increases, and the increased blood pressure decreases. General effects are indicated in hypertension in the early stages, some neuroses.
Darsonvalization is contraindicated in malignant tumors, atherosclerosis and hypertension in the late stage.
The Iskra-1 apparatus (Fig. 3) is used for local darsonvalization, and Vortex-1 for general use (Fig. 4). Procedures for local darsonvalization are performed in the supine or sitting position of the patient; sliding circular or translational movements move the vacuum electrode on the skin area to be exposed (Fig. 5), powdered with talcum powder or powder, mucous membranes, for example gums. In the body cavity ( rectum ) injected vacuum electrode, pre-lubricated with petroleum jelly. Electric current is switched on only after the electrode is installed on the body or in the body cavity. After the procedure, the glass part of the electrode is washed with soap and rubbed with alcohol, do not boil. Darsonvalization with a long spark is used for cauterization . The duration of procedures for local darsonvalization is from 3 (for example, during darsonvalization of the eyelids) to 30 minutes. (for example, in the initial forms of obliterating endarteritis ); with a total darsonvalization - 10-15 minutes. They are carried out daily or every other day, an average of 15-20 procedures per course of treatment. The doctor prescribes darsonvalization, the nursing staff conducts the procedure.
