Local darsonvalization is a method of local action by alternating electric current of the corresponding parameters, carried out by a single-electrode method! Through a glass vacuum electrode located above a certain exposed area of the body at a distance of 1-3 mm, or contacted superimposed on a specific area of the skin or mucous membranes of the patient.
Local darsonvalization uses current up to 0.02 mA; voltage up to 25 kV; frequency of current oscillations 50-110 kHz, modulated by pulses of bell-like shape; pulse repetition frequency 50 Hz pulse duration 50-100 μs.
Features of the factor are caused by the appearance of an electric discharge between the vacuum electrode and the skin or mucous surfaces of the patient, which has a superficial, irritating and even cauterizing effect, and also initiates pronounced electrodynamic changes in the surface tissues (displacement currents) followed by conformational rearrangements of the corresponding structures. In addition, as a result of an electric discharge between the electrode and the skin, ozone and nitrogen oxides can form, which in turn affect the receptors of the skin and mucous membranes on the basis of chemical interactions.
The main (mostly local) clinical effects that local darsonvalization manifests: analgesic, vasoactive, trophic, anti-inflammatory, antipruritic, bactericidal (due to the action of ozone).
