Local darsonvalization is a method of local exposure to alternating electric current of appropriate parameters, carried out using 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 to a certain area of the patient's skin or mucous membranes.
Local darsonvalization uses a current of up to 0.02 mA; voltage of up to 25 kV; current oscillation frequency of 50-110 kHz, modulated by bell-shaped pulses; pulse repetition frequency of 50 Hz; pulse duration of 50-100 μs.
The specific features of the factor's action are caused by the occurrence of an electric discharge between the vacuum electrode and the patient's skin or mucous surfaces, which has a superficial irritating and even cauterizing effect, and also initiates pronounced electrodynamic changes (displacement currents) in the superficial tissues with subsequent conformational rearrangements of the corresponding structures. In addition, as a result of the electric discharge between the electrode and the skin, ozone and nitrogen oxides may form, which in turn affect the receptors of the skin and mucous membranes based on chemical interactions.
The main (mainly local) clinical effects that local darsonvalization exhibits are: analgesic, vasoactive, trophic, anti-inflammatory, antipruritic, bactericidal (due to the action of ozone).
Equipment: Iskra-1, Iskra-2, Impuls-1, SPARKY, etc.
