The method of physiotherapy, which uses the action of a pulsed current of high voltage and frequency, but low power, is called darsonvalization. This method of exposure was discovered in 1891 by the French physiologist-scientist Jacques d'Arsonval. He revealed the beneficial effects of such a current on human health. The method is applicable in the treatment of skin diseases, genital organs, nervous system.
The first darsonvalization apparatus was created 120 years ago. Its use proved the effectiveness of the treatment, and it was most widely used. In the 80s, such a device was available in any physiotherapy room in the USSR. Darsonvalization was included in the treatment regimen for many diseases, but it was especially widely used in cosmetology.
How the method works
High-frequency currents can irritate the sensitive nerve endings in the skin, and by doing so they activate blood circulation. The vessels are first sharply spasmodic, and then expand for a long time. Cell nutrition and respiration are improved, local immunity is activated. This occurs due to the isolation of prostaglandins and cytokines. Skin turgor rises. White blood cells begin to intensively destroy pathogenic microorganisms, which many times accelerates recovery.
Darsonval acts in a variety of ways:
- Contact method - the electrode glides directly on the skin.
- The non-contact method is a few mm from the skin. With this arrangement of the electrode, there may be a different distance to the skin. At a distance of 2-3 mm there is a whole sheaf of spark discharges - slipping of cold sparks. They also irritate nerve endings, but their excitement is transmitted to the spinal cord. After that, diseased organs react and pain is blocked - this is a reflex reaction.
- The point method of application - the electrode is above the skin at a distance of 1 cm - the sparks are long and accompanied by a crack. This method removes warts.
- Bactericidal effect - charged ions strike microbes and they die. Electrical discharges produce ozone and nitrogen oxides (remember the air during a thunderstorm). Ozone itself has a bactericidal effect. Thanks to this effect, small pimples and pustules dry out, and large, not ripened abscesses are opened in the next day.
When conducting a darsonvalization session, the patient does not feel any unpleasant sensations at all. Only a slight warmth is felt.
Indications for darsonvalization
Darsonval is indicated in the following cases:
- Pathologies of the peripheral nervous system: paresthesia, neuralgia, the effects of neuritis, radiculitis and osteochondrosis.
- CNS disorders: migraine, neurosis, insomnia, dystonia, enuresis, neurodermatitis.
- Skin pathologies: acne, diathesis, dermatoses, inflammatory infiltrates, increased activity of the sebaceous glands.
- Inflammation of the subcutaneous fat, known as cellulite.
- With such circulatory disorders as: varicose veins, trophic ulcers, fungal skin lesions.
- ENT diseases: perceptual hearing loss, stomatitis, rhinitis, sinusitis.
- Genital diseases: impotence, prostatitis, genital inflammation, dry vagina.
The effects of darsonvalization
In addition to improving the condition of the skin, increasing its turgor and local immunity, allergic rashes and itching are reduced, a bactericidal effect and anti-inflammatory are manifested, hair growth is stimulated by improving the nutrition of hair follicles. It should be noted that with hair the result is so pronounced that a side effect may appear in the form of increased vegetation on the skin.

- hypertrichosis
- bleeding
- pregnancy (risk of developing congenital abnormalities in the fetus due to the electromagnetic field).
Relative contraindications:
- skin damage in the affected area;
- pain on the electrodes;

Side effects of the procedure
Basically, this is an increased growth of facial hair and the risk of a recurrence of a stroke if contraindications are not observed. Darsonvalization is now available at home if you buy a portable device.

Instructions for use
Instructions darsonval "Spark ST-117" gives a step-by-step guide to use.
- When connecting to the mains, check for damage or contamination on the device.
- The discharge force regulator should be in the off position.
- Next, you need to insert the desired electrode into the housing base, but without sharp efforts. It should be well fixed. Only then can the device be connected to the network.
- First, make sure the device is operational - to do this, put the regulator in the middle position. An orange or purple glow should appear.
- Now turn off the device. If the glow does not appear at the end of the nozzle, try to force the ionization again. To do this, the regulator must be turned to the right to the extreme maximum position (max), and the electrode should be applied to the metal surface. It can be any, but always grounded (but do not touch it).
- The discharge should appear within 5 minutes. If the glow did not appear, the device must be carried in for repair - it is faulty.
- If everything is normal - bring the electrode to the problem area, but do not apply to the skin. Then you need to turn the knob slowly until you feel a slight tingling sensation. Now you can work - the device is ready. Changing nozzles is also necessary when the device is disconnected from the network.
- After the procedure, the electrodes must be wiped with a cotton swab with alcohol. In extreme cases, wipe with a well-wrung cloth after wetting with a detergent (neutral).
- Dry the device, pack it in a case. Perform all manipulations when disconnected from the network.
