Ultrasound has on the body mechanical, physical, chemical and weak thermal effect. It stimulates blood and lymph circulation, reduction processes, improves tissue nutrition. Due to physical and chemical effects of ultrasound increased the intensity of the tissue redox processes, increases the formation of biologically active substances - heparin, histamine, serotonin, etc. Electrotherapy. Indications for the use of UV radiation are acute and chronic diseases of the joints, respiratory and female Do not repeat organs, skin, peripheral nervous system injuries (local exposure), and as compensation ultraviolet failure to improve resistance to various infections, hardening, prevention of rickets, in tuberculous lesions of bones. Dosage effects on the body electric current, as well as electrical, magnetic or electromagnetic fields. Their use promotes epithelialization of the wound surface, and the regeneration of nerve and bone tissue. Sensitivity to ultraviolet rays is increased in children, especially in an early age. Therapeutic effect of infrared radiation by the mechanism of its Hemophilia effect - it accelerates the regression of inflammatory processes, improves tissue regeneration, local resistance to infection control and protection. Time limit for receipt of ultrasonic energy and a pause may be different. Mechanical action of ultrasound caused by ac acoustic pressure causes micro vibration, a sort of "micro-massage" fabrics. Therefore, their direct influence restricted to surface layers of irradiated skin and mucous shells. Ultrasound therapy has been widely applied in the clinic of internal medicine at diseases of the joints, skin, ear, nose and throat. Most sensitive to the ultraviolet (photosensitivity), skin surface of the body, the least - the skin of the limbs. The ultrasound has a strong analgesic, antispasmodic (removes spasms), anti-inflammatory, antiallergic and tonic effect. They include in the muscle, glandular tissue, and body fluids (blood, lymph, intercellular fluid, etc.). In pulsed mode promise of energy interspersed with pauses. Thus, photosensitivity of the skin back of the hand and foot by 4 times lower than the abdominal skin and the lumbar region. Leather palms and soles of the least sensitive. The therapeutic use ultrasound in the frequency range 800-3000 kHz. Modes of action of ultrasonic energy can be continuous and pulse. Thermal effect of ultrasound causes temperature rise in tissues, helping to expand the blood and lymphatic vessels, changes in microcirculation. The use of ultraviolet light for therapeutic purposes in a well-selected individual dose, and clear monitoring gives a high therapeutic effect in many diseases. However, ultraviolet rays are least depth of Cytolysis into the tissue - only 1 mm. Ultrasound crushed stones in the gall bladder, kidneys and bladder. In the tissues of the human body contains both colloids (proteins, glycogen Other krupnomolekulyarnye substance) and salt solutions. It represents the combined effect of ultrasound and drugs that penetrate through the skin Right Atrium mucosa during exposure to ultrasonic vibrations.
