Ultrasound therapy

In practice, a therapeutic ultrasound in the frequency range of 800-3000 kHz.
the impact of modes of ultrasonic energy can be continuous and pulsed. In the continuous mode ultrasound into a single stream directed to the tissue. In pulse mode, the promise of energy alternating with pauses. Time of delivery of ultrasonic energy and breaks may be different.
Ultrasound has on the mechanical, physical, chemical, and weak heating effect. The mechanical action of ultrasound, due to the variable acoustic pressure causes microvibration, a kind of "micro" fabrics. The thermal effect of ultrasound causes a temperature increase in the tissues, contributing to the expansion of blood and lymphatic vessels, changes in microcirculation. As a result, activated tissue metabolism, manifested anti-inflammatory and resolving action of ultrasound.
Due to physical and chemical action of ultrasound increases the intensity of tissue oxidation-reduction processes, increases the formation of biologically active substances -. Heparin, histamine, serotonin, etc. Ultrasound has a strong analgesic, antispasmodic (eliminates cramps), anti-inflammatory, anti-allergic and tonic effect. It stimulates blood and lymph circulation, regenerative processes, improves the nutrition of tissues. Ultrasound therapy has been widely used in the clinic of internal diseases, diseases of the joints, skin, ear, nose and throat. Ultrasound crushed stones in the gall bladder, kidneys, bladder.
One method is the medical use of ultrasound phonophoresis of drugs. It represents the combined effect of ultrasound and the drug penetrating through the skin and mucous membranes during exposure to ultrasound.
Contraindications for ultrasound therapy are swelling, infection and acute intoxication, blood disease, coronary heart disease, thrombosis, bleeding tendency, low blood pressure, organicheskiezabolevaniya central nervous system, expressed neurotic and endocrine disorders, pregnancy.
