Ultrasounds
Ultrasounds are acoustic vibrations with a frequency higher than 16,000 Hz, ranging from 0.2 to 3 W / cm2, which are not perceptible to the human ear and spread as compression and decompression waves, transmitted through a retained head Perpendicular to the area to be treated, passes on the skin to which an ecoconductive gel was previously applied.
They are used in physiotherapy to increase tissue metabolism and cellular activity, increase blood flow to vasodilatation, capillary permeability, pain threshold, extensibility, and elasticity of the fibrous tissue.
