Ultrasonido
Therapeutic ultrasound What is therapeutic ultrasound? It is a form of energy that comes from mechanical vibrations, which spreads out in the form of longitudinal compression waves,Ultrasound therapy is a form of physical therapy that uses sound waves with a frequency higher than our hearing threshold. This noninvasive therapy is also known as boundary surface therapy, meaning its effects will be most pronounced at the existing boundaries of the human body's tissues. Generalities: It is a form of mechanical energy, but we usually classify it as part of the electrophysical group. The normal range of human sound perception is from 16 Hz to approximately 15–20,000 Hz. Beyond this upper limit, mechanical vibrations are known as ultrasound. The frequencies typically used for therapeutic ultrasound range from 1.0 to 3.0 MHz (1 MHz = 1 million cycles per second)....
