The BionMed® clinical system consists of a handstick with three frequencies for manual control of the ultrasound. Ultrasound produces a variety of physiological effects and is thus suitable for supporting the body’s self-healing powers. In addition to the direct effect on the tissue through mechanical pressure and particle movement, an additional “internal” mechanical effect of triggered secondary effects, such as cavitation and micro-currents, is described, which can also be referred to as “micro-massage”. Undesirable excessive local overheating, e.g. on the periosteum, can be avoided by correct application. Due to the procedure, superficial skin heating may occur.
