Therapeutic ultrasound in the tissue healing

Aiming to minimize the cicatricial treatment period, alternatives have been searched to conventional therapy, among which the therapeutic ultrasound is a practice more and more frequent. However, despite of being used in the treatment of various lesions types, there are still controversies related to its real therapeutical value and the indicated dosimetry for each case. The ultrasound effect on the tissue repair is little understood, and its use is seldom based on the practical experience, what sometimes results in wrong procedures. This review has the objective to show the therapeutic ultrasound information and to reveal the importance of its mechanisms in the tissues in the physical and biological aspects.
