Abstract

Background. Ultrasounds (UD) are used in medicine from about 70 years. The biological mechanism of ultrasounds is a complex and versatile process and the energy, if absorbed in adequate amount, may activate many reactions in tissues. UD have thermal and post-thermal effects and are regarded as the most important deeply thermal procedures. Thermal effects can be easily observed as tissue temperature increases, but not all results of UD can be explained as only influence of thermal factor. Currently, we are looking for an explanation of these effects in mechanical and physiochemical factors which closely coexist. Find the occurrence changes of the skin temperature under the influence of ultrasounds with use continuous and impulse wave and verify if these waves develop the same or different reflectoric impact. Material and method. This study covered 30 people. In few days-long intervals every of the examined patient was tracted with local ultrasounds used continuous and impulse waves. Additionally there was used pyrometr for non-contact measurement of temperature in order to record post-operative changes of skin surface temperature. Results. This study suggest that under the influence of a single ultrasound application with used continuous and impulse wave, immediately after treatment there is observed increase of skin temperature which lasts to the end of measurement. Changes of the skin temperature could be observed in treated and reflectoric areas.Conclusions. Study show that, after ultrasounds therapy is observe the skin temperature increases. Changes of the skin temperature confirm these effects in the treated please and reflectoric areas.
