Abstract
There are two nonionizing radiations that are used in medical therapy: ultrasound and laser light. The first is mechanical in nature, the second is electromagnetic, nevertheless, they have a common feature: both are coherent. The mechanisms involved in their biological effects are in both cases far from being understood. Recently, it has been claimed by several authors that laser radiation of noninvasive intensities may promote tissue repair. The same was claimed for ultrasound irradiation already more than thrity years ago. With other words, two radiations of basically different nature give identical biological results. The question arises whether this is only a coincidence or there are common features that cause the observed biological effects. In our already reported experiments we have shown that coherence cannot be the reason for the found tissue repairing effects. Now we wish to report on further observations, and compare the results of various researchers using ultrasound and laser, respectively, in their studies to clear up the mechanisms of the biological effects of these radiations.
