Abstract

The work presents the results of the low-level laser therapy (LLLT) of two groups of volunteers with a variety of conditions performed with a GaAs-system. The volunteers were randomly selected among the patients who were usually treated by conventional therapy that included massage and acupuncture needles. The LLLT was proposed to the first group as extension of conventional treatment. The second group underwent only the LLLT. The effectiveness of the therapy was graded under four categories. Short-term and long-term side effects as well as conditions responding only to LLLT were recorded. The successful treatments were up to 70% for both groups, which coincided with the result of the control group treated by the conventional therapy. For optimization of the light delivery, the spatial maps of the absorbed dose in a homogeneous medium, both in the proximity of the light source and at a distance from it, were compared for collimated and divergent light beams using a reduced variance Monte-Carlo code.
