The use of the terapeutic laser in medicine
VESELÝ, Jan
Modern diagnostics and therapy is nowadays very strongly influenced by technological developments. New discoveries in physics, electronics and other fields lead to search for applications in the medical field. Laser is no exception. It is one of the most important technological discoveries of the late 20th century. A lot of targeted researches and multiple observations demonstrated beneficial effects of the laser radiation on living tissue. Laser was also confirmed to be used in medicine. Recently, laser therapy has been more and more popular. Lasers have found their place and application in almost all areas of medicine, both in treatment and also in research; it has been constantly developing dynamically. Laser Therapy (LLLT) is a branch of phototherapy, which uses light (laser or non-coherent monochromatic beam) for treatment of various diseases. Laser means light amplification by stimulated emission of radiation. This method of treatment is special as it does not lead to serious side effects and treatment does not take so much time to show effectiveness. Laser therapy is very far from practical use of surgical lasers. Laser Therapy (LLLT) is something different containing a lot of scientific utilization characteristics of the laser beam; it uses different colours of the beam to achieve the desired effect for treatment of a particular disease, the correct dosage etc. Surgery uses surgical properties of lasers. These include e.g. surgical knife cutting or tissue welding. Laser therapy possibilities, however, go much further. In this therapy laser is not a mere tool, but a medicine in itself. The power of the therapeutic laser power can be thousands of times smaller and weaker than the power of the surgical one. Many patients still assume that laser therapy consists in the use of surgical lasers, which is, however, not correct. Laser therapy uses non-surgical lasers, which neither cut nor burn. Application of therapeutic laser produces the desired effect in the patient's body by means of the way of cell changes in all cells that are exposed to the beam. It causes increased protein synthesis, immunocorrection, increased ATP production, increased enzymatic activity and circulation, and collagen synthesis. Lasers also regulate lipid metabolism, normalize blood pressure, reduce swelling and inflammation, and reduce pain. Furthermore, leasers have an anti-inflammatory effect, they cause increased cell division and increase immunity against diseases. Lasers have stimulatory, and generally rejuvenilizing and generally healing effects, but when adjusting their dosage they are inhibitory. Thus, using the therapeutic laser brings effective treatment, even if allopathic approach calls many of them incurable.
