The laser is the latest and most advanced of our light sources. The world laser is an acronym for Light Amplification by Stimulated Emission of Radiation.
Credit for the development of laser theory is generally given to Albert Einstein. In his theory “Zur Quantum Theorie der Strahlung”, published in 1916, he first used the name stimulated emission. Other and more important steps have been taken by Arthur Shawlow, Charles Townes and Theodor Maiman.Maiman presented the first working laser, a ruby laser, at a press conference on 7th July 1960.
In 1966 Mester’s group at the Semmelweiss hospital in Budapest published the first scientific report of the stimulatory effects of non-thermal ruby laser light (694nm) on the skin of rats.
How does low level laser therapy work?
Treatment with laser therapy is not based on heat development but on photochemical and photo biological effects in cells and tissue. There is a primarily response. The cell’s functions are stimulated. The secondary responds are: increased cell metabolism and collagen synthesis in fibroblasts, increased action potential of nerve cells, stimulation of the formation of DNA and RNA in the cell nucleus, release of growth factors.Pain results from trauma, inflammation and/or cellular disruption, malfunction, or less than optimal cellular function. Healing and pain relief come with cellular normalization. Photons enable cells to perform optimally by stimulating them to initiate bio-chemical reactions, which produce enzymes and ATP. Use of low level lasers enhances cellular function and it can also encourage the formation of collagen and cartilage in damaged joints and the repair of tendons and ligaments.
- reduce pain by stimulating cells to produce natural pain killer endorphins
- reduce inflammation
- promote faster healing by stimulating cells to increase the production of healing enzymes
- relax muscles and muscle spasm
- decrease swelling
- stimulate lymphatic drainage
- increase bone repair speed by stimulating fibroblastic and osteoblastic proliferation
- enhance the immune system
- re-energize cell membranes
Is laser therapy safe?
Yes, it is. The patient does not experience any side effects during and after the treatment session.
