Biological Effects of Laser Therapy on the Human Body
ACCELERATED TISSUE REPAIR AND CELL GROWTH
Photons of light from lasers penetrate deeply into tissue and accelerate cellular reproduction and growth. The laser light increases the energy available to the cell so that the cell can take on nutrients faster and get rid of waste products. As a result of exposure to laser light, damaged cells are repaired faster.
Laser Therapy has a beneficial effect on nerve cells. It blocks pain transmitted from these cells to the brain, which decreases nerve sensitivity. With reduced inflammation, there is less edema (swelling) and less pain. Another pain blocking mechanism involves the production of high levels of pain killing chemicals such as endorphins and enkephalins from the brain and adrenal gland.
Laser Therapy has an anti-edema effect as it causes vasodilation and activates the lymphatic drainage system which drains swollen areas. As a result, there is a reduction in swelling caused by bruising or inflammation.
FASTER WOUND HEALING
Laser light stimulates fibroblast development in damaged tissue. Fibroblasts are the building blocks of collagen, which is the essential protein required to replace old tissue or to repair tissue injuries. As a result, Laser Therapy is effective post-surgical and in the treatment of open wounds and burns.
Laser light has a direct effect on immunity status by stimulating immunoglobins and lymphocytes. Laser emissions are absorbed by chromophores (laser absorbing molecules) that react to laser light. Upon exposure to the laser, the enzyme flavomononucleotide is activated and starts the production of ATP (adenosine-triphosphate), which is the major carrier of cell energy and the energy source for all chemical reactions in the cells.
IMPROVED NERVE FUNCTION
Slow recovery of nerve functions in damaged tissue can result in numbness and impaired limbs. Laser light speeds up the process of nerve cell reconnection and increases the amplitude of action potentials to optimize muscle healing.
IMPROVED VASCULAR ACTIVITY
Laser light will significantly increase the formation of new capillaries in damaged tissue, which speeds up the healing process, closes wounds quickly, and reduces scar tissue. Additional benefits include acceleration of angiogenesis, which causes temporary vasodilation and increases the diameter of blood cells.
INCREASES METABOLIC ACTIVITY
Laser Therapy creates higher outputs of specific enzymes, greater oxygen, and food particle loads for blood cells.
REDUCED FIBROUS TISSUE FORMATION
Laser Therapy reduces the formation of scar tissue following tissue damage from cuts, scratches, burns, or surgery.
TRIGGER POINTS AND ACUPUNCTURE POINTS
Laser Therapy stimulates muscle trigger points and acupuncture points on a non-invasive basis providing musculoskeletal pain relief.
