TOP 9 BIOLOGICAL EFFECTS OF LASER THERAPY
DECREASED INFLAMMATION AND SWELLING Laser therapy reduces inflammation through several mechanisms especially via the reduction of pro- inflammatory mediators. Facilitating lymphatic drainage can significantly reduce swelling as well. As a result, inflammation, erythema, bruising, and oedema are reduced. ANALGESIC EFFECT Laser therapy of diseased and damaged tissue produces a suppression of hypersensitive nociceptors, normalisation of the membrane firing threshold, and an increased release of tissue endorphins, amongst other mechanisms. In addition to the reduction in inflammation, the result is a decreased patient perception of pain. ACCELERATED TISSUE REPAIR AND CELL GROWTH Photons of light from lasers penetrate deeply into tissue and accelerate cellular reproduction and growth. Laser light increases the energy available to the cells so that they can take on nutrients and get rid of waste products more quickly. IMPROVED VASCULAR ACTIVITY Laser light significantly increases the formation of new capillaries in damaged tissue. This speeds the healing process, resulting in more rapid wound closure and improving blood supply to areas with poor circulation or chronic wounds. TRIGGER POINTS AND ACUPUNCTURE POINTS Laser therapy treats muscle trigger and acupuncture points without mechanical invasion to aid in providing musculoskeletal pain relief. REDUCED FIBROUS TISSUE FORMATION Laser therapy reduces the formation of fibrous scar tissue, favouring more appropriate deposition and orientation of collagen fibers leading to better tensile strength in healed tissues. IMPROVED NERVE FUNCTION Slow recovery of nerve functions in damaged tissue may result in numbness and impaired limbs. Laser therapy accelerates nerve cell regeneration. IMMUNOREGULATION Therapy laser photons have an effect on the immune system’s status through modulation of the immune response. FASTER WOUND HEALING Laser light stimulates fibroblast development. Fibroblasts produce collagen, which is predominant in wound healing in damaged tissue. Collagen is the essential protein required to replace old tissue or to repair tissue injuries. As a result, laser therapy is effective on open wounds and burns.
