Low-Level Laser Therapy also is known as Cold Laser Therapy, and phototherapy involves the application of low power coherent light to injuries and lesions to stimulate healing and reduce pain. It is used to increase the speed, quality and strength of tissue repair, resolve inflammation and give pain relief. LLLT has been found to offer superior healing and pain relieving effects compared to other electrotherapeutic modalities such as ultrasound, especially in chronic problems and in the early stages of acute injuries. LLLT is a complete system of treating muscle, tendon, ligament, connective tissue, bone, nerve, and dermal tissues in a non-invasive, drug-free modality. How does LLLT work? Low-Level Lasers can strengthen and heal damaged cells. Using photochemical processes, laser light inserts bio-photons into damaged cells. The cells begin to produce energy (ATP), which improves their function, assists their division, strengthens the body’s immune system, and pain disappears. If damaged cells have died, the bio-photons help the division of neighboring cells, generating new tissues, and thus bring about healing. LLLT promotes healing in many conditions because it penetrates the skin, increases the ATP and activates enzymes in the targeted cells. Growth factor response within the cells and tissue as a result of increased ATP and protein synthesis. Improved cell proliferation. Pain relief as a result of increased endorphin release. Strengthening the immune system response via increasing levels of lymphocyte activity.
