Cold
laser therapy (low-level laser therapy, LLLT) utilizes low-intensity laser light to irradiate body tissues, achieving therapeutic effects through biostimulation. Its mechanisms of action include: photochemical bioeffects, stimulating mitochondrial activity to promote cell repair; anti-inflammatory effects, reducing the release of inflammatory factors; analgesic effects, reducing pain mediators and promoting endorphin secretion; and increased blood circulation, improving local oxygen and nutrient supply.
Specific Mechanisms of Action
Photochemical Bioeffects: Laser photons are absorbed by cells, stimulating mitochondrial activity and increasing ATP production, which is required for cellular metabolism, thereby accelerating cell repair and regeneration.
Anti-inflammatory Effects: Laser irradiation inhibits the release of inflammatory factors and reduces the intensity of the inflammatory response.
Analgesic Effects: Laser light reduces the release of pain mediators and stimulates the body's production of endogenous analgesics (such as endorphins), thereby relieving pain.
Increased Blood Circulation: Laser light dilates blood vessels, increasing local blood flow, bringing more oxygen and nutrients to damaged tissues and promoting tissue repair.
Applications
Main Applications: Pain relief, tissue repair, and inflammation reduction.
Other Applications: Stimulating stem cell proliferation, for hair loss treatment, etc.
Safety Precautions
Avoid eye exposure: Wear protective glasses during treatment to avoid direct laser exposure to the eyes.
Contraindications: Not suitable for use on cancerous areas, the abdomen of pregnant women, or the thyroid area.
Treatment Procedure: Generally painless and comfortable for the patient.
