Low Level Laser Therapy (LLLT)
What is LLLT?
Low Level Laser Therapy (LLLT) sometimes known as Low Level Light Therapy or Photobiomodulation (PBM) is a form of medicine that applies low-level (low-power) lasers or light-emitting diodes (LEDs) to the surface of the body. Whereas high-power lasers are used in laser medicine to cut or destroy tissue, it is claimed that application of low-power lasers relieves pain or stimulates and enhances cell function. The effect is photochemical not thermal. The light triggers biochemical changes within cells and can be compared to the process of photosynthesis in plants, where the photons are absorbed by cellular photoreceptors and triggers chemical changes.
Light with a wavelength in the red to near infrared region of the spectrum (660nm–905nm), is generally employed because these wavelengths have the ability to penetrate skin, and soft/hard tissue and are proven in clinical trials to have a good effect on pain, inflammation and tissue repair. The result is a reduction of inflammation, pain relief and accelerated tissue regeneration.
LLLT is beneficial for pain relief and can accelerate the body’s ability to heal itself. LLLT has a long history and strong basic science evidence, which supports its use in pain management and healing potential. It has few side effects, is pain free, and is well tolerated.
