What is LLLT?

LLLT gives relief for both acute and chronic pain

LLLT (Low Level Laser Therapy) is the application of red and near infra-red light over injuries or lesions to improve wound / soft tissue healing and give relief for both acute and chronic pain. First developed in 1967, it is now commonly referred to as LLLT.

LLLT is used to: increase the speed, quality and tensile strength of tissue repair; give pain relief; resolve inflammation; improve function of damaged neurological tissue and often used as an alternative to needles for acupuncture.

The red and near infrared light (600nm-1000nm) commonly used in LLLT can be produced by laser or high intensity LED. The intensity of LLLT lasers and LED's is not high like a surgical laser. There is no heating effect.

The effects of LLLT are photochemical (like photosynthesis in plants). Red and near infrared light can affect cell membrane permeability and aid the production of ATP thereby providing the cell with more energy which in turn means the cell is in optimum condition to play its part in a natural healing process.

LLLT devices are typically delivering 10mW - 500mW (0.2 -> 0.01 Watts). The power density typically ranges from 0.05W/Cm2 -> 5 W/Cm2.

LLLT is popularly used for soft tissue injuries, joint conditions, chronic pain, non-healing wounds and ulcers, post-op pain and acupuncture.

This paper from Harvard Medical School reviews the LLLT mechanisms and the biphasic dose response. It summarises the molecular and cellular mechanisms of LLLT, gives a scientific explanation for the biphasic dose response (why a low dose has a stimulatory effect and why a high dose inhibits). Low power densities tend to get better healing and anti-inflammatory effects where higher power densities are more likely to inhibit (which may be useful if you just want an analgesic effect). I have to disclose an interest in this paper because I am a co-author. James Carroll CEO THOR Photomedicine.
