Photobiomodulation (PBM Therapy) previously known as Low Level Laser Therapy (LLLT) is the use of red and near infra-red light over injuries or lesions to improve wound and soft tissue healing. This is based on clinical studies shown to reduces inflammation and gives relief for both acute and chronic pain. First developed in 1967 Low-level laser therapy (LLLT) has been actively used for nearly 40 yrs, during which time it has been known to reduce pain, inflammation, and edema.
It also has the ability to promote healing of wounds, including deep tissues and nerves, and prevent tissue damage through cell death.
Much of the landmark research was done by the National Aeronautics and Space Administration (NASA), and these studies provided a springboard for many additional basic science studies.
What is it used for
Photobiomodulation is used to: increase the speed, quality and tensile strength of tissue repair; resolve inflammation and relieve pain (analgesia) in both humans and animals.

PBM is popularly used for soft tissue injuries, joint conditions, neuropathic pain, non-healing leg and pressure ulcers.
What light is used
Initially the use of lasers was used however as technology has improved over the years the use of LED's ( Light Emitting Diodes) has proven just as effective with reduced health risks and costs.
The red and near infrared light (600nm-1000nm) commonly used in PBM can be produced by laser or high intensity LEDs. The intensity of PBM lasers and LED's is not high like a surgical laser. There is no heating effect nor is there any threat to your eyes , in fact studies have show it is actually good for the eyes.
Red Light: Wavelengths in the range 600–700 nm are used to treat superficial tissue
Near Infrared light: 780–950 nm, which penetrate further, are used to treat deeper-seated tissues.
How does it work
The effects of PBM are photochemical (like photosynthesis in plants). When the correct intensity and treatment times are used, red and near infrared light reduces oxidative stress and increases ATP in the mitochondria. This improves cell metabolism and reduces inflammation. When analgesia is required there is a second mechanism which works best when a strong continuous beam is applied.
