Thor Low level Light Therapy (LLLT) is used to:
The red and near infrared light (600nm-1000nm) commonly used in LLLT can be produced by laser or high intensity LEDs. The intensity of LLLT lasers and LED's is not high like a surgical laser. There is no heating effect, this is why they are called cold lasers.
The effects of LLLT 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. This improves cell metabolism and reduce inflammation. These effects can be enhanced with pulses however when analgesia is required there is a second mechanism which works best when a strong continuous beam is applied.
LLLT is popularly used for soft tissue injuries such as:
At Riverside Chiropractic Group we have two different types of probes: LED and LASER. The combination of both LASERs and LEDs deliver photons to both the superficial and the deep tissue. This means that our therapy is the best available and the most effective for natural healing.
LLLT works predominately on a protein in mitochondria (cytochrome c oxidase) to increase ATP and reduce oxidative stress. A cascade of mitochondrial and intracellular downstream effects lead to improved tissue repair and reduced inflammation.
Lasers and LED's produce intense beams of light at specific wavelengths. When the right wavelength at the right intensity is used at the correct anatomical location for the right amount of time you can stimulate repair, resolve inflammation and reduce pain.

There are many studies. Here are six strong systematic reviews which have found in favour of LLLT.
BMJ sports medicine journal - systematic review of surgical and conservative interventions for frozen shoulder found strong evidence for LLLT. Click here for more information.
The International Association for the Study of Pain - a global task force on musculoskeletal pain, found strong evidence for Low Level Laser Therapy on myofascial pain syndrome. Click here for more information.
