Cold Laser Therapy
The health benefits of cold laser therapy can be roughly divided into three categories:
1) Reduce inflammation
2) Reduce pain
3) Accelerate tissue repair
Immediately after an acute injury, the body undergoes a complex series of reactions designed to stop bleeding and initiate the tissue repair process. This process normally includes edema, inflammation, and pain. These reactions are designed to protect the damaged area while the body repairs itself. Laser therapy has been shown to reduce inflammation by increasing the amount of vaso-dilating and anti-inflammatory compounds such as prostaglandin PGI2. It has also been shown to reduce Interleukin 1 (IL-1), a pro-inflammation component that is connected to inflammatory diseases like Rheumatoid arthritis.
Laser treatments have been shown to stimulate increased levels of beta-endorphins. B-endorphins are neuropeptides that serve as natural analgesics to reduce pain.
Accelerate Tissue Repair
To speed tissue repair, laser light affects the mitochondria. The mitochondria is the part of the cell responsible for producing ATP (adeno-triphosphate); the chemical energy of the cell. Laser light has been shown to greatly accelerate the production of ATP, thus speeding up the overall activity of the cell. In cells responsible for repairing tissue, including bone, muscle, ligament, skin, and even nerves, this results in an increase rate of repair.
Combining Ancient Chinese Medicine with Modern Technology: Laser Acupuncture
An increasing body of evidence suggests that laser treatments on specific acupuncture points can stimulate a similar effect as acupuncture needles. Successful studies include laser acupuncture as a means to successfully treat osteoarthritis of the knee to the use of laser acupuncture in the ears to help smoking addiction. This discovery provides a unique alternative to patients who are terrified of needles, but still seek the powerful healing benefits of acupuncture.
