New study shows scientific benefit of laser therapy


Low-level laser therapy (LLLT) is a form of light therapy that triggers biochemical changes within cells. Photons are absorbed by cellular photoreceptors, triggering chemical alterations and potential biochemical benefits to the human body. LLLT has been used in pain management for years and is also known as cold laser therapy, which uses low-frequency continuous laser of typically 600 to 1000 nm wavelength for pain reduction and healing stimulation. Many studies have demonstrated analgesic and anti-inflammatory effects provided by photobiomodulation in both experimental and clinical trials.


The purpose of this research article was to present a summary of the possible pain management benefits of LLLT.


In cold laser therapy, coherent light of wavelength 600 to 1000 nm is applied to an area of concern with hope for photo-stimulating the tissues in a way that promotes and accelerates healing. This is evidenced by the similarity in absorption spectra between oxidized cytochrome c oxidase and action spectra from biological responses to light. LLLT, using the properties of coherent light, has been seen to produce pain relief and fibroblastic regeneration in clinical trials and laboratory experiments. LLLT has also been seen to significantly reduce pain in the acute setting; it is proposed that LLLT is able to reduce pain by lowering the level of biochemical markers and oxidative stress, and the formation of edema and hemorrhage. Many studies have demonstrated analgesic and anti-inflammatory effects provided by photobiomodulation in both experimental and clinical trials.


Based on current research, the utilization of LLLT for pain management and osteoarthritic conditions may be a complementary strategy used in clinical practice to provide symptom management for patients suffering from osteoarthritis and chronic pain.

Learn Who We Are

  • Dr.
    Aaron Williams
    DC, LIFE University

    Dr. Williams DC fractured his back at the age of 12 years old due to a ATV accident while living on his family farm in Iowa. Today, he continues to live with a non-healing fracture (Grade 2 Spondylolisthesis) of the L5 vertebrae without surgery largely due to the results of the class IV laser therapy he received himself. Seeing how the class IV laser therapy helped him continue to be healthy, extremely physically active and pain free without surgery, Dr. Williams DC started studying how cold laser could help his patients more effectively than just the use of class IV laser. He found that the lack of oxygen in our bodies as we age was a big factor in the tissue death (soft tissue nerves etc.). Due to this finding oxygen related techniques are used to improve the results a patient needs when dealing with long term neuropathy, disc herniations, meniscus damage and overall soft tissue damage from past surgeries. He created the LASERA technique and has had such amazing success reducing patients pain and dysfunction that he wants to 'shout from the tree tops.'

    After growing up on St. Simons Island, Georgia, I completed my undergraduate degree in Biology and Chemistry from Lenoir Rhyne University in Hickory, North Carolina. During my time at LR I spent four years playing football as a Defensive and Offensive Lineman. I then went on to graduate Magna Cum Laude from Life University in Marietta, Georgia earning my Doctorate of Chiropractic. I specialize in chiropractic care for children and adults. I utilize a “whole person approach” to wellness, looking for the cause of symptoms and eliminating it naturally.

    In my spare time I enjoy playing golf, CrossFit, and spending time with my wife and dog. Fun fact I’ve lived in five states and moved to Greensboro in 2016! I love playing and watching sports, especially when I get to cheer on the Pittsburgh Steelers or the University of Georgia.
