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.

    Dr. Williams learned the benefits of chiropractic care as a young man, having sustained a low back injury from an accident on an all-terrain vehicle when he was twelve years old. By suffering this injury and the subsequent treatments, he became aware of the benefits of chiropractic care and solidified his desire to become a chiropractor. Soon after graduating in 1998 he started practicing with his father, Dr. Marc Williams who retired from the practice in 2001.

I had back surgery in 2011. I come in the office and get the laser treatment and love it. For me it really helps with the soft tissue giving much needed relief. It feels good and it’s effective- Highly recommended!

Ronald Hunter

Great Place!!! Friendly and caring staff. Was having disk pain that was impacting my nerves and legs. Aileen does a great job applying the laser treatments. Started receiving treatments with the last two weeks and the majority of the pain is gone.

Found them because of extreme pain in my hip. Turned out I had 2 vertebrae turned and disks compressed. They are getting it fixed. Pain is gone.Love the staff. Victoria and Aileen take great care and make me feel very welcome every time.

P and L Center doctors and staff are knowledgeable, friendly and caring. They listen and, having heard, respond to concerns to customize treatment to meet my individual needs. With these professionals as partners, I find myself increasingly hopeful that I will be able to more successfully manage my health issues and improve the quality of my life.

Robin Reynolds

I started this treatment and could barely walk into the office. I was in bad shape from messing my lower back up. It’s been 1.5 weeks and I’m 1000% better. In another week I should be as good as new or better!! Loved it!

Carla Tolley

I have truly enjoyed getting to know all the professionals at my Pain and Laser Center in Greensboro. From the first day I came in everyone remembered my name and the attention was remarkable. The nurses are the best!

Cynthia Leonard

Friendly and knowledgeable staff - Aileen the laser technician is wonderful as is Dr. Williams. I came here in September with debilitating pain from an existing condition worsened by a slip and fall. The treatment plan designed for me has effectively, and happily, got me back to 100%. I highly recommend this center!

Jayne Calicchio

Hi, I was unfortunately involved in a car accident. My wife ask some friends for recommendations and the pain and laser center came highly recommended. I also visited my primary care the day after the accident and they also recommended pain and laser center. I had never been to a chiropractor. My primary care called and they opened a spot for me to come the same day. I have to say I was a bit skeptical at first but after a few visits and adjustments I am now a believer. I have made steady progress over the past 3 weeks. The treatments are great. This office has a very nice, modern, clean and relaxing atmosphere. The professional staff is wonderfully positive. I highly recommend this place of business if you have been in an accident or maybe have issues with pain in your back. Special thanks to Dr. Stafford.
