Cold Laser Therapy

Have you considered using cold laser therapy to treat a chronic ailment? Maybe you suffer from Carpal Tunnel Syndrome, lower back pain, osteoarthritis, or ulcers. If you've considered cold laser therapy, otherwise known as Photobiomodulation, low level laser therapy, or LLLT, one might suggest that you endure the pain a little longer before you decide to undergo this treatment.
An article by members of the Department of Dermatology at Northwestern University's Feinberg School of Medicine reports that after researching cold laser therapy for wound healing in both animals and humans, widespread use of cold laser therapy cannot be supported for the treatment of wound healing. The report states that though cold laser therapy had a positive effect in a rodent that was treated for wound healing, the same positive results did not occur when cold laser therapy was tested on pigs. The pig testing is necessary because, as the article states, a pig's skin is the closest resemblance to human skin.
When summarizing the research findings the article states, "(T)o better understand the utility of LLLT in cutaneous wound healing, good clinical studies that correlate cellular effects and biologic processes are needed. Future studies should be well-controlled investigations with rational selection of lasers and treatment parameters."
An extensive report was published by Grace Wang, Medical Director for the Department of Labor and Industries. Wang's article reported on the scientific testing of cold laser therapy to treat Carpal Tunnel Syndrome, various musculoskeletal disorders, and wound healing such as ulcers. Wang's report concluded that cold laser therapy was not effective in treating ankle sprains or wound healing, moderate and inconsistent results in lower back pain and Carpal Tunnel Syndrome treatment, and no substantial evidence resulted in testing cold laser therapy for Osteoarthritis and other musculoskeletal disorders.
A basic source for more information on laser therapy can be found on the website Suite101.com. Suite101.com defines cold laser therapy as "pulsed Infra Red coherent light...produced by a Helium Neon laser." The nature of the therapy is based upon the amount of time that the laser is pointed at the wound, the pulse rate, and the duty cycle.
