A new Australian study appeared in the journal Lancet shows that using cold laser therapy to treat chronic neck pain can be very effective.
Low-level laser therapy, also known as LLLT involves using a laser's light to stimulate tissue repair and ease pain. Lead researcher Roberta Chow of the Brain and Mind Research Institute at Australia's University of Sydney carried out an overview of 16 randomized trials that put this increasingly popular procedure to the test. 820 patients were enrolled in the trials and divided into two groups: one that received either the therapy or other one that received a dummy treatment.
In five trials, the researchers found that patients given LLLT were around four times more likely to have reduced pain compared with a placebo. In the 11 other trials, for which there was a detailed analysis of pain symptoms, LLLT patients reported reductions of chronic pain by around 20 points on a scale of 100 points. The pain reduction continued for up to 22 weeks.
LLLT compares favorably with other drugs and remedies for effectiveness and its side-effects are mild, says the study. The researchers further suggested that low level laser therapy be used in combination with an exercise program for neck pain as well.
