A new review published in Lancet reviewed data from 16 studies including 820 patients regarding the use of low level laser for neck pain. The authors concluded "We show that LLLT (low level laser therapy) reduces pain immediately after treatment in acute neck pain and up to 22 weeks after completion of treatment in patients with chronic neck pain."
This is an important review for two reasons. First, the authors included only high quality, randomized trials that compared the treatment group against a placebo group. Second, there was no conflictive funding for the review. This produces strong evidence for a benefit of low level laser. I've been using a laser in my office for several years now, and it never ceases to amaze me how such a simple device can bring so much relief!
