Efficacy of low-level laser therapy in the management of neck pain: a systematic review and meta-analysis of randomised placebo or active-treatment controlled trials
Review of laser therapy for neck pain published in a top-tier medical journal. Sixteen RCTs including 820 individual patients were included in the review. Laser therapy was found to immediately reduce neck pain and maintained results up to 22 weeks after completion of treatment. Also, most statistical heterogeneity disappeared when Chow excluded studies with small doses or flaws in treatment procedure.
