THE EFFECT OF 300MW, 830NM LASER ON CHRONIC NECK PAIN: A DOUBLE-BLIND, RANDOMIZED, PLACEBO-CONTROLLED STUDY

Chow RT et al Pain. 2006 Jun 23
Dr Roberta Chow a GP from Australia conducted a randomized, placebo controlled study on chronic neck pain with laser therapy. 90 patients with chronic neck pain for at least 3 months up to 15 years (mean 11 years) were given 14 treatments with laser over 7 weeks. At 3 months from baseline 84% of patients in the active group achieved a positive response vs only 40% in the placebo group.

The paper has been accepted for publication in the journal "Pain". The abstract is available online now at the following website: www.ncbi.nlm.nih.gov

RETROSPECTIVE STUDY OF ADJUNCTIVE DIODE LASER THERAPY FOR PAIN ATTENTUATION IN 662 PATIENTS

(Shigeyuki Nakaji et al – pub. Photomedicine and Laser Surgery vol. 23 num. 1, 2005)
Subjects were 1087 patients treated between April 1992 to august 1995. The efficacy rating immediately after treatment was 46.8% in men and 47% in women, rising to 73.3% in men and 76.8% in women at time of survey (1996). Conclusion: Infrared Diode Low Level Laser Therapy (Photomedicine) is considered safe, effective and side effect free making an ideal adjunctive therapeutic modality for intractable chronic pain.
