Randomized Controlled TrialValidating a nonacupoint sham control for laser treatment of knee osteoarthritis.
The goals of the present study were to evaluate the effect and safety of combined 10.6 microm and 650 nm laser acupuncture-moxibustion on patients with knee osteoarthritis (OA) and to validate a nonacupoint sham control for assessing the effect of point specificity on the treatment. ⋯ Combined 10.6-mum-650-nm laser acupuncture-moxibustion on acupoint ST35 is safe to use and was effective after 2-wk treatment, but not at the 4-wk assessment, in relieving knee OA pain compared to a nonacupoint sham control. A larger clinical trial to verify our findings is warranted.

Randomized Controlled TrialInvestigation of the effect of GaAs laser therapy on lateral epicondylitis.
There are conflicting reports regarding the efficacy of low energy laser therapy in treatment of lateral epicondylitis (LE). Contradictory results are considered to be due to different joint treatment protocols regarding variables such as dose, duration, and frequency. The aim of this study was to investigate the efficacy of gallium-arsenide (GaAs) laser therapy, which was performed with the dose regimen recommended by the World Association for Laser Therapy, in relieving pain and improving functional activities in patients with LE. ⋯ Although low energy laser therapy had no advantage compared to placebo in patients with LE for the short term, a significant improvement, particularly in functional parameters, was achieved in the long term. Laser, which has relatively no side effects, might be included among long-term treatment options for LE.

ReviewLaser photobiomodulation of wound healing: a review of experimental studies in mouse and rat animal models.
This investigation reviewed experimental studies of laser irradiation of wound healing in mice and rats published from 2003 to August 2008, respectively, to assess putative stimulatory effects of this treatment. ⋯ Studies reviewed consistently demonstrated the ability of laser or monochromatic light to photobiomodulate wound healing processes in experimental wounds in rats and mice, and strongly support the case for further controlled research in humans.
