Low-level laser therapy (LLLT; 780 nm) acts differently on mRNA expression of anti- and pro-inflammatory mediators in an experimental model of collagenase-induced tendinitis in rat

A rat model of induced tendonitis was used to evaluate the effect of laser therapy on inflammatory signaling.   The laser group had significantly lower mRNA for IL-6, COX-2 and TGF-β than control animals in both acute and chronic phases.  Laser therapy significantly reduced mRNA TNF-α only at the chronic phase. Laser therapy is effective for [...]

Low level laser therapy for sports injuries

Report on the use of laser therapy for sports injuries. For 10 years, the hospital had used laser therapy for treatment of sports injuries and report that 10 W is more effective than 150 mW and 1 W laser therapy.

Effectiveness of low-level laser therapy in temporomandibular disorder

Randomized placebo-controlled study to investigate the efficacy of LLLT in TMD. Patients in the treatment group received 15 treatments of 3 J/cm2 at 904nm.  Both groups improved in all measures over the study period. The laser group had significantly better improvement in the number of tender points and all range of motion measures.

Changes in absorbance of monolayer of living cells induced by laser radiation at 633, 670, and 820 nm

Absorption changes in HeLa cells were evaluated from 530-890 nm. Cytochrome c oxidase becomes more oxidized (implying increased cellular oxidative metabolism) at all wavelengths used. This study supports the hypothesis that the mechanism of photobiomodulation is related to the chromophore cytochrome c.
