Low-level laser irradiation (InGaAlP-660 nm) increases fibroblast cell proliferation and reduces cell death in a dose-dependent Manner

In cell culture, primary fibroblasts treated with laser at 660 nm were shown to increase proliferation and decrease cell death at an irradiance of 2.5 W/cm2 and a fluence of 150 J/cm2.

High power laser therapy treatment compared to simple segmental physical rehabilitation in whiplash injuries (1⁰ and 2⁰ grade of the Quebec Task Force classification) involving muscles and ligaments

Review article thaat concludes that that High Power Laser Therapy is an effective treatment in patients with whiplash injury, compared to conventional simple segmental physical rehabilitation. Compared treatment with laser vs. standard physical therapy and found better results for VAS pain scores with laser treatment.

Inhibitory effects of laser irradiation on peripheral mammalian nerves and relevance to analgesic effects: a systematic review

Systematic review of studies of laser therapy for inhibitory effects on peripheral nerve pain. In 13 of 18 human studies laser therapy was shown to slow conduction velocity and/or reduce the amplitude of compound action potentials.  Several mechanisms for the analgesic effects of laser therapy are also discussed.
