The effect of low-level laser in knee osteoarthritis: a double-blind, randomized, placebo-controlled trial
Study designed to examine pain-relieving effect of low-level laser therapy (LLLT) and possible microcirculatory changes measured by thermography in patients with knee osteoarthritis (KOA). Treatments were delivered twice a week over a period of 4 wk with a diode laser (830 nm, cw, 50 mW) in skin contact at dose of 6 J/point. Results show that LLLT reduces pain in KOA and improves microcirculation in the irradiated area.
