Meta-analysis of pain relief effects by laser irradiation on joint areas
Meta-analysis of 22 trials of LLLT on joint pain. When the authors only considered trials with dose range predicted by Bjordal et al. in 2003 and WALT, the results were more positive. They concluded that laser therapy on joints reduces pain more reliably if treatment dose is in the therapeutic dose window. The review concludes that laser therapy on the joint reduces pain in patients.
