The Ultimate Guide to Red Light Therapy
This study builds on previous research by the same group, which showed that this type of laser therapy can
also improve blood flow and reduce scarring in arthritic joints.11 Overall, these findings suggest that low-level
laser therapy, particularly using near-infrared light, could be a promising option for treating osteoarthritis.
However, it‘s important to remember that this study was conducted in rats, and further research is needed to
confirm these benefits in humans.
