A study by Michael R. Hamblin looked at how near-infrared (NIR) light, a type of low-level laser therapy, could help treat osteoarthritis (OA). Using a rat model of OA, the researchers applied NIR laser light to the affected joints and found that it reduced inflammation and pain. The laser treatment helped lower the number of inflammatory cells in the joints and decreased levels of harmful molecules that cause swelling and pain. Interestingly, the treatment worked best at a lower power (50 mW) compared to a higher power, suggesting that smaller doses of light might be more effective for reducing inflammation.
These results are promising for people with osteoarthritis because NIR light therapy may offer a non-invasive way to reduce joint pain and inflammation without the side effects of traditional medications, like painkillers or anti-inflammatory drugs. Although the study was done in rats and more research in humans is needed, the findings suggest that infrared light could be a helpful treatment for arthritis in the future. It’s a safe option that could help manage symptoms and improve quality of life for people suffering from joint pain.
