Laser heat therapy may boost knee pain relief when added to exercise

This study looks at whether adding a special laser treatment (CO2 infrared laser moxibustion) to a standard exercise program can reduce knee pain and improve function in people with knee osteoarthritis. About 68 adults aged 55 to 65 with knee arthritis will be randomly assigned to either exercise alone or exercise plus the laser treatment for 8 weeks. Researchers will measure pain, knee movement, and cartilage changes over 6 months to see if the laser provides extra benefit.
