Summary

This study tested whether adding high-intensity laser therapy to exercise can reduce pain and improve muscle strength in people with knee osteoarthritis. 31 adults aged 45-77 with knee pain received either real laser or a sham laser alongside a standard exercise program for four weeks. Researchers measured changes in pain, physical function, and knee strength to see if the laser provided extra benefits beyond exercise alone.
