Laser therapy shows promise for easing knee arthritis pain

This study tested whether high-intensity laser therapy (HILT) combined with exercise reduces pain and improves muscle strength in people with knee osteoarthritis. Thirty-one adults aged 45 to 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.
