Can a simple pressure-sensing device beat foam rolling for knee arthritis pain?

This trial tests whether pressure biofeedback training—using a device that shows how hard you press—can reduce pain and improve muscle function better than bolster foam rolling in people with knee osteoarthritis. Forty-eight participants with moderate knee arthritis will do one of the two exercises three times a week for eight weeks. Researchers will measure pain, daily function, and quadriceps muscle activation at several points to see which approach works best.
