This research investigates whether modifying movement-related sounds can reduce pain and fear in people with knee osteoarthritis. By replacing threatening joint noises with more positive auditory cues, it aims to retrain pain perception, improve rehabilitation outcomes, increase muscle activation, and help patients confidently return to everyday activities.

Why does exercise reduce pain for some people with knee osteoarthritis but not others? By examining psychological factors, educational messaging, and brain stimulation, the studies aim to enhance exercise-induced hypoalgesia and develop effective, drug-free pain-relief strategies that can transform knee osteoarthritis into a manageable condition rather than a lifelong disability.
