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.

This research develops a robotic system capable of reproducing real-world knee motions and ACL injury mechanisms in human cadaver knees. The platform enables realistic testing of injury-prevention technologies, improves understanding of ACL rupture biomechanics, and may help reduce injury risk, particularly among women who experience higher ACL injury rates.
