Summary

This study looks at how people who have had ACL surgery experience fear of movement. Researchers want to see if the usual questionnaire captures this fear accurately, or if watching and anticipating specific sports moves gives a better picture. About 21 participants will have their heart rate, sweat response, and walking patterns measured while they think about or see movements that scare them.
