ACL Patients' fear of movement under the microscope: is the standard test missing the mark?
NCT ID NCT07190456
First seen Jun 27, 2026 · Last updated Sep 11, 2026 · Updated 2 times
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.
