QUANTIFYING FRONTAL PLANE KNEE KINEMATICS IN SUBJECTS WITH ANTERIOR KNEE PAIN: THE RELIABILITY AND CONCURRENT VALIDITY OF 2D MOTION ANALYSIS

Background Two-dimensional (2D) analysis has the potential to identify individuals at risk for knee injury by measuring genu valgus during sport related tasks. The reliability of 2D mobile motion analysis in measuring genu valgus during a single leg hop test on individuals with anterior knee pain has not been examined.
