Abstract

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. To assess the reliability and concurrent validity of 2D mobile motion analysis and compare it to visual observation while analyzing dynamic genu valgus during a single leg hop test in subjects with anterior knee pain. Cohort study; repeated measures. Nineteen subjects experiencing anterior knee pain completed a single leg hop test with both lower extremities. Two investigators independently estimated the degrees of genu valgus with visual observation alone during the subjects' single leg hop. After the visual estimation, the investigators watched the video again using the 2D Spark Motion Pro™ application to pause the video and measured the amount of knee valgus with a virtual goniometer tool on the application. Interrater reliability was calculated using intraclass correlation coefficients (ICC) model 2, k and intrarater rater reliability using model 3, k. Minimal detectable change, concurrent validity and limits of agreeme...Continue Reading
