Asymmetries In Dynamic Valgus Index After Anterior Cruciate Ligament Reconstruction: A Proof-Of-Concept Study, Kai Yu Ho, Andrew Murata

Physical Therapy Faculty Publications

Individuals with anterior cruciate ligament reconstruction (ACLR) are at a higher risk for subsequent anterior cruciate ligament (ACL) tears. Risk factors for ACL injuries likely involve a combination of anatomical, biomechanical, and neuromuscular factors. Dynamic knee valgus has been indicated as a possible biomechanical factor for future ACL injuries. Given that knee valgus is often accompanied by contralateral pelvic drop during single-leg activities, a dynamic valgus index (DVI) that quantifies combined kinematics of the knee and hip in the frontal plane has recently been developed. As the premise of asymmetrical DVI between limbs in the ACLR population has not been …

Test-Retest Reliability And Minimum Detectable Change For Various Frontal Plane Projection Angles During Dynamic Tasks, David M. Werner, Stephanie Di Stasi, Cara L. Lewis, Joaquin Alberto Barrios

Physical Therapy Faculty Publications

Objective: Establish between-day test-retest reliability metrics for 2-dimensional frontal plane projection angles (FPPAs) during the lateral step-down (LSD), single-limb squat (SLS), single-limb landing (SLL), and drop vertical jump (DVJ).

Design: Test-retest reliability study

Setting: University laboratory

Participants: 20 healthy adults (12 female, age = 23.60±1.93 years old, body mass index = 24.26±2.54 kg/m²) were tested on 2 separate occasions 7-14 days apart.

Main Outcome Measures: Intraclass correlation coefficients (ICC), standard errors of the measurement (SEM), and minimal detectable change (MDC) values across the LSD, SLS, SLL, and DVJ for the following body region variables: trunk, trunk on pelvis, …
