Trunk, Hip And Knee Motions During A Step-Down Test And Running In Patellofemoral Pain Individuals, Katie Olinger

WWU Graduate School Collection

Context: A common knee injury in runners is patellofemoral femoral pain syndrome (PFPS). The step-down test (SDT) is used to analyze lower extremity motions in runners with PFPS because kinematics are similar for the SDT and running. Individuals with PFPS often experience altered kinematics when compared to healthy. However, there are no known studies that examine the relationship in kinematics between the SDT and running.

Objective: Examine the relationship between lower extremity kinematics of the knee, hip and trunk in runners with PFPS and healthy controls, during the midstance of running and during a SDT.

Patients or Other Participants: Sixteen …

Joint Motions Of The Knee, Hip, And Trunk During A Single-Leg Step-Down Test And Running, Cody J. Brocato

WWU Graduate School Collection

The purpose of this study was to examine the relationship between kinematic variables at the knee, hip, and trunk during a single-leg step-down test (SDT) and running. Twenty-five healthy subjects (12 male, 13 female) participated in the study; mean ± SD age, 32.8 ± 5.9 years; height, 173.9 ± 8.7 cm; body mass, 70.84 ± 11.3 kg; run volume, 59.5 ± 30.4 km/wk; cadence, 173.1 ± 11.5 steps/min). Dominant leg peak knee flexion was identified during the run (PKF-RUN) and used to find frontal plane knee and hip, and sagittal plane trunk angles. The same treadmill-matched knee flexion angle for …
