Examination And Validation Of The Fundamental Lower Extremity Mobile Testing System, And Identification Of Best Practice To Mount Synthetic Turf To A Force Platform, Sean Quisenberry
Doctoral Dissertations
Annually, over 4 million high school and college athletes participate in competitive sports played on turf surfaces. Since the introduction of synthetic turf in the 1970s, it has become a common alternative to natural grass playing surfaces. However, athletes playing on synthetic turf has been found to have an increased incidence of lower extremity injury compared to natural grass.
Mechanical surface testing has found that synthetic turf exhibits significantly higher rotational and translational tractions compared to natural grass. The cleat-turf interface is often examined using a force platform, an instrument commonly used in a biomechanical laboratory. Mobile surface testing instruments …
The Influence Of Patellofemoral Pain On Muscle Coordination, Segment Coordination, And Segment Coordination Variability In Runners, Carl Jewell
Doctoral Dissertations
Management of patellofemoral pain syndrome (PFPS) remains a significant challenge in clinical practice and there is a need to understand the mechanisms for altered gait and muscular function which may lead to poor patient outcomes. The overall aim of the three studies in this dissertation was to determine if runners with current PFPS adapt their gait and muscle activation as a result of long-term, daily pain and/or in response to an acute pain flare and exertion during a moderate intensity 21-minute treadmill run compared to healthy controls. In addition, a resolved, asymptomatic PFPS group was included to investigate potential mechanisms …
