Ankle-Knee Initial Contact Angle And Latency Period To Maximum Angle Are Affected By Prolonged Run, Sydni Wilhoite Ms Jan 2019

Ankle-Knee Initial Contact Angle And Latency Period To Maximum Angle Are Affected By Prolonged Run, Sydni Wilhoite Ms

College of Graduate Studies: Theses & Dissertations

INTRODUCTION: The angle experienced at initial contact and midstance have been suggested to influence the risk of injury. Previous literature has not assessed these angles under the influence of novel footwear for a non-exhaustive prolonged run or the relationship between the angles. PURPOSE: The purpose of this study was to assess the change of lower extremity kinematic parameters and the relationship between kinematic parameters at initial contact and midstance with prolonged running under the influence of different types of footwear. METHODS: The participants included 12 experienced, recreational runners (6 male; 6 female; 24.8 ± 8.4 years; 70.5 ± 9.3 kg; …


The Effect Of Loading Rate On Annulus Fibrosus Strength Following Endplate Fracture, John Mcmorran Jan 2019

The Effect Of Loading Rate On Annulus Fibrosus Strength Following Endplate Fracture, John Mcmorran

Theses and Dissertations (Comprehensive)

Low back pain is the most prevalent cause of chronic pain for North Americans, and its correlation with endplate damage, and deficient mechanical properties in the annulus fibrosus (AF) makes this injury particularly concerning. To date, biomechanical alterations in the AF following endplate fracture have not been well described. Owing to the AF’s collagenous composition, and the intrinsic biomechanics of intervertebral discs (IVDs) during compression, it was hypothesized that the mechanical properties of AF specimens would show rate-dependent alterations in their tensile and adhesive strengths following endplate fracture. The purpose of the present study was to quantify the mechanical properties …
