The Effects Of Asymmetric Cervical Muscle Fatigue On Cervical Proprioception, Stepping, And Standing Postural Sway, Maryam Homafar

LSU Master's Theses

Background: The cervical spine contributes critically to proprioception and postural control through its dense mechanoreceptor population. The acute effects of asymmetrical cervical muscle fatigue on proprioception, gait, and balance remain understudied, especially considering its widespread occurrence in multiple populations.

Objective: To investigate the acute effects of asymmetrical cervical muscle fatigue on cervical proprioception, stepping ability, and standing postural sway in healthy young adults.

Methods: Eighteen of 25 healthy participants, who met the inclusion criterion of baseline cervical joint position error (CJPE) below 4.5° for left and right rotational directions, completed pre-fatigue and post-fatigue assessments with eyes closed, including CJPE test, …

Qualitative Versus Quantitative Analysis Of Entheses: Using An Ordinal Scale And 3d Scanned Metrics To Understand Entheseal Differences In The Charity Hospital Cemetery (16or108), Gillian Stewart

LSU Master's Theses

Using a sample from New Orleans’ Charity Hospital Cemetery (16OR108), an analysis between ordinal scores and digital quantitative analysis (DQA) measurements of the entheses (muscle attachment sites) was performed. The skeletal elements (n = 235) examined were the humerus, radius, femur, and tibia. The entheses were 3D scanned using an Artec Space Spider scanner and processed with the Artec Studio Professional© v.2018 and Geomagic Wrap® v.2021 software. Entheses were analyzed by: left and right sides, male and female, and distribution of scores across elements. The analyses yielded significant differences between proliferative and erosive score distribution. Scores between elements exhibited variation. …

The Hoof Inside Out: A Comprehensive Investigation About The Shoe Configuration Effects On The Behavior Of The Equine Hoof, Rita Aoun

LSU Doctoral Dissertations

The equine hoof is a unique organ in biology that has intricate elastic properties. From simple protection to therapeutic and corrective measures, horseshoes are widely used in the equine industry. Various types of shoeing have been designed and used based on their unique targeted functions following hoof care. Shoes can modify the gait of the horse, affect the alignment of the distal joints, and alter stress and strains on specific hoof regions. The objective of this dissertation is to provide an overview of the available research on the existing methodology and literature on the effects of shoeing on equine gait …

Biomechanical Comparisons Of Metacarpophalangeal Joint Arthrodesis Techniques In The Horse, Lawrence Ivan M. Kadic

LSU Master's Theses

INTRODUCTION - Break down injuries resulting in the disruption of the suspensory apparatus, or the development of moderate to severe osteoarthritis of the metacarpophalangeal (MCP) and/or metatarsophalangeal (MTP) joint, are well documented reasons to perform a surgical arthrodesis in horses. The objective of this thesis was to compare the biomechanical characteristics of different arthrodesis techniques for the equine MCP joint.

MATERIALS AND METHODS - The first cadaveric study evaluated the biomechanical properties of two constructs with 5.5 mm broad 10-hole LCP alone or in combination with a 2.0 mm stainless-steel cable under cyclic fatigue testing and single cycle to failure …

Assessing The Validity Of The Estimation Of Population Affinity From The Maxillary Hard Palate: An Empirical Approach Using A Modern Forensic Sample, Christopher M. Goden

LSU Master's Theses

In response to Beathard and DiGangi’s (2020) call to action for empirical assessment of population affinity estimation methodology, this study investigates the validity of maxillary palate shape as an indicator of ancestral population affinity for human skeletal remains through the use of Elliptical Fourier Analysis (EFA) and Linear Discriminant Function Analysis (DFA). Further, this study also places emphasis on the expressed variation of palate shape within and between population groups exemplified by Principal Component Analysis (PCA) of EFA data.

Computed tomography scans of 180 individuals of Black, White, and Hispanic population affinities were obtained from the New Mexico Decedent Imaging …
