Emergency Cardiac Care In Athletic Training Education, Erica M. Filep

Masters Theses, 2010-2019

In the field of athletic training, preventing sudden cardiac arrest (SCA) has become a vital component of undergraduate athletic training students’ education. Specifically, SCA is the “leading cause of death in young athletes due to a structural cardiac abnormality” (Casa et. al, 2012, p. 15). Numerous studies about sudden death in athletics have been conducted but there is a gap in educational literature. Teaching students how to respond to catastrophic injury or illness is still an area that needs to be expanded upon. Educational competencies and standards have rapidly evolved with each edition of the National Athletic Trainers’ Association (NATA) …

Prevalence Of Neurocognitive Test Failure Following Exertion In Athletes Recovering From Concussion, Caitlin Laura Zaring

Health, Human Performance and Recreation Undergraduate Honors Theses

The current return-to-play (RTP) protocol in place for an athlete recovering from a concussion is based on the subjective measure of self-report rather than more objective tools such as computerized neurocognitive testing. Because of this, it is possible that athletes downplay or lie about symptoms they are experiencing in order to expedite the RTP process. The purpose of the current study was to examine the frequency of post-exertional neurocognitive test failure in a sample of high school athletes recovering from concussion that underwent a standardized exertional RTP protocol. This research project used a de-identified medical records review of neurocognitive data …

2-Dimension Analysis Of Frontal Plane Projection Angle In Female Soccer Athletes, Kylee M. Tuchfarber

Undergraduate Distinction Papers

Research has found a variety of mechanisms for ACL injuries. One mechanism that has been found is a decreased valgus control at the knee. One study found that that “the decreased active and passive controls of knee alignments may destabilize the knee and are purported to be measures related to increased risk of ACL injury in female athletes, as they mature” (Myer, Ford, Khoury, Succop, & Hewett, 2011, 248). The age of the subjects (12-16) is important because maturation may be a contributing cause of knee abduction moments (KAM). Three-dimensionalanalysis has been said to be the “gold standard” when analyzing …

Neurocognitive Patterns, Symptom Clusters, And Premorbid Factors That Predict Protracted Recovery From Concussion In Females, Sarah Pulaski

PCOM Psychology Dissertations

Concussion is an increasingly diagnosed injury that affects individuals of all ages. Although the underlying cause is unknown, research has demonstrated that females who sustain a concussion experience longer recoveries. Existing research has documented a relationship between age, gender, post-concussive headache and mental health conditions, and recovery; however, limited research has investigated the relationship between premorbid clinical variables and recovery. Research on post-injury neurocognitive declines and recovery has also demonstrated varied findings. Moreover, dizziness has been identified as significantly predictive of prolonged recovery, but no studies have investigated the effect of premorbid headache conditions on the development of dizziness.

Designing A Mechanical Linkage Capable Of Decreasing Force Transfer From The Facemask To The Protective Helmet When Loading Occurs, Levi Hansen

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction

Sports that involve extensive personal contact have a high incidence of injury. The introduction of regulations mandating the use of personal protective equipment in these sports is the most common injury control strategy (Marshall et al., 2002). Negligible attention has been paid to the mechanical linkage between the facemask and helmet as a means of reducing force transfer from the facemask, through the helmet, and to the head and or neck of the athlete.

Methods

A novel prototype mechanical linkage of reasonable simplicity that provides 360° of freedom in motion capable of decreasing force transfer from the facemask to …

Insulin Resistance And Muscle Insulin Receptor Substrate-1 Serine Hyperphosphorylation, Charles A. Stuart, Mary E. A. Howell, Brian M. Cartwright, Melanie P. Mccurry, Michelle L. Lee, Michael W. Ramsey, Michael H. Stone

ETSU Faculty Works

Insulin resistance in metabolic syndrome subjects is profound in spite of muscle insulin receptor and insulin-responsive glucose transporter (GLUT4) expression being nearly normal. Insulin receptor tyrosine kinase phosphorylation of insulin receptor substrate-1 (IRS-1) at Tyr896 is a necessary step in insulin stimulation of translocation of GLUT4 to the cell surface. Serine phosphorylation of IRS-1 by some kinases diminishes insulin action in mice. We evaluated the phosphorylation status of muscle IRS-1 in 33 subjects with the metabolic syndrome and seventeen lean controls. Each underwent euglycemic insulin clamps and a thigh muscle biopsy before and after 8 weeks of either strength or …

Sports Related Traumatic Brain Injuries, Ky Parrott

Nursing Student Class Projects (Formerly MSN)

Traumatic Brain Injuries (TBI) are the leading cause of long-term disability and injury death in the United States of America (Dash, Oh, Santiago, & Wade, 2012, p. 108). It is estimated that approximately 75% of all TBI’s are sports related. Recently, sports related TBI’s have received increased awareness due to the $765 million settlement between 18,000 retired football players who suffer from long-term concussive injuries and the National Football Association (NFL) (Mason, 2013, p. 267). Education regarding the pathophysiology of TBI’s is beneficial to understanding what changes the brain is enduring and why it is important to protect the brain, …

Refeeding Syndrome In A Young Girl With Anorexia Nervosa., Om Parkash, Adil Ayub, Shahab Abid

Department of Medicine

We report the case of a 20-year-old anorexic girl (BMI=12.9), who was misdiagnosed the first time and developed severe electrolyte imbalances due to lack of awareness about refeeding syndrome. Few cases of RS have been reported in literature and protocols have been suggested for prevention and management of this syndrome, including the awareness of circumstances in which it is most likely to develop, refeeding slowly and building-up micronutrient content over several days. Improved awareness and understanding of refeeding syndrome along with a well-coordinated plan are vital in delivering safe and effective nutritional rehabilitation. We suggest a slow and gradual increase …

Interleukin-1 Receptor Antagonist Modulates Inflammation And Scarring After Ligament Injury, Connie S. Chamberlain, Ellen M. Leiferman, Kayt E. Frisch, Sarah E. Duenwald-Kuehl, Stacey L. Brickson, William L. Murphy, Georffrey S. Baer, Ray Vanderby

Faculty Publications - Biomedical, Mechanical, and Civil Engineering

Ligaments have limited regenerative potential and as a consequence, repair is protracted and results in a mechanically inferior tissue more scar-like than native ligament. We previously reported that a single injection of interleukin-1 receptor antagonist (IL-1Ra) delivered at the time of injury, decreased the number of M2 macrophage-associated inflammatory cytokines. Based on these results, we hypothesized that IL-1Ra administered after injury and closer to peak inflammation (as would occur clinically), would more effectively decrease inflammation and thereby improve healing. Since IL-1Ra has a short half-life, we also investigated the effect of multiple injections. The objective of this study was to …

The Influence Of Partial And Full Thickness Tears On Infraspinatus Tendon Strain Patterns, Kayt E. Frisch, David Marcu, Geoffrey S. Baer, Darryl G. Thelen, Ray Vanderby

Faculty Publications - Biomedical, Mechanical, and Civil Engineering

Tears on the bursal and articular sides of the rotator cuff tendons are known to behave differently and strain is thought to play a role in this difference. This study investigates the effect of tear location on the changes in three strain measurements (grip-to-grip, insertion, and mid-substance tissue) in a sheep infraspinatus tendon model during axial loading. We introduced a 14mm wide defect near the insertion from either the articular or bursal side of the tendon to three depths (3 mm, 7mm & full) progressively. For each condition, tendons were sinusoidally stretched (4% at 0.5 Hz) while insertion and midsubstance …
