Finite Element Reconstruction Of Real World Aortic Injury In Near-Side Lateral Automotive Crashes With Conceptual Countermeasures, Aditya Neelakanta Belwadi

Wayne State University Dissertations

Traumatic rupture of the aorta (TRA) remains the second most common cause of death associated with motor vehicle crashes after brain injury. On an average, nearly 8,000 people die annually in the United States due to blunt injury to the aorta. It is observed that more than 80% of occupants who suffer an aortic injury die at the scene due to exsanguination into the chest. With the advent of more accurate and established human body finite element (FE) models, FE crash reconstruction methods may become a valuable tool when assessing crash scenarios and occupant injury mechanisms.

The current study is …

A Counterbalanced Cross-Over Study Of The Effects Of Visual, Auditory And No Feedback On Performance Measures In A Simulated Cardiopulmonary Resuscitation, Carolyn Cason, Cynthia Trowbridge, Susan M. Baxley, Mark D. Ricard

Kinesiology Faculty Publications & Presentations - Archive

Background: Previous research has demonstrated that trained rescuers have difficulties achieving and maintaining the correct depth and rate of chest compressions during both in and out of hospital cardiopulmonary resuscitation (CPR). Feedback on rate and depth mitigate decline in performance quality but not completely with the residual performance decline attributed to rescuer fatigue. The purpose of this study was to examine the effects of feedback (none, auditory only and visual only) on the quality of CPR and rescuer fatigue. Methods: Fifteen female volunteers performed 10 minutes of 30:2 CPR in each of three feedback conditions: none, auditory only, and visual …

The Effects Of A 15 Week Exercise Intervention On Fitness And Postural Control In Older Adults, Forest Melton

Kinesiology Theses - Archive

Falls are the leading cause of nonfatal injuries in older adults, and often lead to adverse changes in confidence and lifestyle that trigger further declines in postural control. Decreased fitness is associated with poor performance on postural control assessments, especially those that increase task difficulty. The purpose of this study was to analyze the impact of a traditional Group Fitness class and a Wii Fitness exercise program on individual's ability to maintain postural control, with an environmental distracter. 87 community dwelling seniors were randomized into 1 of 3 groups (Control, Wii Fitness, Group Fitness). Interventions were delivered 3 times per …

The Relationships Between Optimism And Pessimism And Burnout In Youth Soccer Players, Brandy A. Rentz

College of Graduate Studies: Theses & Dissertations

Sport related burnout has become a concern for many athletes, coaches, and sport psychologists. Although burnout in sport is receiving more attention, the research still remains relatively limited (Capel, 1986; Dale & Weinberg, 1990; Fender, 1989; Gould, Udry, Tuffey, & Loehr, 1996). Dale and Weinberg (1990) indicated a need for future research concerning the identification of characteristics that may predispose athletes to burnout. No past research was found that investigated the relationship between optimism/pessimism and sport burnout. The primary purpose of this investigation was to examine the relationships between optimism and pessimism with burnout. A secondary purpose was to determine …

The controllers of this relationship are unclear, but appear to involve biomechanical and biochemical influences on the vascular wall. Purpose: The purpose of this dissertation was twofold: (1) to explore the relationship between vascular health and physical function in three populations (elderly, young and chronic heart failure patients); and (2) to determine the modifying role of physical activity, inactivity and exercise training on controllers of this relationship. Methods: Four projects were designed to address 3 key issues in exercise vascular biology, including the influence of the pattern of blood …

Examining The Perceptions Of Teachers' Efficacy In Handling Student Misbehavior (Tehsm) In Classroom And Physical Education Settings, Costas Nicou Tsouloupas

LSU Doctoral Dissertations

Research has found dealing with student misbehavior as the most prominent source associated with teachers’ negative behavioral outcomes at work. One approach for understanding teachers’ behavioral responses to student misbehavior is through the efficacy beliefs of teachers. This line of inquiry has lead to the advancement of the concept of teacher efficacy in handling student misbehavior or TEHSM. TEHSM was found to significantly and negatively mediate the relationship between teachers’ perception of student misbehavior, emotional exhaustion, and turnover intentions respectively. To date, limited information is available regarding the makeup of TEHSM which gives emphasis to the significance of this dissertation. …

The Association Between Different Clinical Methods For Evaluating Lower Extremity Muscular Function, Roger Olen Kollock Jr.

Human Movement Studies & Special Education Theses & Dissertations

Insufficient muscular strength at the hip and thigh may increase an athlete's susceptibility to lower extremity injuries. In an attempt to reduce this risk, researchers have proposed lower limb strength testing within preparticipation physical examinations (PPE) and return-to-play (RTP) evaluations. However, because of cost, mobility, and or set-up time, some methods are not feasible in certain settings. Since methodological approaches between methods can vary, having different contraction modes and testing parameters, substitution of one method for another may not be valid. Therefore, the purpose of this study is three-fold: a) to determine the association between isometric and isokinetic contraction modes …

A Multi-Species Analysis Of Biomechanical Responses Of The Head To A Shock Wave, Richard Bolander

Wayne State University Dissertations

Shock wave induced brain injury remains a field of research that has great consequences for the rehabilitation of soldiers and civilians that are exposed to an explosion. As such, for the research to be successful in developing strategies to mitigate the effects of these injuries, appropriate research methods need to be developed. Animal models are currently employed to understand the brain's response to a shock wave exposure. Unfortunately no criteria have been established that indicates in what way the mechanical inputs that the cells in an animal's brain are subjected to are similar to a human. The purpose of this …

Computational Simulation Of Skull Fracture Patterns In Pediatric Subjects Using A Porcine Model, Christina Devito Wagner

Wayne State University Dissertations

In cases of suspected child abuse with skeletal trauma, it is often the role of the injury biomechanist, forensic pathologist, clinical radiologist, and forensic anthropologist to determine the mechanism of injury when the child victims cannot speak for themselves. This is a challenging task, especially for the head, as comprehensive biomechanical data on skull fracture in infants and children do not currently exist, and frequently the determination regarding cause of injury is based on anecdotal evidence from the medical literature and unsubstantiated eyewitness accounts. The current process may result in unreliable autopsy interpretation and miscarriages of justice due to a …

Psychosocial Aspects Of Physical Activity And Fitness In Special-Population, Minority Middle School Children, Jeffrey J. Martin, Nate Mccaughtry, Anne S. Murphy, Sara Flory, Kimberlydawn Wisdom

Kinesiology, Health and Sport Studies

Special-population research predicting physical activity (PA) and fitness with minority middle school children from at-risk environments is rare. Hence, the purpose of our investigation was to evaluate the ability of important social cognitive and environment-based measures to predict PA and fitness with children with developmental delay, cognitive, and emotional impairments. Children (N = 89, ages 11-15) completed questionnaires assessing social cognitive and environment-based constructs, self report PA, and completed fitness testing. Correlational results supported some hypotheses. The descriptive and correlational results also indicated commonalities with similar research on non special-population minority middle school children from at-risk environments.

Walking Abnormalities Are Associated With Copd: An Investigation Of The Nhanes Iii Dataset, Jenna M. Yentes, Harlan Sayles, Jane Meza, David M. Mannino, Stephen I. Rennard, Nikolaos Stergiou

Journal Articles

Research on the peripheral effects of COPD has focused on physiological and structural changes. However, different from muscular weakness or decreased physical activity, mechanical abnormalities of the muscular system, e.g. walking, have yet to be investigated. Our purpose was to utilize the National Health and Nutritional Examination Survey (NHANES) dataset to determine whether walking abnormalities are associated with COPD severity. To determine if walking abnormalities were independently associated with COPD severity, our analysis aimed to investigate the association of physical activity levels with COPD severity and with walking abnormalities. The NHANES III dataset that contains data for 31,000 persons that …

Fatigue, reduced quality of life (QOL), and lower physical activity levels are commonly reported in patients with multiple sclerosis (MS). This study evaluated the effects of elliptical exercise on fatigue and QOL reports in patients with MS. Patients with MS (n = 26) completed the Fatigue Severity Scale (FSS), the Modified Fatigue Impact Scale (MFIS), and the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) before and after completing 15 elliptical exercise training sessions. Changes in fatigue and QOL were assessed based on any changes in the fatigue and SF-36 questionnaires, and correlations between changes in each of the …

The Role Of Motivation And Physical Activity In A Weight Loss Program, Ellen Kane Stevens

LSU Master's Theses

Every year thousands of overweight and obese people in the United States join weight loss programs such as Weight Watchers in an effort to become healthier and feel more attractive. Weight Watchers has increased its program focus on physical activity as a critical part of weight loss. Initiating a consistent physical activity routine, however, is generally one of the last behavior changes made by program members, despite its proven role in weight loss maintenance. Using self-determination theory as a framework, the purpose of this study was to examine how perceptions of fulfillment of three psychological needs (i.e. competence, autonomy, and …
