Therapeutic Neuroscience Education For Patients With Chronic Low Back Pain And Its Effect On Activity Level, Pain Perception, And Function, Stephen Burton, Amber Domingo, Ryan Spencer

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background: Chronic low back pain (CLBP) is a significant cause of disability and inactivity in the United States. Patients with chronic pain are often symptomatic even in the absence of tissue damage. This is a major reason patients need to be educated about their pain. Cognitions such as fear, anxiety and faulty beliefs may impact the pain experiences and changing cognitions are important in changing pain behavior. If patients understand that the pain they are experiencing may not be a true indication of the health of their tissues, they may experience less fear of their pain, and may be able …

Effects Of Footstrike Pattern On Low Back Posture, Shock Attenuation, And Comfort During Running, Traci L. Delgado, Emilia Kubera-Shelton, Robert R. Robb

UNLV Theses, Dissertations, Professional Papers, and Capstones

Purpose: Barefoot running (BF) is popular in the running community. Biomechanical changes occur with BF, especially when initial contact changes from rearfoot strike (RFS) to forefoot strike (FFS). In addition, changes in lumbar spine range of motion (ROM), particularly involving lumbar lordosis, have been associated with increased low back pain (LBP). However it is not known how changing from RFS to FFS affects lumbar lordosis or LBP. Thus, the purpose of this study was to determine if a change from RFS to FFS would change lumbar lordosis, and/or decrease shock attenuation, and/or change comfort levels in healthy recreational/experienced runners.

Concurrent Neurological And Behavioral Assessment Of Number Line Estimation Performance In Children And Adults, Joseph Michael Baker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Understanding the brain’s response to common math-learning activities may help improve math education. For example, by imaging the brains of typically developing children and adults throughout a number line estimation task, it is possible to establish a baseline of what “typical” brains do in such situations. Thus, comparisons may be made to determine the degree to which brain functioning differs between typical and atypical math learners. Moreover, by identifying methods that may increase the brain’s response to real-world math activities, it may be possible to improve the math learning process for typical and atypical learners alike.

Brain imaging devices such …

Comparison Of The Pervasive Developmental Disorders Screening Test And Modified Checklist For Autism In Toddlers: Which Is The Better Predictor Of Autism In Toddlers?, Vanessa Marie Fessenden

UNLV Theses, Dissertations, Professional Papers, and Capstones

Early intervention for children with autism spectrum disorders (ASD) has significant impact on children and families. Early intervention optimizes long-term diagnosis for children with ASD. Unfortunately, many children with ASD are not diagnosed until after age three and often receive services from a local school district rather than through early intervention services. However, many of the symptoms of ASD can be hard to identify because symptoms during infancy may be more difficult to detect or may present differently than manifestations of the symptoms at older ages. Despite the difficulty in identifying symptoms of ASD in young children, there are certain …

The Effects Of Chronic Calcium Dysregulation On Behavioral And Pathological Features Of Alzheimer's Disease, Jonathan Sabbagh

UNLV Theses, Dissertations, Professional Papers, and Capstones

Alzheimer's disease (AD) is a progressive neurodegenerative disorder whose etiology is unknown. Recent studies have implicated alterations in calcium homeostasis as a pathogenic contributor to AD. Calcium dysregulation has been observed in aged and AD brains, an event which could potentially facilitate the development of multiple pathologies observed in AD. Specifically, disrupting intracellular calcium levels in vitro has been demonstrated to increase amyloid-beta (Aβ) production, tau phosphorylation, and neuronal loss. However, there is a paucity of data on the behavioral and biochemical consequences of chronic in vivo perturbation of calcium homeostasis. In a series of experiments designed to evaluate the …

Perceptions Of Police Responses To Domestic Violence, Kelly Rae Stout

UNLV Theses, Dissertations, Professional Papers, and Capstones

Domestic violence, also known as, intimate partner violence (IPV), has become an epidemic in the United States. According to the Center for Disease Control and prevention (CDC), about 24 women and men are victimized by an intimate partner each minute, equaling about 12 million victims every year (2012b). In recent years, the public has become more aware of IPV situations. An increase in public service announcements has helped to inform the public and has brought these dangerous situations out from behind closed doors. In the age of technology, information is more easily distributed and exchanged which has also increased public …

School Nurses' Recognition, Attitudes, And Educational Needs Regarding The Care Of Children With School Refusal Behavior, Heather Strasser

UNLV Theses, Dissertations, Professional Papers, and Capstones

School refusal behavior can prevent a child from attending school or staying in class for a full day of instruction. School nurses are often one of the first professionals in the school with the opportunity to interact with these children, recognize school refusal behavior and its debilitating impact, and positively intervene to assist these children to stay in school. Few studies have examined school nurse recognition and attitudes regarding school refusal behavior. The purpose of this study was to assess school nurses' recognition of school refusal behavior, their attitudes regarding the nursing care of children with school refusal behavior, and …

A Comparison Of Nursing Service Demand In Title 1 Schools And Non-Title 1 Schools, Karen Ray Stratford

UNLV Theses, Dissertations, Professional Papers, and Capstones

Children from low-income families are known to struggle academically, but lack of health services may also impact their education. School nurses must identify and manage health problems in the school-age child to improve academic success. Unfortunately, the school nurse-to-student ratio may limit the amount of time nurses can give to the recognition of health problems and appropriate follow-up. The Elementary and Secondary Education Act of 1965 provides Title 1 funding to schools whose enrollment includes at least 40% of low-income families. These federal funds are intended to be used to bridge the achievement gap between low-income students and other students. …

Oxidative Stress For An Acute Bout Of Bikram Yoga In Healthy, Trained Adults, Kimberly Anne Trocio

UNLV Theses, Dissertations, Professional Papers, and Capstones

BACKGROUND:Generation of free radicals resulting in oxidative damage has been linked to cellular damage, aging, and human disease. Many studies have reported that physical exercise can contribute to oxidative stress. Further, exercise in a hyperthermic environment can promote additional oxidative stress. It is important to consider that practices in yoga may be beneficial in reducing oxidative stress according to some studies. The compound effects of exercise and hyperthermic exposure are experienced in the practice of Bikram yoga, the original "hot" yoga. Because Bikram yoga and other hot exercise classes are an increasingly growing fitness trend, it is necessary to investigate …

Genetic Analysis Of The Promoter Region Of The Serotonin Receptor 5ht2b And Its Contribution To Pulmonary Hypertension Syndrome In Broiler-Type Chickens, Khaloud Awada Alzahrani

Graduate Theses and Dissertations

Pulmonary Arterial Hypertension (PAH) is a sever disorder characterized by high pulmonary artery pressure and pulmonary vascular resistance along with specific histological changes. Idiopathic PAH is a human disease of unknown origin that showed common characteristics to PHS/ascites in chicken. PHS/ascites is a condition found in broilers causing right ventricular hypertrophy, valvular insufficiency, increased venous pressure, variable liver changes, accumulation of fluids in the abdominal cavity, and finally lung and heart failure. Currently, there is no acceptable animal model for human PAH. Our group has been validating the chicken as the medical animal model for human PAH, thus we have …

Nursing Students' Attitudes Toward Science In The Nursing Curricula, Jill Deanne Maroo

Dissertations

The nursing profession combines the art of caregiving with scientific concepts. Nursing students need to learn science in order to start in a nursing program. However, previous research showed that students left the nursing program, stating it included too much science (Andrew et al., 2008). Research has shown a correlation between students’ attitudes and their performance in a subject (Osborne, Simon, & Collins, 2003). However, little research exists on the overall attitude of nursing students toward science. At the time of my study there existed no large scale quantitative study on my topic. The purpose of my study was to …
