Its Skin Is My Skin, Bryan Page

Graduate School of Art Theses

This text examines the complexity of attempting to empathize with bodies that are vastly othered from my own. This broad yet nuanced subject crosses epistemological boundaries and complicates the dualities between both the mind and body, and between the corporeal and the virtual. My desire to better understand the conditions of another’s experience originates from a painful traumatic loss which caused me to feel isolated and incomplete. In response to this suffering, I long to emotionally connect with other beings and create artwork that attempts to bridge the qualia of individual experience.

I am interested in the capacity (or lack …

Comparative Plasma Proteomics In Muscle Atrophy Induced By Cancer Cachexia And Hindlimb Unloading, Kirsten Rene Dunlap

Graduate Theses and Dissertations

Introduction: Muscle atrophy results from a dysfunction in protein turnover that leads to loss of mass and function and occurs concurrently with multiple pathologies such as cancer and extended bed rest. Atrophy reduces overall quality of life while increasing morbidity and mortality. Currently, efficacious therapeutic interventions to treat and prevent muscle wasting in all its forms are lacking, however if conserved mechanisms can be identified between wasting conditions, this would aid in the development of multipurpose therapeutics to ameliorate this pathology. Purpose: To examine circulating factors present across atrophic pathologies. Methods: 35 male C57BL/6J mice were assigned to hindlimb unloading …

The Effects Of Injury On Running Status And Gait Biomechanics, Kristyne Wiegand

UNLV Theses, Dissertations, Professional Papers, and Capstones

Over the past several decades, endurance running has grown steadily as a popular form of physical activity. Running is easily accessible, does not require expensive equipment, and can be performed without specific skill training. Individuals who run also experience health benefits like increased cardiovascular health and reduced risk of all-cause morbidity. Despite these benefits, running is also associated with high rates of musculoskeletal injury. Although researchers have attempted to identify injury risks and mitigate the incidence of running injury, there is still no consensus as to why runners become injured. Research has also attempted to identify biomechanical movement patterns that …

Kinetic And Kinematic Characteristics Of Accentuated Eccentric Loading, John Wagle

Electronic Theses and Dissertations

The use of …

Validation Of A 5-Minute Vpc Test To Assess And Compare Cognitively Intact Individuals And Individuals With Cognitive Impairments, Spencer Smith

Graduate Theses and Dissertations

The prevalence of cognitive impairments in the older adult population is growing. Finding treatment solutions to impede a cognitive decline can possibly lead to fewer cases of mild cognitive impairment, dementia, and Alzheimer’s disease. A Visual Paired Comparison (VPC) could serve as a tool to predict, monitor, and regulate people who are susceptible to a cognitive decline. The purpose of this study was to 1) to determine the validity of the Neurotrack 5-minute VPC test with the Neurotrack 30-minute VPC test, 2) to determine the test-retest reliability of the Neurotrack 5-minute VPC test, 3) to compare Neurotrack 5-minute VPC scores …

Validity And Reliability Of A 5-Minute Web-Camera Based Eye Tracking Test To Assess Visual Memory And Cognition, Emily Bates

Graduate Theses and Dissertations

There are approximately 5.7 million Americans currently living with Alzheimer’s Disease (AD). Early detection of cognitive impairment allows for earlier treatment, potentially slowing or halting cognitive decline. A 30-min web-camera eye tracking assessment (30-min VPC) has been validated as a tool to predict AD risk. However, a shorter version would allow for greater scalability and improve user experience. The purpose of this study was to: 1) determine the validity of the 5-minute web-camera based VPC test with the 30-min test, 2) determine the test-retest reliability of the 5-min test, 3) compare the 5-minute test scores of cognitively intact adults (18-39 …

Honors College Theses

Efficient feeding accuracy could increase an organism’s survival. Although local adaptation in Trinidad guppies is common, the effects on accuracy are unknown. Guppies were wild caught in 2015 and 2017, filmed while capturing prey. Accuracy wasn’t different within samples but differed across samples, possibly due to the prey types used.

Synchronization Dynamics Modulates Stride-To-Stride Fluctuations When Walking To An Invariant But Not To A Fractal-Like Stimulus, Joao R. Vaz, Boman Groff, Douglas Rowen, Brian Knarr, Nicholas Stergiou

Journal Articles

Walking with different types of cueing/stimulus (i.e. auditory, visual) has been shown to alter gait variability, thus emerging as an innovative therapeutical tool to restore abnormal gait variability in clinical populations. However, the majority of the research in this area has focused on auditory stimuli while visual stimuli are an understudied alternative that needs more attention, particularly due to the natural dependence on vision during walking. Furthermore, the time differences between the occurrences of the walking steps and the sensory cues, also known as asynchronies, have also received minimal attention, even though the ability to synchronize with different stimuli is …

Sixteen subjects (age 18-35 yrs.; male (n=14); female (n=2)), with at least 1 year of deadlifting experience, were randomly assigned into a control and intervention group (both n=8). Both groups performed two sets of three repetitions of deadlifts at 50% and at 80% of their estimated one repetition maximum (1-RM). …

Estimation Of Arterial Wall Parameters Via Model-Based Analysis Of Noninvasively Measured Arterial Pulse Signals, Dan Wang

Mechanical & Aerospace Engineering Theses & Dissertations

This dissertation presents a model-based method for estimating arterial wall parameters from noninvasively measured arterial pulse signals via a microfluidic-based tactile sensor. The sensor entails a polydimethylsiloxane (PDMS) microstructure embedded with 5×1 transducer array built on Pyrex/Polyethylene terephthalate (PET) substrate. The arterial pulse causes a time-varying deflection on the top of the PDMS microstructure, which registers as a resistance change by the transducer at the site of the artery.

Owing to the time-harmonic nature of its radial motion, the arterial wall is modeled as a second-order dynamic system. By combining this dynamic model with a hemodynamic model of blood flow, …

The Role Of Interaction And Predictability In The Spontaneous Entrainment Of Movement., Dobromir Dotov, Valérie Cochen De Cock, Christian Geny, Petra Ihalainen, Bart Moens, Marc Leman, Benoît Brady, Simone Dalla Bella

Journal Articles

People walking side by side spontaneously synchronize their steps on some occasions but not on others, which poses a challenge to theories of perception-action based on interactive dynamic systems. How can action be spontaneously entrained by some sources of perceptual information while others are selectively ignored? The predictive processing framework suggests that saliency factors such as stimulus predictability, consistent deviation, and interactivity of the stimulus control the coupling between the motor system and perceptual information. To test this, we compared entrainment of gait cadence by two interactive auditory stimuli and two noninteractive but predictable, faster than preferred stimuli that were …

Commentary: The Use Of Case-Based Learning And Concept Mapping To Teach Students Clinical Reasoning, Jeremy R. Hawkins, Michael Reeder, Michael Olson, Amy Bronson

Journal of Sports Medicine and Allied Health Sciences: Official Journal of the Ohio Athletic Trainers Association

Introduction: Teaching students as inexperienced clinicians the process of evaluating athletic injuries and medical conditions is often challenging. Utilizing case-based learning and concept mapping as educational tools can facilitate growth in the clinical and diagnostic decision making process. Discussion: Experienced clinicians regularly employ case pattern recognition and hypothetico-deductive reasoning in clinical settings. Each type of reasoning is prone to anchoring and confirmation bias, devaluing relevant information, and framing effect if not utilized correctly. Classroom instructors and preceptors can use case-based learning and concept mapping to help students as inexperienced clinicians organize their thinking and more effectively apply their …

How Prosthetic Ankle Stiffness & Load Carriage Affect Metabolic Energy Expenditure During Walking, Erica A. Hedrick, Philippe Malcolm, Jason M. Wilken, Kota Z. Takahashi

UNO Student Research and Creative Activity Fair

The ankle structures play a key role in body support, forward propulsion and leg swing. One important property of the human ankle is its ‘quasi-stiffness’, or resistance to angular motion. The ankle joint stiffness can play a role in aiding the lower leg as its rocks over the foot. Human biological ankle stiffness changes in response to changes in the mechanical demands of walking (e.g. added load or changes in speed), using active muscle contractions. However, the role of ankle stiffness in regulating metabolic energy across walking conditions is unknown. Therefore, the purpose of this study is to determine how …

How The Foot Modulates Its Mechanics During Uphill And Downhill Walking, Jeffrey M. Patterson, Kota Z. Takahashi

UNO Student Research and Creative Activity Fair

The foot's biomechanical role in walking on sloped surfaces is currently unclear. While previous biomechanics studies have examined the hip, knee, and ankle, the foot is oversimplified as a rigid-body segment. This oversimplification overshadows its complex structure and function. In this project, we use an innovative multi-segment foot model to explore how the foot adapts its mechanics to incline and decline walking. Preliminary results have revealed that the foot is capable of adapting its mechanical work profile to both incline and decline walking. Specifically, the foot can increase its positive work output (i.e., increased energy generation) during inclined walking to …

Effect Of Dual-Task Walking On Long-Range Correlations In People With Parkinson's Disease, Shane Meltz

UNO Student Research and Creative Activity Fair

Parkinson’s Disease (PD) causes gait to be more variable and more random. Gait variability is related to disease severity, and may be a marker of fall risks. Gait in PD is attention-dependent, meaning a distraction while walking could be detrimental. The effects of dual-task walking on gait variability in PD are unclear (in particular fractal fluctuations). This study will determine if dual-task walking impacts stride-to-stride variability compared to normal walking in people with Parkinson’s Disease. We predict that dual-tasking will lead to more random stride-to-stride variability in people with PD, compared to controls. Also, within the PD group, we predict …
