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 …

Skeletal Muscle Mitochondrial Biogenesis In Response To Exercise And Cold Exposure, Camille Larson

UNO Student Research and Creative Activity Fair

BACKGROUND: Aerobic exercise triggers mitochondrial biogenesis, the generation of new mitochondria, by ATP depletion and subsequent activation of the AMPK signaling pathway. This leads to enhanced expression of PGC-1α, a positive regulator of respiration, mitochondrial biogenesis, and adaptive thermogenesis. Previous research from our lab has shown that exercise followed by cold recovery enhances the transcription of genes associated with mitochondrial growth and division, however the recovery period was necessary for this response. Perhaps exercising in a colder external environment would induce a greater thermoregulatory response and gradient between ambient skin and core temperature that may lead to altered mitochondrial …

Introduction

Upper Limb Reduction Deficiency (ULD) is a congenital disability that affects the upper limb, which the Center for Disease Control and Prevention estimates that nearly 1,500 babies are born with ULD in the United States yearly ^1,2. Prior research has focused on functional treatment of the upper limbs but has lacked observance of the effects that prosthetics and limb loss incur to the trunk. Therefore, the purpose of this study is to examine the acute effects …

Isolating Aspects Of Gait Through The Use Of Pacing Signals: A Pilot Study, Joel Sommerfeld

UNO Student Research and Creative Activity Fair

A number of recent studies have shown that the temporal structure of pacing signals greatly influences the gait dynamics observed when coordinating with those signals. Typically, those studies have focused on autocorrelation structure (ACF). The current study builds on that work by addressing how the probability distribution (PDF) of pacing signals contributes to the process of synchronization. Results show that people use both of those sources of information when coordinating the timing of the lower limbs with an external pacing signal.
