Rehabilitating Asymmetric Gait Using Asymmetry, Tyagi Ramakrishnan Nov 2017

Rehabilitating Asymmetric Gait Using Asymmetry, Tyagi Ramakrishnan

Graduate Theses and Dissertations

Human gait is a complex process that involves the coordination of the central nervous and muscular systems. A disruption to the either system results in the impairment of a person’s ability to walk. Impairments can be caused by neurological disorders such as stroke and physical conditions like amputation. There is not a standardized method to quantitatively assess the gait asymmetry of affected subjects. The purpose of this research is to understand the fundamental aspects of asymmetrical effects on the human body and improve rehabilitation techniques and devices. This research takes an interdisciplinary approach to address the limitations with current ...

Functional Trade-Offs In Feeding Performance In Salamanders Of The Family Salamandridae, Charlotte M. Stinson Jun 2017

Functional Trade-Offs In Feeding Performance In Salamanders Of The Family Salamandridae, Charlotte M. Stinson

Graduate Theses and Dissertations

Performance is an organism’s ability to accomplish a particular task or behavior, and morphology can have a major impact on the performance of an organism. Salamanders are ecologically diverse and can feed using a variety of behaviors depending on the environment in which feeding occurs. Feeding is accomplished through the use of the hyobranchial apparatus, which lies along the oropharynx, and this structure can have competing roles; in aquatic environments the apparatus is used for suction feeding and works to depress the floor of the mouth, but during terrestrial feeding this structure projects the tongue forward out of the ...


The Interaction Of Scale And Temperature In Elastically Powered Movements, Jeffrey P. Olberding Jun 2017

The Interaction Of Scale And Temperature In Elastically Powered Movements, Jeffrey P. Olberding

Graduate Theses and Dissertations

For many animals, rapid movements place high power demands on underlying muscles. Storage of muscle energy in elastic structures and the subsequent rapid release of that energy can effectively amplify muscle power. Elastic recoil can also confer thermal robustness to performance in behaviors occurring at variable temperatures. Muscle contractile performance tends to decrease at lower temperatures, but elastic recoil is less affected by temperature. Here I examine the impacts of temperature and scale in systems using elastic recoil and I explore possible interactive effects on movement performance.

I explored the role that muscle contractile properties play in the differences in ...


The Development Of A Platform Interface With The Use Of Virtual Reality To Enhance Upper-Extremity Prosthetic Training And Rehabilitation, Ashley D. Knight Jun 2017

The Development Of A Platform Interface With The Use Of Virtual Reality To Enhance Upper-Extremity Prosthetic Training And Rehabilitation, Ashley D. Knight

Graduate Theses and Dissertations

This dissertation focuses on the investigation and development of an effective prosthetic training and rehabilitation platform with the use of virtual reality to facilitate an effective process to return amputees to the highest level of independence and functioning possible.

It has been reported that approximately 10 million people live with a limb loss worldwide, with around 30% being an upper-extremity amputee. The sudden loss of a hand or arm causes the loss of fine, coordinated movements, reduced joint range of motion (ROM), proprioceptive feedback and aesthetic appearance, all which can be improved with the use of a prosthesis and proper ...


Tiered Vs. Traditional Daily Undulating Periodization For Improving Powerlifting Performance In Trained Males, Andres Vargas Mar 2017

Tiered Vs. Traditional Daily Undulating Periodization For Improving Powerlifting Performance In Trained Males, Andres Vargas

Graduate Theses and Dissertations

Daily undulating periodization represents an increasingly popular trend in exercise science with which a traditional model has been established. Tiered daily undulating periodization pairs the DUP approach with a tiered training system which allows volume and intensity to be more evenly distributed throughout a given graining cycle. The concept of tiered daily undulating periodization is a novel form of periodization and has not been investigated. As such, a comparison of traditional and tiered daily undulating periodization has yet to be examined. Therefore, the purpose of this study was to compare the effects of traditional and tiered daily undulating periodization models ...

Bone Strain Change As A Result Of A Long Distance Run Modeled On A Finite Element Tibia, Jenna Kirstin Burnett Jan 2017

Bone Strain Change As A Result Of A Long Distance Run Modeled On A Finite Element Tibia, Jenna Kirstin Burnett

Graduate Theses and Dissertations

Stress injuries typically develop as a result of overuse and lack of recovery. However, despite a 7-year stress fracture incidence rate of approximately 40%, in vivo bone stresses and strains do not approach levels of ultimate strength. Therefore, there must be outside factors such as muscle fatigue which lead to increased strain and injury risks. PURPOSE: Muscle fatigue during a long distance run may lead to increased bone strain in the tibia, and result in increased injury risk. METHODS: Sixteen runners did a graded treadmill test to determine max heart rate and VO2,max, which were then used to set ...


Message Framing And Physical Activity: One Size Fits All Versus A Tailored Approach, Konstantinos Mantis Jan 2017

Message Framing And Physical Activity: One Size Fits All Versus A Tailored Approach, Konstantinos Mantis

Graduate Theses and Dissertations

Message framing (i.e., emphasis on gains or losses) is a communication strategy that has been used to promote physical activity (PA). Previous research has led to inconsistent results regarding the persuasive effect of gains and losses. The purpose of this dissertation was to explore whether a fit between message content and individuals’ motivational orientation improves the effectiveness of messages. Undergraduate students participated in studies via the Department of Psychology SONA system. Study 1 (n = 441) tested whether a fit between Frame (gains, losses), Regulatory Focus (promoters, preventers), and Message Valence (positive, negative, mixed) improves the persuasiveness of PA messages ...

Modulating Visuomotor Adaptation In Young Healthy Adults: Effects Of Reward And Punishment, Yanlong Song Jan 2017

Modulating Visuomotor Adaptation In Young Healthy Adults: Effects Of Reward And Punishment, Yanlong Song

Graduate Theses and Dissertations

Recent human motor adaptation/learning studies revealed that punishment accelerates acquisition of motor memory while reward enhances consolidation of motor memory. This study tested the robustness and a possible cause for this potential dissociation. During learning to adapt to an abrupt visual rotation in moving to a visual target, young healthy participants were provided with performance-based monetary reward or punishment. By manipulating the probability of reward or punishment distribution and controlling visual feedback of the cursor while moving to a target, the present study demonstrated that punishment induced faster adaptation than reward in both continuous and non-continuous visual feedback contexts ...
