An Automated Framework For Connected Speech Evaluation Of Neurodegenerative Disease: A Case Study In Parkinson's Disease, Sai Bharadwaj Appakaya

USF Tampa Graduate Theses and Dissertations

Neurodegenerative diseases affect millions of people around the world. The progressive degeneration worsens the symptoms, heavily impacting the quality of life of the patients as well as the caregivers. Speech production is one of the physiological processes affected by neurodegenerative diseases like Alzheimer’s disease, amyotrophic lateral sclerosis (ALS) and Parkinson’s disease (PD). Speech is the most basic form of communication, and the effect of neurodegeneration degrades speech production, thereby reducing social interaction and mental well-being. PD is the second most common neurodegenerative disease affecting speech production in 90% of the diagnosed individuals. Speech analysis methods for PD in clinical methods …

The Correlation Between Ankle Proprioception And Lower Extremity Muscle Reactions In Response To Simulated Lateral Ankle Sprains, Erin M. Carroll

Theses and Dissertations

Context: Lateral ankle sprains are one of the most commonly occurring sport-related injuries. The somatosensory system is primarily responsible for monitoring the position of the joints in space during movement. This system functions by way of neurological structures that provide proprioceptive and neuromuscular input to the brain. Motor control of the lower extremity relies on proprioceptive input to the central nervous system (CNS) and local neuromuscular control of each joint to produce coordinated, global muscular responses to external events. Previous research has investigated links between proprioception and neuromuscular control in relationship to ankle inversion separately, but none have searched for …

The Influence Of Transcranial Direct Current Stimulation On Skill Acquisition In A Complex Motor Task, Nicholas Pudar, Milan Pantovic

Undergraduate Research Symposium Posters

Transcranial direct current stimulation (tDCS) applied over the motor cortex (M1) can improve performance in relatively simple motor tasks performed with the hand and arm. Only a few tDCS studies have examined complex, multi-joint tasks. The purpose of this study was to investigate the acute effects of (tDCS) on skill acquisition in a complex, multi-joint arm movement in healthy young adults. 22 right-handed adults were randomly assigned to a tDCS or SHAM group, performing the overhand throws to a target. After the baseline-test block, transcranial magnetic stimulation (TMS) was used to locate the first dorsal interosseus muscle (FDI). Motor evoked …

Examination Of Energy Needs And Female Athlete Triad Components In Competitive Cheerleaders, Allison Smith

Theses and Dissertations

Scientific research examining these factors within cheerleaders has been limited. The purpose of this study was to examine overall ED risk across cheerleading team type (All-Star, college), squad type (all-girl, coed), and by position (flyer, base, …

The Association Between Type-2 Diabetes Pathophysiology & Exercise Adherence, Sydney Raymond

Senior Honors Projects

According to the American Diabetes Association, 1 in 3 Americans will be diagnosed with diabetes. While some of these individuals will be prescribed medications as part of their treatment, most will also be advised to begin an exercise program to assist with blood glucose control. Additionally, while regular exercise is associated with lower HbA1C and decreased insulin/medication dependence, it is estimated that only about half of those diagnosed with diabetes will adhere to their exercise plans. Social, psychological, and physiological factors all play roles in affecting ones ability to adhere to an exercise regiment, and individuals with Type 2 Diabetes …

Sleep Quality And Prevalence Of Anxiety And Depression In Young Adults With Concussion History, Jessica Barrack

Theses and Dissertations

Background: Concussions are a growing public health concern, and emerging long-term health risks may negatively impact an individual’s quality of life. With concussions, there can be a multitude of signs and symptoms, but frequent long-term sequelae of concussions including mood disturbances (e.g. trait anxiety and depression) and sleep disturbances (e.g. difficulties initiating and maintaining sleep) are given less attention. Few clinicians address mood and sleep disturbances in their concussion assessment and management plan, potentially placing individuals at risk for prolonged disturbances beyond recovery. Purpose: To examine the relationship between sleep disturbances (sleep quality) and mood disturbances (trait anxiety and depression) …

Analyses Of Countermovement Jump Performance In Time And Frequency Domains, Zhanxin Sha, Zhaoxian Zhou, Boyi Dai

Faculty Publications

This study aimed to analyze counter-movement jump (CMJ) performance in time and frequency domains. Fortyfour Division I American football players participated in the study. Kinetic variables were collected from both dominant and non-dominant legs using two force plates. Normalized peak power, normalized net impulse, and normalized peak force significantly correlated with jump height (r =.960, r =.998, r =.725, respectively with p < .05). The mean frequency component was significantly correlated with CMJ performance (r =.355 with p < .05). The reliability of the frequency variables was higher than the time domain variables. Frequency domain variables showed weaker correlations with jump height compared with time domain variables. Frequency domain analysis provides frequency components, which represent the rate of energy transmission from the eccentric phase to the end of the push-off phase. Frequency component information may provide additional information for the analyses of CMJ performance for athletes.

Efficacy Of The Opensim Simulator As A Tool To Detect Changes In Gait: A Peripheral Artery Disease Model, Cody Anderson, Hafiz Rahman, Irakis Pipinos, Jason Johanning, Sara Myers

UNO Student Research and Creative Activity Fair

INTRODUCTION

Peripheral Artery Disease (PAD) is characterized by atherosclerotic plaques in the leg arteries. A common treatment for PAD is supervised exercise training [1]. However, gait is not fully restored following supervised exercise training (SET). Musculoskeletal simulation may provide insight into how muscle activation changes following SET contributed to persistent gait alterations.

METHODS

Kinematic and kinetic data from overground walking of patients with PAD (n=12), before and after a 6-month exercise intervention, was used as input for musculoskeletal modeling (OpenSim). The subjects in our sample were subdivided based on the location of ischemic muscle pain, as reported on the San …

A Systematic Review: Long Range Correlations In Running Gait, Mr. Taylor Wilson

UNO Student Research and Creative Activity Fair

Long range correlations (LRCs) are apparent in human walking and running gait and are indicative of a healthy system. A systematic review (SR) was completed to determine the typical LRC patterns in running. 20 articles were included in the SR. LRCs in running gait tend to be similar to the LRCs in walking gait, with fatigue contributing to a negative effect on the LRCs.

This SR could have implications on training guidelines for coaches and physical therapy methods to increase the LRCs in running gait for healthier functioning. More research is needed to determine how LRCs depend on running surface …

Nox2 Inhibition Regulates Stress Response And Mitigates Skeletal Muscle Fiber Atrophy During Simulated Microgravity, John M. Lawler, Jeffrey M. Hord, Pat Ryan, Dylan Holly, Mariana Janini Gomes, Dinah Rodriguez, Vinicius Guzzoni

Health & Human Performance Faculty Publications

Insufficient stress response and elevated oxidative stress can contribute to skeletal muscle atrophy during mechanical unloading (e.g., spaceflight and bedrest). Perturbations in heat shock proteins (e.g., HSP70), antioxidant enzymes, and sarcolemmal neuronal nitric oxidase synthase (nNOS) have been linked to unloading-induced atrophy. We recently discovered that the sarcolemmal NADPH oxidase-2 complex (Nox2) is elevated during unloading, downstream of angiotensin II receptor 1, and concomitant with atrophy. Here, we hypothesized that peptidyl inhibition of Nox2 would attenuate disruption of HSP70, MnSOD, and sarcolemmal nNOS during unloading, and thus muscle fiber atrophy. F344 rats were divided into control (CON), hindlimb unloaded (HU), …
