Effects Of Bimodal Transcranial Direct Current Stimulation On Modulation Of Spinal Circuitry In People With Chronic Post-Stroke Hemiparesis, John Patrick Gan, Rafael Cabrera, Lana Laudermilch, Benjamin Wolkenhauer

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background: Stroke can lead to gait abnormalities such as foot drop. Foot drop can result from decreased corticospinal tract input to the ankle dorsiflexors and/or from exaggerated stretch reflexes on the soleus due to reduced reciprocal inhibition from spinal reflex pathways. Transcranial direct current stimulation (tDCS) attempts to modulate corticospinal tract input and spinal reflex pathways by delivering electrical signals to parts of the brain. The degree of neuromodulation from tDCS can be measured through the Hoffman Reflex (H-reflex)—a tool used to estimate alpha motor neuron excitability which is increased in individuals post-stroke. Purpose: The primary purpose of this study …

Inter And Intra-Rater Reliability Of Dance Screening Tool, Kathleen Stone, Braden Waters

UNLV Theses, Dissertations, Professional Papers, and Capstones

Previous literature has indicated that injury rates of ballet and modern dancers are among the highest of any physical activity. These injuries can be detrimental to the athlete and can also result in financial burden for dance companies due to time loss related to injuries. Preventative intervention aimed at those who are most at risk for injury can be effective at reducing the cost associated with lost time due to injury. An effective approach to identifying those most at risk for dance related injuries is to administer a functional movement screen. One such movement screen is the ballet-based Dance Technique …

This paper describes various methods for recruiting clinician involvement to improve the sustainability of a student led pro bono clinic, as well as how the students advocated for pro bono services in the state of Nevada …

Is Decreased Trunk Flexion Angle A Contributing Factor To Patellofemoral Joint Loading In Runners With Patellofemoral Pain?, Christine Duvall, Zachary Clark, Tavin Fox, Caitlin Howden

UNLV Theses, Dissertations, Professional Papers, and Capstones

Purpose/Hypothesis: Reduced trunk flexion during running is theorized to be a contributing factor of elevated patellofemoral joint (PFJ) stress in runners with patellofemoral pain (PFP); thus, the primary purpose of this research study was to determine if runners with PFP would exhibit differences in PFJ stress and trunk flexion angle during running as compared to pain-free runners across three speeds. We hypothesized that runners with PFP would exhibit higher PFJ stress and decreased trunk flexion while running compared to the pain- free runners. Number of Subjects: 7 runners with PFP and 5 similar pain-free control runners. Materials/Methods: Kinematics and kinetics …

A Vicious Cycle Of Fear Of Falling Avoidance Behavior In Parkinson’S Disease: A Path Analysis, Kameron Jacobson, Nicole Matsunami, Hannah Mccarl, Michelle Regis

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background: Postural instability (PI) in Parkinson’s disease (PD) is associated with several negative down- stream consequences. Objective: The purpose was to explore the validity of a theoretical model of these downstream consequences arranged in a vicious cycle wherein PI leads to decreased balance con!dence, which in turn leads to increased fear of falling (FOF) avoidance behavior, which in turn leads to decreased physical conditioning, which then feeds back and negatively affects PI. Methods: A path analysis of cross!sectional data from 55 participants with PD was conducted. The four con- structs in the model connected in succession were: 1. PI (principal …

Effects Of Altered Somatosensory Input On Lower Limb Mechanics Via Different Shoes And Barefoot Walking In Individuals With Chronic Post-Stroke Hemiparesis, Aaron Abraham Simon, Jynelle Marie Guerrero Arches, Megan Leigh Keohane, Wee Jin Jed Lee

UNLV Theses, Dissertations, Professional Papers, and Capstones

[Purpose/Hypothesis] Stroke is a leading cause of disability that results in various neurological deficits. Stroke can cause impaired somatosensory input, which results in decreased balance and gait speed, ultimately increasing fall risks. Therapies to increase somatosensory input have shown promise for people with stroke as well as other neurological populations. However, few studies have systematically investigated varying somatosensory input via different footwear to improve walking in people post-stroke. The purpose of this study was to investigate the effects of altering somatosensory input via different types of footwear (i.e., barefoot, self-selected shoes, and memory foam shoes) on gait kinetics and ankle …

Am-Pac Basic Mobility Inpatient Short Form (Low Function) Psychometrics/Clinimetrics, Meghan Wonderling, David Miller, Selena Soria

UNLV Theses, Dissertations, Professional Papers, and Capstones

Objective: To determine whether the Activity Measure for Post-Acute Care® Basic Mobility Inpatient Short Form (Low Function) (6-clicks LF) has increased responsiveness for patients with lower levels of physical function compared to the Activity Measure for Post-Acute Care Basic Mobility Inpatient Short Form (6-clicks). Design: Retrospective cohort study using original scores and simulated scores for assessment of internal responsiveness of the 6-clicks LF compared to the 6-clicks. Simulated 6-clicks and 6-clicks LF scores were created as a hypothetical future AM-PAC® score. Results: We found a statistically significant difference between the 6-clicks and simulated 6-clicks, t=24.8, p < 0.00 [two-tailed]. The effect size was large (d=1.2, r=0.51).There was a statistically significant difference between the 6-clicks LF and simulated 6-clicks LF, t=19.7, p < 0.00 [two-tailed]. The effect size was medium (d=0.91, r=0.41). Finally, for patients with a 6-clicks score in the bottom five-percentile (n=27), we found a statistically significant difference between the 6-clicks and 6-clicks LF, t=11.9, p < 0.00 [two-tailed]. Conclusion: Among patients scoring less than 15, the 6-clicks LF has greater internal responsiveness than the 6-clicks and thus demonstrates that the new low-level questions in the 6-clicks LF better quantify low-level patients’ functional level. Research using non-simulated data should be completed in the future to confirm these findings.

Quantifying Fear Of Falling By Utilizing Objective Body Sway And Muscle Contraction Measures, Chenfan Gui

Theses & Dissertations

Fear of falling (FOF) is a psychological condition that can lead to increased morbidity and mortality in the elder population. However, the subjective and multidimensional nature of FOF resulted in the limitations of existing FOF measurements, which could influence the quality of those studies. The present study aimed to quantify FOF by using objective center of pressure (COP) trajectories and muscle contraction of the lower extremity to compensate for those limitations. Nineteen young healthy adults (24 years ± 2.47) were recruited in the present study. Subjects were required to watch three 360-degree videos, one control video and two roller coaster …

The Effect Of Obstacle Intervals On Foot Integrated Pressure And Obstacle Negotiation Strategy, Zhuo Wang

Theses & Dissertations

When stepping over a single obstacle, despite of some spatiotemporal parameter changes, the impulse of the leading and trailing leg stays the same. This is considered an efficient obstacle avoidance strategy. However, research has shown that the strategy of multiple obstacles negotiation is different from a single obstacle crossing. Would this efficient strategy still exist during multiple obstacles negotiation? This study attempted to answer this question. Nineteen healthy young adults were recruited in this study. Each participant was required to complete 15 trials under 3 conditions: one-step, two-step, and three-step intervals. Data were collected for foot integrated pressure (FIP), walking …

Adaptation Of Human Locomotion And Unilateral Limb Loading During Different Inclination Treadmill Walking, Yuhang Zhang

Theses & Dissertations

Human locomotion is adaptive in any external environment or different terrains, which has been widely investigated. For example, people can walk at different walking speeds in each leg on a split-belt treadmill. However, human locomotor behaviors are passively adapted during the split-belt treadmill walking. Therefore, the knowledge of how humans actively adjust the flexibility of locomotion is limited by using the split-belt treadmill. To address this gap, this study investigated the flexibility of locomotion by using a 4-lb ankle weight on the dominant leg to induce the asymmetric walking pattern when walking on the inclined, declined, and level treadmill. Twenty …

Is The Walking Pattern Similar Between Slope Walking And Obstacle Negotiation?, Jiani Lu

Theses & Dissertations

Studying biomechanical characteristics of human motion sheds light on the motor control strategies in the central nervous system. Slope walking and obstacle negotiation appear to have some similarities in control strategies based on subjective observation, but these two motions have never been compared objectively in biomechanics literature. This study aimed to investigate the similarities between obstacle negotiation and slope walking in kinematics and muscle activity. The similarities were determined by the correlation of the maximum heel elevation and muscle co-activation index between obstacle negotiation and inclined treadmill walking. The strength of correlation was compared in four different pairs of conditions: …
