Quantifying Fear Of Falling By Utilizing Objective Body Sway And Muscle Contraction Measures, Chenfan Gui
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 …
Effects Of A Dual-Task Paradigm On Tandem Gait Performance, Courtney Angela Perry
Effects Of A Dual-Task Paradigm On Tandem Gait Performance, Courtney Angela Perry
Cal Poly Humboldt theses and projects
In concussion management, a variety of cognitive and motor control tests, like the tandem gait, have been used for assessing the presence of a concussion injury at the sideline and through recovery. More recently, research suggests that introducing a secondary cognitive retention task during tandem gait (i.e., dual task) may provide a better assessment of concussion. The purpose of this study was to determine if a tandem gait test paired with a 6-digit retention is a valid and reliable tool. Participants completed three trials of both the single-task (ST) and dual-task (DT) tandem gait tests, and their average (MEAN) and …
Geometric Visual Illusion Effects On Visual Perception And Visuomotor Control: Emphasis On The Vertical-Horizontal Illusion, Shijun Yan
LSU Doctoral Dissertations
The focus of this dissertation was to explore the effects of potential vertical-horizontal (V-H) illusory influences on perceptuomotor control. As part of this focus, we examined the potential use of separate cortical visual streams: the ventral visual stream for perception and the dorsal visual stream for action. Three studies were conducted to determine the effects of the V-H illusion influences on length estimations using upper limb point-to-point movements and lower limb stepping movements, involving various illusory configurations, movement directions, gaze directions. After a short introduction (Chapter 1) and a more detailed review of existing literature (Chapter 2), we present manuscripts …
Neuromechanical Tuning For Arm Motor Control, Russell Lee Hardesty Jr
Neuromechanical Tuning For Arm Motor Control, Russell Lee Hardesty Jr
Graduate Theses, Dissertations, and Problem Reports
Movement is a fundamental behavior that allows us to interact with the external world. Its importance to human health is most evident when it becomes impaired due to disease or injury. Physical and occupational rehabilitation remains the most common treatment for these types of disorders. Although therapeutic interventions may improve motor function, residual deficits are common for many pathologies, such as stroke. The development of novel therapeutics is dependent upon a better understanding of the underlying mechanisms that govern movement. Movement of the human body adheres to the principles of classic Newtonian mechanics. However, due to the inherent complexity of …
