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 …
Mobility Of Individuals With Multiple Sclerosis And The Influence Of Physical Therapy, Brenda L. Davies
Mobility Of Individuals With Multiple Sclerosis And The Influence Of Physical Therapy, Brenda L. Davies
Theses & Dissertations
One main purpose was to explore the compensatory gait strategies of individuals with multiple sclerosis (MS). To address this purpose, we quantified the mechanical work generated by the lower extremity joints during walking. The outcomes from this investigation suggested that individuals with MS redistribute positive mechanical work during walking to the hip in order to compensate for a reduced ability of the ankle to generate positive mechanical work. Additionally, we also explored the motor control of the ankle as a potential contributing factor to the mobility limitations of individuals with MS. The outcomes from this investigation indicated that individuals with …

The Feedforward And Feedback Controls On Gait In Adults With Diabetes, Chun-Kai Huang
Theses & Dissertations
There are nearly 26 million people with diabetes mellitus (DM) in the US, and half of chronic DMs develop somatosensory deficits due to diabetic polyneuropathy or diabetic peripheral neuropathy (DPN). The absence or impaired somatosensory feedback (e.g. touch sensation or joint proprioception) resulted from the damage of large nerve fiber, and motor deficits such as attenuated muscle strength and abnormal plantar pressure of lower extremity have been identified in DPN, and these sensorimotor impairments lead to an increased number of falls. To reduce the risk of falling, a well-coordinated and adapted limb movement driven by the feedforward (anticipatory) and feedback …
