Visual And Non-Visual Control Of Movement: The Role Of Proprioception In Upper Limb Function After Stroke, Nathan A. Baune Jan 2021

Visual And Non-Visual Control Of Movement: The Role Of Proprioception In Upper Limb Function After Stroke, Nathan A. Baune

Arts & Sciences Electronic Theses and Dissertations

This dissertation presents a series of studies into human reach and grasp, focusing on the neural systems and behaviors of upper-limb action that underly performance under varied sensory conditions: specifically, acting with and without visual feedback of the limb and under typical or impaired proprioceptive sensation (proprioceptive decline with aging and proprioceptive deficit following stroke). Under typical conditions, a combination of visual and non-visual (e.g., proprioception) sources of information are used to guide action. In the instance of stroke survivors or elderly individuals with proprioceptive deficits/decline, there may be a necessary reliance on visual information to perform. The studies are …


Wheelchair Propulsion For Everyday Manual Wheelchair Users: Repetition Training And Machine Learning-Based Monitoring, Pin-Wei Chen Dec 2019

Wheelchair Propulsion For Everyday Manual Wheelchair Users: Repetition Training And Machine Learning-Based Monitoring, Pin-Wei Chen

Arts & Sciences Electronic Theses and Dissertations

Upper limb pain and injuries are prevalent among manual wheelchair users and can restrict their participation and daily activities. Due to the high repetition and force in wheelchair propulsion, chronic wheelchair propulsion has been linked to the risk of upper limb pain and injury. Prevention of upper limb pain and injury is a high priority in wheelchair-related research. Decades of research in wheelchair propulsion biomechanics have led to clinical practice guidelines (CPG). Unfortunately, a decade after the publication of the CPG, CPG-recommended propulsion is still uncommon. Hence, for the first aim, a randomized controlled trial pilot study with two groups …


Adapting The Lifestyle-Integrated Functional Exercise Program For Medically Underserved Older Adults, Yi-Ling Hu May 2019

Adapting The Lifestyle-Integrated Functional Exercise Program For Medically Underserved Older Adults, Yi-Ling Hu

Arts & Sciences Electronic Theses and Dissertations

Falls are a growing public health problem among the aging population. Structured exercise programs are effective in preventing falls, and many have been implemented for community-dwelling older adults in the U.S. However, low adherence rates for structured exercise are reported consistently for this population. The need to translate alternative evidence-based exercise programs the diverse older adult population is important. One promising alternative program, the Lifestyle-integrated Functional Exercise Program (LiFE), can significantly reduce falls but has not yet been implemented for diverse older adults residing in the US. To initiate the translation of LiFE, we targeted older adults residing in medically …


Prospective Memory Impairment In Parkinson Disease Without Dementia: Cognitive Mechanisms And Intervention, Erin R. Foster May 2018

Prospective Memory Impairment In Parkinson Disease Without Dementia: Cognitive Mechanisms And Intervention, Erin R. Foster

Arts & Sciences Electronic Theses and Dissertations

Cognitive impairment among non-demented individuals with Parkinson disease (PD) produces significant disability, reduced quality of life, and restricted participation. This dissertation will cover PD-related impairment in prospective memory, or the ability to remember to execute delayed intentions at the appropriate moment in the future. Prospective memory impairment in PD is increasingly recognized as a functionally and clinically relevant problem and viable target for cognitive intervention. To lay the groundwork for the development of effective interventions for prospective memory in PD, this dissertation examines the cognitive mechanisms underlying prospective memory impairment in PD and the potential of training in a targeted …


Vrshape: A Virtual Reality Tool For Shaping Movement Compensation, Matthew Hale Foreman May 2017

Vrshape: A Virtual Reality Tool For Shaping Movement Compensation, Matthew Hale Foreman

Arts & Sciences Electronic Theses and Dissertations

The majority of persons living with chronic stroke experience some form of upper extremity motor impairment that affects their functional movement, performance of meaningful activities, and participation in the flow of daily life. Stroke survivors often compensate for these impairments by adapting their movement patterns to incorporate additional degrees of freedom at new joints and body segments. One of the most common compensatory movements is the recruitment of excessive trunk flexion when reaching with the affected upper extremity. Long-term use of these compensations may lead to suboptimal motor recovery and chronic pain or injury due to overuse. Rehabilitation focuses on …


The Feasibility Of Using Metacognitive Strategy Training To Improve Performance, Foster Participation, And Reduce Impairment Following Neurological Injury, Timothy J. Wolf May 2016

The Feasibility Of Using Metacognitive Strategy Training To Improve Performance, Foster Participation, And Reduce Impairment Following Neurological Injury, Timothy J. Wolf

Arts & Sciences Electronic Theses and Dissertations

Executive function is central to our ability to learn and participate in everyday life activities and rehabilitation outcomes for individuals with executive dysfunction after neurological injury are poor. The impairments and performance challenges these individuals experience are typically not identified appropriately so they often do not receive adequate rehabilitation and can have significant challenges returning to complex everyday life activities. The vast majority of rehabilitation efforts to support individuals with neurological injuries with executive dysfunction are based on a restoration model that aims to improve cognitive function with the expectation that these gains will translate to everyday life. The available …
