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 …
