Electronic Thesis and Dissertation Repository
This dissertation explores a common, rehabilitative strategy for mitigating gait impairments in Parkinson’s disease (PD) called Rhythmic Auditory Stimulation (RAS). The effects of this intervention on gait in PD are well documented but highly variable, which poses difficulty for appropriate therapeutic application. Part of this variability may be related to individual musical abilities, such as beat perception accuracy, as most RAS interventions involve synchronizing with a beat. However, music is complex and variable. Therefore, factors inherent in the music itself may play a role in these differences, such as how much the music makes you want to move (groove), or …

© 2018 The Authors Parkinson's disease (PD) is a progressive neurological disorder that has no reliable biomarkers. The aim of this study was to explore the potential of semi-automated sub-regional analysis of the striatum with magnetic resonance imaging (MRI) to distinguish PD patients from controls (i.e., as a diagnostic biomarker) and to compare PD patients at different stages of disease. With 3 Tesla MRI, diffusion- and T1-weighted scans were obtained on two occasions in 24 PD patients and 18 age-matched, healthy controls. PD patients completed one session on and the other session off dopaminergic medication. The striatum was parcellated into …
