Abstract: Patients with Parkinson's disease (PD) have declines in executive function and attention that are accompanied by postural instability and gait dysfunction (PIGD).PIGD and cognitive deficits are debilitating symptoms in PD patients, which become more pronounced during performance of complex tasks, such as performing two concurrent tasks.A significant gap remains in the ability to effectively characterize postural instability in individuals with PD.Clinical evaluation of postural declines is largely subjective while objective biomechanical approaches are expensive and time consuming, thus limiting clinical adoption.Recent advances in mobile devices present an opportunity to address the gap in the quantification of postural stability with and without a concurrent cognitive task.The goal of this dissertation was to determine if a mobile device (Apple iPad) could be used to accurately characterize postural stability and cognitive function under various levels of difficulty and detect differences in performance between individuals with PD and healthy older adults.In Study 1, 17 patients with PD and 17 controls completed a series of postural stability tasks.The motion analysis system and mobile device provided similar measures of stability across groups and kinematic data were capable of discriminating patients from controls.In Study 2, 14 patients with PD and 14 controls completed the Sensory Organization Test (NeuroCom International).Center of vii
