Parkinson's Disease (PD) is classified as a progressively degenerative movement disorder, affecting approximately 0.2% of the population and resulting in decreased performance in a wide variety of activities of daily living. Motivated by needs associated with the conduct of multi-center clinical trials, early detection, and the optimization of routine management of individuals with PD, we have developed a three-tiered approach to evaluation of PD and other neurologic diseases/disorders. One tier is characterized as “web-based evaluation”, consisting of objective performance capacity tests and subjective questionnaires that target history and symptom evaluation. Here, we present the initial evaluation of three representative, self-administered, objective, web-based performance capacity tests (simple visual-hand response speed, rapid alternating movement quality, and upper extremity neuromotor channel capacity). Twenty-one subjects (13 with PD, 8 without neurologic disease) were evaluated. Generally good agreement was obtained with lab-based tests executed with an experienced test administrator. We conclude that objective performance capacity testing is a feasible component of a web-based evaluation for PD, providing a sufficient level of fidelity to be useful.
