This study is currently only open to active participants in the University of Rochester’s VALOR-PD study. The goal of this project is to identify objective, sensitive, and convenient measures for assessing early signs of Parkinson's disease in an at-risk population at home. We will do so by using a wireless sensor and analyzing the radio signals that bounce off patients' bodies, while patients go about their normal life without needing to wear sensors, answer questionnaires, or actively perform any tests.
