This is an 8 week observational study to evaluate the feasibility of using remote monitoring technologies in future studies of PD. The study will 2 clinical evaluations (one initial, one final), and an 8-week monitoring period including 4 virtual visits where participants will use a combination of digital devices (Emerald touchless sensor system with associated ankle accelerometer, iPhone, Apple Watch, iPad, Fitbit Aria, FitBit Versa, Withings Blood Pressure Monitor Connect, and/or Withings Sleep Mat) during their daily lives.

This study will enroll at least 25 dyads consisting of participants with PD and their care partners recruited from multiple clinical practices and the general public.

Enrollment will be enriched to ensure that participants are distributed across mild to severe PD.
