Abstract—We present work to develop a wireless wearable
sensor system for monitoring patients with Parkinson’s disease
(PD) in their homes. For monitoring outside the laboratory, a
wearable system must not only record data, but also efficiently
process data on-board. This manuscript details the analysis of
data collected using tethered wearable sensors. Optimal
window length for feature extraction and feature ranking were
calculated, based on their ability to capture motor fluctuations
in persons with PD. Results from this study will be employed to
develop a software platform for the wireless system, to
efficiently process on-board data.
