Chapter 1: About ParkinSense
General Device Description
The ParkinSense movement disorder assessment system can be utilized for a wide variety of
applications to quantify motion and electrical muscle activity. The system includes a user worn
unit, a radio for wireless data transmission, and software to collect, manage, and analyze data.
The ParkinSense user unit is typically worn on the wrist and finger of a subject (Figure 1). The
wrist module slips over a comfortable band worn around the wrist or forearm. A sensor module
then slips over the middle finger of a subject. ParkinSense provides a total of eight channels of
data including three channels of accelerometry, three channels of gyroscopes, and two channels
of electromyography (EMG). The system measures three dimensional motion using three
orthogonal accelerometers and three orthogonal gyroscopes located in the sensor module. The
system also measures two channels of EMG. The lemo connector input on the wrist module
provides connection for the two channel EMG snap leads which come with the system.
