Summary
Background: Medical treatment in patients suffering from Parkinson’s disease is very difficult
as dose-finding is mainly based on selective and subjective impressions by the physician.
Objectives: To allow for the objective evaluation of patients’ symptoms required for optimal
dose-finding, a telemonitoring system tracks the motion of patients in their surroundings.
The system focuses on providing interoperability and usability in order to ensure
high acceptance.
Methods: Patients wear inertia sensors and perform standardized motor tasks. Data are recorded,
processed and then presented to the physician in a 3D animated form. In addition,
the same data is rated based on the UPDRS score. Interoperability is realized by developing
the system in compliance with the recommendations of the Continua Health Alliance.
Detailed requirements analysis and continuous collaboration with respective user groups
help to achieve high usability.
Results: A sensor platform was developed that is capable of measuring acceleration and angular
rate of motions as well as the absolute orientation of the device itself through an
included compass sensor. The system architecture was designed and required infrastructure,
and essential parts of the communication between the system components were implemented
following Continua guidelines. Moreover, preliminary data analysis based on three-dimensional
acceleration and angular rate data could be established.
Conclusion: A prototype system for the telemonitoring of Parkinson’s disease patients was successfully
developed. The developed sensor platform fully satisfies the needs of monitoring patients
of Parkinson’s disease and is comparable to other sensor platforms, although these
sensor platforms have yet to be tested rigorously against each other. Suitable approaches
to provide interoper-ability and usability were identified and realized and remain
to be tested in the field.
