| Background: |
Epilepsy, with a prevalence of 0.5 - 1.0% , can be assumed to be
one of the most common chronic diseases. Epilepsy patients suffer
from decreased quality of life. This is mostly due to the significant
characteristic of epilepsy which is the occurrence of paroxysmal
seizures. Such seizures occur without any warning and cause a total
loss of the affected patients over their bodies for several minutes.

|
| Objectives: |
Development of a comprehensive accelerometer-based
system for the convenient yet robust acquisition and analysis of epileptic
seizure motion data. |
| |
|
| Methods: |
The system was developed based on requirements that were collected
using a combined approach of literature review and qualitative expert
interviews. Mainly open-source solutions were applied allowing for
a cost-efficient development process. We chose the motion sensor
ADXL 330 from Analog Devices that is used in the controller of the
gaming console Nintendo Wii®, also called WiiRemote®. The characteristics
of the WiiRemote are promising for a first prototype, as it is cheap
and easily available.
|
| |
|
| Results: |
A motion data acquisition interface was implemented that is able
to simultaneously acquire the motion data of several WiiRemotes®
that are con-nected via Bluetooth. A data analysis system was developed
that provides the user with an adequate visual representation of
the motion data and also possibilities to manipulate this data with
basic mathematical functions.
At the moment, real data from four epileptic seizures have been
gathered by the prototype. This data is just being analysed.
