The assessment of Parkinson's Disease and the treatments that should be used for it are
dependent on the quantification of symptoms such as tremor. A new system has been
proposed for mobile phone applications, in which the mobile phone assesses the level and
frequency of a person's tremor. . The system is based on measuring the acceleration from the
hand of the person with Parkinson's Disease using a mobile cell phone accelerometer.
Recordings were made from an equal number of
people with and without Parkinson's Disease. The
recordings were analysed using a two level wavelet
packet analysis. Features were extracted forming a
feature vector of 12 different elements. The features
extracted from the subjects were classified using a
neural networks classifier. The results obtained showed
an accuracy of 95%. These results indicate that a cell
phone accelerometer can accurately detect and record
rest tremor in people with Parkinson's Disease.
