SMARTPHONES FOR ASSESSING PARKINSON'S DISEASE TREMOR

 CLICK HERE FOR A PRINTABLE OR WHITE BACKGROUND VERSION OF THIS ARTICLE

The assessment of Parkinson's Disease and the treatments that sohould 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. For more information concerning use of mobile phone accelerometers for tremor go to :  Mobile phone accelerometers

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.
