ParkinsonCheck A Decision Support System for Tremor Detection

The paper details the construction of a clinical decision support system which is the integral part of the ParkinsonCheck application. ParkinsonCheck is an app for smart phones built to detect signs of Parkinsons disease (PD) and essential tremor (ET), which is the main differential diagnosis from PD in the early stage of the disease. The application is based on spirography (spiral drawing) and uses the built-in decision support system to detect potential signs of the disease. The intention is to warn potential patients of their signs as early as possible and guide them to seek medical help. The decision support system is what separates ParkinsonCheck from similar apps which rely on sending the users data to a medical facility to be assessed by a neurologist. It enables our application to be fully automated. The focus of this paper are the inner workings of the decision support system which is used in two ways: (1) to detect the signs of PD and ET, and (2) to differentiate between PD and ET.
