The number of elderly people in European population is becoming higher year after year, thus, increasin. The number of people affected by neurodegenerative diseases. The early diagnosis and treatment of these patients is a critical aspect yet not covered in depth. In this paper we propose a novel system for the monitorization of gait of patients affected by Parkinson disease (PD). Force Sensitive Resistors (FSR) are used, embedding them in an insole, which allow. The capture and analysis oy the gait over long periods of time and whil. The patient interacts with a natural (non-controlled) environments. The medical doctors are able to visualize and analyz. The signals using a PC application, in order to obtain conclusions. This work is being developed i. The framework of PERFORM1 project, which is financed by the European Commission and wit. The participation oy the University Hospital of Navarra2. ©2009 IEEE.
