We analyzed the performance achieved by the automatic UPDRS scoring system and compared the estimated UPDRS evaluation with the one performed by neurologists, showing that the proposed system compares favorably with typical inter-rater variability. We then investigated the correlations between the UPDRS scores assigned to the various tasks by both the neurologists and the automatic system. The results, based on a limited number of subjects with Parkinson’s Disease (PD) (34 patients, 47 clinical trials), show poor-to-moderate correlations between the UPDRS scores of different tasks, highlighting that the patients’ motor performance may vary significantly from one task to another, since different tasks relate to different aspects of the disease. An aggregate UPDRS score is also considered as a concise parameter which can provide additional information on the overall level of the motor impairments of a Parkinson’s patient.

abstract = {Vehicular data collection applications are emerging as an appealing technology to monitor urban areas, where a high concentration of connected vehicles with onboard sensors is a near future scenario. In this context, smartphones are, on one side, effective enablers of Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) applications and, on the other side, highly sophisticated sensing platforms. In this paper, we introduce an effective and efficient system, denoted as D4V, to disseminate vehicle-related information and sensed data using smartphones as V2I devices. D4V relies on a Peer-to-Peer (P2P) overlay scheme, denoted as Distributed Geographic Table (DGT), which unifies the concepts of physical and virtual neighborhoods in a scalable and robust infrastructure for application-level services. First, we investigate the discovery procedure of the DGT overlay network, through analytical and simulation results. Then, we present and discuss an extensive simulation-based performance evaluation (considering relevant performance indicators) of the D4V system, in a 4G wireless communication scenario. The simulation methodology combines DEUS (an application-level simulation tool for the study of large-scale systems) with ns-3 (a well-known network simulator, which takes into account lower layers), in order to provide a D4V proof-of-concept.

Vehicular data collection applications are emerging as an appealing technology to monitor urban areas, where a high concentration of connected vehicles with onboard sensors is a near future scenario. In this context, smartphones are, on one side, effective enablers of Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) applications and, on the other side, highly sophisticated sensing platforms. In this paper, we introduce an effective and efficient system, denoted as D4V, to disseminate vehicle-related information and sensed data using smartphones as V2I devices. D4V relies on a Peer-to-Peer (P2P) overlay scheme, denoted as Distributed Geographic Table (DGT), which unifies the concepts of physical and virtual neighborhoods in a scalable and robust infrastructure for application-level services. First, we investigate the discovery procedure of the DGT overlay network, through analytical and simulation results. Then, we present and discuss an extensive simulation-based performance evaluation (considering relevant performance indicators) of the D4V system, in a 4G wireless communication scenario. The simulation methodology combines DEUS (an application-level simulation tool for the study of large-scale systems) with ns-3 (a well-known network simulator, which takes into account lower layers), in order to provide a D4V proof-of-concept. The observed results show that D4V-based information sharing among vehicles allows to significantly reduce risks and nuisances (e.g., due to road defects and congestions).
