In this context, we have developed a self-managed system for the automated assessment of the PD upper limb motor tasks as specified by the Unified Parkinson\u2019s Disease Rating Scale (UPDRS). The system is built around a Human Computer Interface (HCI) based on an optical RGB-Depth device and a replicable software. The HCI accuracy and reliability of the hand tracking compares favorably against consumer hand tracking devices as verified by an optoelectronic system as reference. The interface allows gestural interactions with visual feedback, providing a system management suitable for motor impaired users. The system software characterizes hand movements by kinematic parameters of their trajectories. The correlation between selected parameters and clinical UPDRS scores of patient performance is used to assess new task instances by a machine learning approach based on supervised classifiers. The classifiers have been trained by an experimental campaign on cohorts of PD patients. Experimental results show that automated assessments of the system replicate clinical ones, demonstrating its effectiveness in home monitoring of PD.<\/jats:p>","DOI":"10.3390\/s18103523","type":"journal-article","created":{"date-parts":[[2018,10,18]],"date-time":"2018-10-18T10:55:41Z","timestamp":1539860141000},"page":"3523","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":42,"title":["A Self-Managed System for Automated Assessment of UPDRS Upper Limb Tasks in Parkinson\u2019s Disease"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5381-4794","authenticated-orcid":false,"given":"Claudia","family":"Ferraris","sequence":"first","affiliation":[{"name":"Institute of Electronics, Computer and Telecommunication Engineering, National Research Council, 10129 Torino, Italy"},{"name":"Department of Neurosciences, University of Turin, 10124 Torino, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6728-2239","authenticated-orcid":false,"given":"Roberto","family":"Nerino","sequence":"additional","affiliation":[{"name":"Institute of Electronics, Computer and Telecommunication Engineering, National Research Council, 10129 Torino, Italy"}]},{"given":"Antonio","family":"Chimienti","sequence":"additional","affiliation":[{"name":"Institute of Electronics, Computer and Telecommunication Engineering, National Research Council, 10129 Torino, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0547-0143","authenticated-orcid":false,"given":"Giuseppe","family":"Pettiti","sequence":"additional","affiliation":[{"name":"Institute of Electronics, Computer and Telecommunication Engineering, National Research Council, 10129 Torino, Italy"}]},{"given":"Nicola","family":"Cau","sequence":"additional","affiliation":[{"name":"Department of Electronics, Information and Bioengineering, Politecnico di Milano, 20133 Milano, Italy"},{"name":"Department of Neurology and NeuroRehabilitation, Istituto Auxologico Italiano, IRCCS, S.
