In this work, a wearable system composed of four inertial devices (two SensHand and two SensFoot), and related processing algorithms for extracting parameters from limbs motion was tested on 40 healthy subjects and 40 PD patients. Seventy-eight and 96 kinematic parameters were measured from lower and upper limbs, respectively. Statistical and correlation analysis allowed to define four datasets that were used to train and test five supervised learning classifiers. Excellent discrimination between the two groups was obtained with all the classifiers (average accuracy ranging from 0.936 to 0.960) and all the datasets (average accuracy ranging from 0.953 to 0.966), over three conditions that included parameters derived from lower, upper or all limbs. The best performances (accuracy = 1.00) were obtained when classifying all the limbs with linear support vector machine (SVM) or gaussian SVM. Even if further studies should be done, the current results are strongly promising to improve this system as a support tool for clinicians in objectifying PD diagnosis and monitoring.<\/jats:p>","DOI":"10.3390\/s20092630","type":"journal-article","created":{"date-parts":[[2020,5,7]],"date-time":"2020-05-07T03:10:38Z","timestamp":1588821038000},"page":"2630","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":47,"title":["A Wearable System to Objectify Assessment of Motor Tasks for Supporting Parkinson\u2019s Disease Diagnosis"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7906-9013","authenticated-orcid":false,"given":"Erika","family":"Rovini","sequence":"first","affiliation":[{"name":"The BioRobotics Institute, Scuola Superiore Sant\u2019Anna, viale Rinaldo Piaggio 34, Pontedera, 56025 Pisa, Italy"},{"name":"Department of Excellence in Robotics &amp; AI, Scuola Superiore Sant\u2019Anna, Piazza Martiri della Libert\u00e0, 33, 56127 Pisa, Italy"}]},{"given":"Carlo","family":"Maremmani","sequence":"additional","affiliation":[{"name":"O.U.
