However, the accurate measurement of complex hand movements and the decoding of dynamic movement data remains challenging. Here, we introduce two algorithms, one based on support vector machine (SVM) classification combined with dynamic time warping, and the other based on a long short-term memory (LSTM) neural network, which were designed to discriminate small differences in defined sequences of hand movements. We recorded hand movement data from 17 younger and 17 older adults using an exoskeletal data glove while they were performing six different movement tasks. Accuracy rates in decoding the different movement types were similarly high for SVM and LSTM in across-subject classification, but, for within-subject classification, SVM outperformed LSTM. The SVM-based approach, therefore, appears particularly promising for the development of movement decoding tools, in particular if the goal is to generalize across age groups, for example for detecting specific motor disorders or tracking their progress over time.<\/jats:p>","DOI":"10.3390\/s22166101","type":"journal-article","created":{"date-parts":[[2022,8,15]],"date-time":"2022-08-15T23:44:03Z","timestamp":1660607043000},"page":"6101","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Discriminating Free Hand Movements Using Support Vector Machine and Recurrent Neural Network Algorithms"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8649-9791","authenticated-orcid":false,"given":"Christoph","family":"Reichert","sequence":"first","affiliation":[{"name":"Department of Behavioral Neurology, Leibniz Institute for Neurobiology, Brenneckestr. 6, 39118 Magdeburg, Germany"},{"name":"Center for Behavioral Brain Sciences (CBBS), Universitaetsplatz 2, 39106 Magdeburg, Germany"},{"name":"Forschungscampus STIMULATE, Otto-Hahn-Str. 2, 39106 Magdeburg, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3504-9966","authenticated-orcid":false,"given":"Lisa","family":"Klemm","sequence":"additional","affiliation":[{"name":"Department of Neurology, University Medical Center, Leipziger Str. 44, 39120 Magdeburg, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6856-4617","authenticated-orcid":false,"given":"Raghava Vinaykanth","family":"Mushunuri","sequence":"additional","affiliation":[{"name":"Faculty of Computer Science, Otto-von-Guericke University, Universitaetsplatz 2, 39106 Magdeburg, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9044-9255","authenticated-orcid":false,"given":"Avinash","family":"Kalyani","sequence":"additional","affiliation":[{"name":"Institute for Cognitive Neurology and Dementia Research (IKND), Otto-von-Guericke University, Leipziger Str. 44, 39120 Magdeburg, Germany"},{"name":"German Center for Neurodegenerative Diseases (DZNE), Leipziger Str. 44, 39120 Magdeburg, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4439-4374","authenticated-orcid":false,"given":"Stefanie","family":"Schreiber","sequence":"additional","affiliation":[{"name":"Center for Behavioral Brain Sciences (CBBS), Universitaetsplatz 2, 39106 Magdeburg, Germany"},{"name":"Department of Neurology, University Medical Center, Leipziger Str. 44, 39120 Magdeburg, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3169-1951","authenticated-orcid":false,"given":"Esther","family":"Kuehn","sequence":"additional","affiliation":[{"name":"Center for Behavioral Brain Sciences (CBBS), Universitaetsplatz 2, 39106 Magdeburg, Germany"},{"name":"Institute for Cognitive Neurology and Dementia Research (IKND), Otto-von-Guericke University, Leipziger Str. 44, 39120 Magdeburg, Germany"},{"name":"German Center for Neurodegenerative Diseases (DZNE), Leipziger Str. 44, 39120 Magdeburg, Germany"},{"name":"Hertie Institute for Clinical Brain Research (HIH), Otfried Mueller-Str. 27, 72076 Tuebingen, Germany"}]},{"given":"Elena","family":"Aza\u00f1\u00f3n","sequence":"additional","affiliation":[{"name":"Department of Behavioral Neurology, Leibniz Institute for Neurobiology, Brenneckestr. 6, 39118 Magdeburg, Germany"},{"name":"Center for Behavioral Brain Sciences (CBBS), Universitaetsplatz 2, 39106 Magdeburg, Germany"},{"name":"Department of Neurology, University Medical Center, Leipziger Str. 44, 39120 Magdeburg, Germany"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"838191","DOI":"10.3389\/fneur.2022.838191","article-title":"An Automated Tongue Tracker for Quantifying Bulbar Function in ALS","volume":"13","author":"Northall","year":"2022","journal-title":"Front.
