Here, we first introduce and validate a novel experimental paradigm using a virtual reality headset equipped with hand-tracking capabilities to facilitate the recordings of synchronized EMG signals and hand pose estimation. Using both the phasic and tonic EMG components of data acquired through the proposed paradigm, we compare hand gesture classification pipelines based on standard signal processing features, convolutional neural networks, and covariance matrices with Riemannian geometry computed from raw or xDAWN-filtered EMG signals. We demonstrate the performance of the latter for gesture classification using EMG signals. We further hypothesize that introducing physiological knowledge in machine learning models will enhance their performances, leading to better myoelectric prosthesis control. We demonstrate the potential of this approach by using the neurophysiological integration of the \u201cmove command\" to better separate the phasic and tonic components of the EMG signals, significantly improving the performance of sustained posture recognition. These results pave the way for the development of new cutting-edge machine learning techniques, likely refined by neurophysiology, that will further improve the decoding of real-time natural gestures and, ultimately, the control of myoelectric prostheses.<\/jats:p>","DOI":"10.3389\/fnins.2024.1329411","type":"journal-article","created":{"date-parts":[[2024,4,26]],"date-time":"2024-04-26T04:51:11Z","timestamp":1714107071000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":8,"title":["Machine learning for hand pose classification from phasic and tonic EMG signals during bimanual activities in virtual reality"],"prefix":"10.3389","volume":"18","author":[{"given":"C\u00e9dric","family":"Simar","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin","family":"Colot","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ana-Maria","family":"Cebolla","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mathieu","family":"Petieau","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guy","family":"Cheron","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gianluca","family":"Bontempi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2024,4,26]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"536","DOI":"10.1007\/978-3-642-21729-6_135","article-title":"\u201cNeural network classifier for hand motion detection from EMG signal,\u201d","author":"Ahsan","year":"2011","journal-title":"5th Kuala Lumpur International Conference on Biomedical Engineering 2011"},{"key":"B2","doi-asserted-by":"publisher","first-page":"24","DOI":"10.1016\/j.bspc.2016.01.011","article-title":"Distance and mutual information methods for EMG feature and channel subset selection for classification of hand movements","volume":"27","author":"Al-Angari","year":"2016","journal-title":"Biomed.
