Abstract

Myoelectric control consists in the recording of EMG signals for extracting control signals to command external devices, such as hand prostheses. In commercial systems, the intensity of muscle activity is extracted from the EMG and used for single degree of freedom activation (direct control). Over the past 60 years, the academic research has progressed to more sophisticated approaches but, surprisingly, none of these academic achievements has been implemented in commercial systems so far. The academic state-of-the-art relies on pattern recognition as a method to control multiple motor tasks using a relatively small number of electrodes. After several decades of development, this approach still shows major limitations, thus a change of focus on myocontrol research may be needed. Novel approaches, recently proposed, include techniques for simultaneous and proportional control of multiple degrees of freedom, which are based on regression methods. Moreover, it seems evident that the exclusive use of EMG as a source for feed-forward control of prostheses poses important limitations. These limits can be partly overcome by including additional sensors, within semiautonomous systems. Finally, sensory feedback is essential in prosthetic control, thus there is the need to introduce robust and intuitive methods for sensory substitution. The talk will cover these approaches with a discussion on the major challenges in filling the gap between commercial/clinical and academic methods for myocontrol.

Speaker Biography

Dario Farina received the M.Sc. degree in electronics engineering from Politecnico di Torino, Torino, Italy, in 1998, and the Ph.D. degrees in automatic control and computer science and in electronics and communications engineering from the Ecole Centrale de Nantes, Nantes, France, and Politecnico di Torino, respectively, in 2002. During 2002–2004, he was a Research Assistant Professor at Politecnico di Torino and in 2004–2008 an Associate Professor in Biomedical Engineering at Aalborg University, Aalborg, Denmark. From 2008 to 2010, he was Full Professor in Motor Control and Biomedical Signal Processing and Head of the Research Group on Neural Engineering and Neurophysiology of Movement at Aalborg University. In 2010, he was appointed Full Professor and Founding Chair of the Department of Neurorehabilitation Engineering, University Medical Center Göttingen, Georg-August University, Germany, within the Bernstein Center for Computational Neuroscience. He is also the Chair for Neuroinformatics of the Bernstein Focus Neurotechnology Göttingen.
His research focuses on biomedical signal processing, modeling, neurorehabilitation technology, and neural control of movement. Within these areas, he has (co)-authored approximately 300 papers in peer-reviewed journals and over 300 among conference papers/abstracts, book chapters, and encyclopedia contributions. He is also an Editor of the book “Introduction to Neural Engineering for Motor Rehabilitation” (IEEE/Wiley). He is an Associate Editor of Medical & Biological Engineering & Computing and of the Journal of Electromyography and Kinesiology and member of the Editorial Board of the Journal of Neuroscience Methods.
Dr. Farina has been the Vice-President of the International Society of Electrophysiology and Kinesiology (ISEK) from 2010 to 2012 and is currently President of ISEK. Among other recognitions and awards, he has been the recipient of the 2010 IEEE Engineering in Medicine and Biology Society Early Career Achievement Award for his contributions to biomedical signal processing and to electrophysiology and has been elected IEEE Engineering in Medicine and Biology Distinguished Lecturer for the term 2014-2015. He is an Associate Editor of IEEE TRANSACTIONS ON BIOMEDICAL ENGINEERING and of IEEE TRANSACTIONS ON NEURAL SYSTEMS AND REHABILITATION ENGINEERING.
