This lecture will cover the nature of EMG signals and the different methods of data collection. There will be a particular focus on processing techniques of EMG and what information can be obtained with relevance to muscle control and performance. The lecture will also present a new technology, Decomposition of surface EMG signals (dEMG), which automatically decomposes a complex surface EMG signal into the trains of action potentials belonging to individual motor units in an accurate and reliable manner. The technology provides parameters which are of primary importance for studies of motor unit control, such as the firing statistics of motor units, the timing of activation of individual motor units, and the shape of their action potentials. We will illustrate how this novel technology can be used to expand our understanding of motor unit properties and control strategies, and how the results of this technology can be validated. We will present current research studies using the technology and its applications in the field of motor control. This lecture will include live data collection and demonstrations of the methods and measurements with a focus on clinical application and an exploration of some of the complications and confounding factors when using EMG.

Jim Richards was appointed Professor in Biomechanics and research lead for Allied Health Professions at University of Central Lancashire in 2004. Professor Richards work includes the clinical application of biomechanics, the development of new assessment tools for chronic disease, conservative and surgical management of orthopaedic and neurological conditions, and development of evidence based approaches for improving clinical management and rehabilitation. Professor Richards has authored over 200 papers and written and edited a number of textbooks including Biomechanics in Clinic and Research (2008) and the 5th edition of Whittle’s Gait Analysis (2012). He has also contributed to Tidy’s Physiotherapy (2003, 2008, 2012), the 10th edition of Mercer’s Textbook of Orthopaedics and Trauma (2012) and Experimental Research Methods: A Guidebook for Studies in Trauma Care (2014).
