Electromyography (EMG) is a technique for evaluating and recording the electrical activity produced by skeletal muscles. EMG is used for the diagnosis of neuromuscular issues and for determining biomechanical and motor control deficiency and other functional disorders. Moreover, it can be applied as a control signal for interfacing with orthotic and/or prosthetic devices or other rehabilitation aids. It will provide readers with a comprehensive introduction to EMG signal processing techniques and applications, while presenting several new results and explanation of existing algorithms. This book encompasses the analysis of theoretical and practical approaches of EMG research.
