This book on Electromyography focuses on key principles of using and examining EMG and encompasses a broad range of subjects including Principles and Methods, Signal Processing, and Diagnostics. The authors have varied in their approach to their subjects, from reviews on different aspects of the field to experimental studies with exciting new findings. The experts have analyzed literature related to applied surface electromyography parameters for evaluating muscle function and fatigue to the constraints of different analysis and processing techniques. It also describes emerging applications where electromyography is employed as a means to regulate electromechanical systems, water surface electromyography, scanning electromyography, EMG measures in orthodontic appliances and in ophthalmological field. These original approaches to the usage of EMG measurement will be of great interest to readers. 3
