Electromyography (EMG) is a technique for evaluating and recording the electrical 
activity produced by skeletal muscles. Since the contracting skeletal muscles are 
greatly responsible for loading of the bones and joints, information about the muscle 
EMG is important to gain knowledge about muscular-skeletal biomechanics.
Myoelectric signals can also demonstrate the development of loading imbalance and 
asymmetry, which in turn relates to physical disability. EMG may be used clinically 
for the diagnosis of neuromuscular problems and for assessing biomechanical and 
motor control deficits and other functional disorders. Furthermore, it can be used as a 
control signal for interfacing with orthotic and/or prosthetic devices or other 
rehabilitation assists and – aside from muscular activity - EMG can be used to indicate 
and quantify the development of muscle fatigue.
A great challenge in biomedical engineering is to non-invasively assess the 
physiological changes occurring in different internal organs of the human body. These 
variations can be modeled and measured often as biomedical source signals that 
indicate the function or malfunction of various physiological systems. To extract the 
relevant information for diagnosis and therapy, expert knowledge in medicine and 
engineering is required. Biomedical source signals, especially EMG, are usually weak, 
stationary signals and distorted by noise and interference. Moreover, they are usually 
mutually superimposed. Besides classical signal analysis tools (such as adaptive 
supervised filtering, parametric or non-parametric spectral estimation, time frequency 
analysis, and higher order statistics), Intelligent Signal Processing techniques are used 
for pre-processing, noise and artefact reduction, enhancement, detection and 
estimation of EMG signals by taking into account their spatio-temporal correlation and 
mutual statistical dependence.
This book is aimed to provide a self-contained introduction to the subject as well as 
offering a set of invited contributions, which we see as lying at the cutting edge of both 
empirical and computational aspects of EMG research. This book was born from 
discussions with researchers in the EMG community and aims to provide a snapshot 
of some current trends and future challenges in EMG research.
Book presents an updated overview of signal processing applications and recent 
developments in EMG from a number of diverse aspects and various applications in 
clinical and experimental research. It will provide readers with a detailed introduction 
to EMG signal processing techniques and applications, while presenting several new 
results and explanation of existing algorithms. Furthermore, the research results 
previously scattered in many scientific journals and conference papers worldwide, are 
methodically collected and presented in the book in a unified form. The book is likely 
to be of interest to graduate and postgraduate students, neurologists, engineers and
scientists - in the field of neural signal processing and biomedical engineering. This 
book is organized into 18 chapters, covering the current theoretical and practical 
approaches of EMG research. Although these chapters can be read almost 
independently, they share the same notations and the same subject index. Moreover, 
numerous cross- references link the chapters to each other.
As an Editor and also an Author in this field, I am privileged to be editing a book with 
such fascinating topics, written by a selected group of gifted researchers. I would like 
to extend my gratitude to the authors, who have committed so much effort to the 
publication of this book.
