  • EMG Modeling and Simulation

    This chapter outlines the main components that should be considered in the development of physiologically based models of surface electromyographic (sEMG). One of the challenges in increasing the accuracy of current sEMG models is the correct identification of the model parameters. Parameter identification is particularly difficult for systems such as this in which it is not possible to accurately measure all of the physiological, anatomical, and physical properties of the system. The chapter explores the simulation of intramuscular EMG, in particular for clinical applications. One of the primary purposes of a modeling approach is to identify the mechanisms responsible for experimental observations. A successful EMG model can thereby help the researcher to relate the recorded electrical signal to the underlying processes associated with muscle contraction. Model validation remains one of the most challenging areas in EMG modeling.

  • Muscle Coordination, Motor Synergies, and Primitives from Surface EMG

    To investigate neural control strategies, muscle activity must be measured during motor behavior. Recent advances in the investigation of the neural control of movement have led to a re-examination of the mechanisms of sensorimotor integration in the central nervous system (CNS) and in the spinal circuitry in particular. This chapter considers different approaches used to uncover the modular organization of the motor output in human behaviors such as responding to postural perturbations, reaching with the arm, and locomotion, as well as its plasticity and flexibility in movement disorders. It also investigates the strategies that the CNS employs to coordinate the activation of many muscles start from electromyographic (EMG) signals recorded simultaneously from many muscles. Different muscle synergies models are used to decompose the EMG envelopes using appropriate factorization algorithms. The chapter further considers the spatiotemporal organization of the activity patterns of leg and trunk muscles during locomotion.

  • Surface Electromyography for MAN-Machine Interfacing in Rehabilitation Technologies

    This chapter describes the use of surface electromyography (EMG) for establishing intuitive man-machine interfaces for rehabilitation settings and technologies. The EMG is primarily used as source of neural information, to provide control signals for external devices. The chapter also describes the general concepts underlying the extraction of control signals from surface EMG recordings. It presents examples of neurorehabilitation technologies based on surface EMG. The surface EMG signal can be used to trigger or continuously control external assistive devices including powered orthoses and prostheses. The chapter outlines representative examples of neurotechnologies that make use of EMG signals for device control purposes. It provides examples in the three main areas of neurorehabilitation: replacement, restoration, and neuromodulation. EMG signals were recorded from seven muscles including: vastus medialis, vastus lateralis, rectus femoris, lateral hamstrings, medial hamstrings, gastrocnemius medialis, and gastrocnemius lateralis.

  • Detection and Conditioning of Surface EMG Signals

    This chapter presents the detection and conditioning of surface electromyographic (EMG) signals. More advanced techniques are now widely used in research laboratories and are being adopted in clinical settings. Such techniques are based on multichannel detection by means of one dimensional (1-D) or two dimensional (2-D) electrode arrays. The chapter describes the electrode-skin interface and the front-end amplifier stage. The impedance between two electrodes is the sum of two electrode-skin impedances plus the interposed tissue impedance. Conventional electrodes, either wet or dry, behave like transducers converting ionic current (in tissue and gel) into flow of electrons in the metal. These electrical sensors require a careful skin preparation to reduce the impedance and noise associated to this interface. The biomedical sector offers small-sized, high-cost application-specific integrated circuits (ASIC) devices for biopotential measurements. Applications are expected to range from physiopathological investigations, to rehabilitation games, biofeedback applications, and sport training.

  • Techniques for Information Extraction from the Surface EMG Signalhigh-Density Surface EMG

    This chapter deals with the information that can be extracted from images obtained when electrode grids are applied to the skin above muscles with different architectures. The interpretation of these images, and therefore the information obtainable, depends on the muscle architecture and fiber arrangement. The action potentials propagating along muscle fibers generate electric fields in the surrounding conductive medium. The chapter deals with the surface EMG instantaneous images, with the feature images, and with the spatiotemporal images. It provides examples on the information that may be obtained from high-density surface EMG (HD-EMGs) detected from muscles with pinnate architecture. Two main fields of research application of HDsEMG may be identified such as surface EMG imaging and surface EMG decomposition. From the clinical point of view, the expected developments concern more extensive applications in biofeedback and monitoring of the neuromuscular system for prevention purposes and automatic detection of the innervation zone.

  • Surface EMG Decomposition

    This chapter provides an overview of surface EMG decomposition techniques, along with their basic assumptions, properties, and limitations. Surface electrodes measure the electrical activity of several nearby muscle fibers that are active during a muscle contraction. The electrical activity of each fiber can be described by a single fiber action potential (SFAP) that propagates from the neuromuscular junction towards the tendons. There is large diversity of decomposition techniques that can roughly be categorized either as template matching or latent component analysis (blind source separation) approaches. Decomposition of surface EMG is a powerful tool enabling noninvasive insight not only into muscle control strategies, but also into peripheral muscle properties. It provides unambiguous information on physiological parameters of individual motor units that can easily be interpreted. The identification of motor units (MUs) discharge patterns from surface EMG signals, acquired during dynamic muscle contractions, needs to be addressed.

  • Electromyography-Driven Modeling for Simulating Subject-Specific Movement at the Neuromusculoskeletal Level

    This chapter provides a comprehensive description of subject-specific electromyography (EMG)-driven musculoskeletal models for the human lower extremity. EMG-driven modeling requires experimental human motion data to be captured for model calibration and operation. A musculoskeletal model is created from medical imaging data of bone and muscle surfaces, such as magnetic resonance imaging (MRI) or computed tomography. The multi-degrees of freedom (DOFs) model comprises five main components: musculotendon kinematics, musculotendon activation, musculotendon dynamics, moment computation, and model calibration. The chapter demonstrates the use of EMG-driven modeling to predict musculotendon units (MTUs) forces and the resulting joint moments about multiple DOFs during dynamic motor tasks. It outlines the use of EMG- driven modeling for applications in neurorehabilitation technologies. EMG- driven methodologies can be successfully applied to study dynamic tasks that involve muscle co-contraction. EMG-informed predictions of muscle forces acting on the hip have been also used to improve estimates of bone remodeling stimulus.

  • Biophysics of the Generation of EMG Signals

    This chapter describes the basic concepts of generation and detection of EMG signals. Specific emphasis is devoted to the generation of muscle fiber action potentials at the fiber end plates, their propagation along the sarcolemma, and their extinction at the tendons. The chapter addresses the topics of crosstalk between nearby muscles and selectivity of the recording systems. It discusses the relationships between muscle force and the surface EMG. The EMG signal is generated by the electrical activity of the muscle fibers active during a contraction. The signal sources are the depolarizing and repolarizing zones of the muscle fibers. EMG signal features depend on a number of anatomical, physical, and detection system parameters. Considering all the factors related to the volume conductor and the signal sources that influence the characteristics of the EMG signal, a reliable relation between EMG amplitude and force needs a subject specific and condition specific calibration.

  • Single-Channel Techniques for Information Extraction from the Surface EMG Signal

    This chapter describes some of the most commonly used techniques for processing single-channel surface electromyographic (sEMG) signals. The single-channel techniques address the interference pattern that results from the simultaneous activation of many motor units (MUs). The chapter reviews spectral estimation and traditional stochastic models applicable to the electromyographic (EMG) signal. These models are used to develop, interpret, and test most of the signal processing techniques. EMG amplitude estimates have been assessed via a common application: the use of surface EMG to estimate joint torques. The chapter explores the basic body of knowledge concerning EMG spectral analysis and how physiological parameters are reflected by surface EMG power spectra. It further focuses on the theoretical basis for the assessment of muscle fatigue during high-intensity isometric constant force contractions since this assessment is by far the most prevalent application of surface EMG spectral analysis.

  • Conclusions and Future Work

    This chapter presents the conclusions described in the book related to the fusion of hard control strategies such as proportional integral‐derivative (PID), optimal, adaptive, and soft control strategies such as adaptive neuro‐fuzzy inference system (ANFIS), genetic algorithms (GA), particle swarm optimization (PSO), for a robotic or prosthetic hand. Chapter 2 of the book addressed the forward kinematics, inverse kinematics, and differential kinematics models of a serial n revolute‐joint planar two‐link thumb, and three‐link index finger. The fingertip (end‐effector) positions of each finger were derived by forward kinematics. Chapter 3 of the book described the dynamic equations of hand motion successfully derived via Lagrangian approach for two‐link thumb and three‐link fingers using the mathematical model of the actuator by using direct current (DC) motor and mechanical gears.
