Adaptive signal processing of surface electromyogram signals
Electromyography is the study of muscle function through the electrical signals from the muscles. In surface electromyography the electrical signal is detected on the skin. The signal arises from ion exchanges across the muscle fibres’ membranes. The ion exchange in a motor unit, which is the smallest unit of excitation, produces a waveform that is called an action potential (AP). When a sustai...
متن کاملEstimating motor unit discharge patterns from high-density surface electromyogram.
OBJECTIVE We systematically tested the capability of the Convolution Kernel Compensation (CKC) method to identify motor unit (MU) discharge patterns from the simulated and experimental surface electromyogram (sEMG) during low-force contractions. METHODS sEMG was detected with a grid of 13 x 5 electrodes. In simulated signals with 20 dB signal-to-noise ratio, 11+/-3 out of 63 concurrently acti...
متن کاملSpeech Synthesis from Surface Electromyogram Signals
Although speech is the most natural means for communication among humans, there are situations in which speech is impossible or inappropriate. Examples include people with vocal cord damage, underwater communications or in noisy environments. To address some of the limitations of speech communication, nonacoustic communication systems using surface electromyogram signals have been proposed. How...
متن کاملEstimation of a Cubital Joint Torque Using Surface Electromyogram Signals
This work focuses on the development of a wearable power-assisted orthosis for nursing care as a health care device to reduce the physical burden on carers. The most important aspect of developing a power-assisted orthosis is that it reflects the orthosis wearer’s intentions, coordinating with the wearer’s voluntary movements. To realize this intention, our work focuses on a torque around a cub...
متن کاملTowards a Hand Gestures Recognition Using Weak and a Single-channel Surface Emg Signals
This article presents a method to obtain a myoelectric control system for hand prosthesis with individual fingers, wrist flexion/extension and grasp movements, based on weak surface electromyogram (sEMG) recorded from the forearm, both able-bodied and amputees. This study aims to a reduced-channel scheme (a single sEMG channel) for hand patterns discrimination. A combination of commonly used fe...
