Nowadays, analysis of electromyography (EMG) signal using wavelet transform is one of the most powerful signal processing tools. It is widely used in the EMG recognition system. In this study, we have investigated usefulness of extraction of the EMG features from multiple-level wavelet decomposition of the EMG signal. Different levels of various mother wavelets were used to obtain the useful re...

While many approaches have been proposed to identify the signal onset in EMG recordings, there is no standardized method for performing this task. Here, we propose to use a change-point detection procedure based on singular spectrum analysis to determine the onset of EMG signals. This method is suitable for automated real-time implementation, can be applied directly to the raw signal, and does ...

40 Fingertip force control requires fine coordination of multiple hand muscles within 41 and across the digits. While the modulation of neural drive to hand muscles as a function 42 of force has been extensively studied, much less is known about the effects of fatigue on 43 the coordination of simultaneously active hand muscles. We asked eight subjects to 44 perform a fatiguing contraction by g...

Rectification of surface EMG before spectral analysis is a well-established preprocessing method used in the detection of motor unit firing patterns. A number of recent studies have called into question the need for rectification before spectral analysis, pointing out that there is no supporting experimental evidence to justify rectification. We present an analysis of 190 records from 13 subjec...

Background Fatigue is an important factor for muscle strengthening in rehabilitation medicine. Frequency analysis has been regarded as the gold standard fatigue assessment surface electromyography (EMG). However, there are no experiments quantifying with grouped discharge (GD), which one of historical phenomena observed patients having fatigue, by using high sampling rate recording EMG. Objecti...

Head orientation prediction is one of the solutions to reduce end-to-end latency on Virtual Reality (VR) systems and important since it can alleviate negative effects like motion sickness. This study compared head models from two different electromyography (EMG) systems: surface EMG (sEMG) High-Density (HD-EMG). The deep learning method was used train model, results showed that model with input...

As a part of EMG-net project, researchers at the Slovak University of Technology developed a software tool for collection and management of electromyography (EMG) examination cases called EMMA. They concentrated on data representation, which is a crucial task in such data intensive area as the EMG examination. The proposed data model serves as a basis for a multifunctional platform for EMG stud...
