Intramuscular EMG Decomposition Basing on Motor Unit Action Potentials Detection and Superposition Resolution
A novel electromyography (EMG) signal decomposition framework is presented for the thorough and precise analysis of intramuscular EMG signals. This framework first detects all of the active motor unit action potentials (MUAPs) and assigns single MUAP segments to their corresponding motor units. MUAP waveforms that are found to be superimposed are then resolved into their constituent single MUAP...
متن کاملUsing Emg Decomposition for Extraction and Visualization of Motor Unit Action Potentials
This paper presents a developed tool capable of decomposing electromyographic signals (EMG) named EMG Decomposition. The main aim of this software is to extract and to visualize motor unit action potentials (MUAPs) extracted from EMG signals during a muscular contraction. The identification and clustering of MUAPs that show similar features is most important for the definition of such cluster s...
متن کاملEmg Decomposition: a System for Extraction and Visualization of Motor Unit Action Potentials
This paper presents a developed tool capable of decomposing electromyographic signals (EMG) named EMG Decomposition. The main aim of this software is to extract and to visualize motor unit action potentials extracted from EMG signals during a muscular contraction. The results obtained from the tool have application in the study of the behavior of the central nervous system and in the diagnosis ...
متن کاملAnalysis of intramuscular electromyogram signals.
Intramuscular electromyographic (EMG) signals are detected with needles or wires inserted into muscles. With respect to non-invasive techniques, intramuscular electromyography has high selectivity for individual motor unit action potentials and is thus used to measure motor unit activity. Decomposition of intramuscular signals into individual motor unit action potentials consists in detection a...
متن کاملA simulation study for a surface EMG sensor that detects distinguishable motor unit action potentials.
An advanced volume conductor model was used to simulate the surface-detected motor unit action potentials (MUAPs) due to current sources located at different depths within the muscle tissue of the biceps brachii. Seven different spatial filters were investigated by linear summation of the monopolarly detected surface MUAPs on a square array of nine electrodes. The criterion of the relative ener...
