FastICA peel-off for ECG interference removal from surface EMG
BACKGROUND Multi-channel recording of surface electromyographyic (EMG) signals is very likely to be contaminated by electrocardiographic (ECG) interference, specifically when the surface electrode is placed on muscles close to the heart. METHODS A novel fast independent component analysis (FastICA) based peel-off method is presented to remove ECG interference contaminating multi-channel surfa...
متن کاملProgressive FastICA Peel-Off and Convolution Kernel Compensation Demonstrate High Agreement for High Density Surface EMG Decomposition
Decomposition of electromyograms (EMG) is a key approach to investigating motor unit plasticity. Various signal processing techniques have been developed for high density surface EMG decomposition, among which the convolution kernel compensation (CKC) has achieved high decomposition yield with extensive validation. Very recently, a progressive FastICA peel-off (PFP) framework has also been deve...
متن کاملSurface EMG decomposition requires an appropriate validation.
TO THE EDITOR: A major constraint in the analysis of motor unit activity in humans is that relatively few active motor units can be detected concurrently due to the high selectivity of needle electrodes commonly used for electromyographic (EMG) recordings. Furthermore, the accurate decomposition of intramuscular EMG signals is usually not possible at high muscle forces due to the many motor uni...
متن کاملContralateral muscle activity and fatigue in the human first dorsal interosseous muscle.
During effortful unilateral contractions, muscle activation is not limited to the target muscles but activity is also observed in contralateral muscles. The amount of this associated activity is depressed in a fatigued muscle, even after correction for fatigue-related changes in maximal force. In the present experiments, we aimed to compare fatigue-related changes in associated activity vs. par...
متن کاملA study of fatiguing isometric contractions of the human first dorsal interosseous muscle.
Surface e lec t romyogram (EMG) f rom musc les undergoing sus ta ined i somet r ic voluntary contractions has been well studied. Power spect ra l analys is of the myoelect r ic signals so obtained, characteristically shows a t ime dependant sh i f t of the mean power f requency to lower f requenc ies , as the contraction proceeds (1). Such a compression of the EMG power spec t rum to lower freq...
