Modulation of EMG-EMG Coherence in a Choice Stepping Task
The voluntary step execution task is a popular measure for identifying fall risks among elderly individuals in the community setting because most falls have been reported to occur during movement. However, the neurophysiological functions during this movement are not entirely understood. Here, we used electromyography (EMG) to explore the relationship between EMG-EMG coherence, which reflects c...
متن کاملEMG-EMG coherence during three-digit grasping
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...
متن کاملEvaluation of jaw and neck muscle activities while chewing using EMG-EMG transfer function and EMG-EMG coherence function analyses in healthy subjects
This study aims to quantitatively clarify the physiological features in rhythmically coordinated jaw and neck muscle EMG activities while chewing gum using EMG-EMG transfer function and EMG-EMG coherence function analyses in 20 healthy subjects. The chewing side masseter muscle EMG signal was used as the reference signal, while the other jaw (non-chewing side masseter muscle, bilateral anterior...

متن کاملEMG Controlled Hand Prosthesis: EMG Classification System
Since the 1970s, electromyographic control of a prosthetic device has been attempted in a number of different ways. It was only until recently, that the classification of electromyographic signals was possible through the use of neural networks. With the advent of more advanced techniques like support vector machines this type of control is becoming more realistic. This would initiate a great s...
