Some of these studies however, have utilized conventional processors to obtain the EMG amplitudes...
EMG峰值/均值、iEMG(integrated EMG),它可以是整段信号的积分,固定时间段的(窗口)积分或者到一个阈值的积分、EMG的RMS、协同收缩比(co-contraction,Leweket al., 2004)、振幅概率密度(Amplitude Probability Distribution Function,在人体功效学常用) etc. 频域分析 与时域相对应的分析,信号频域也是肌电分析常用的方法...
The present study aimed to evaluate the effect of a resistance training program based on the electromyographic fatigue threshold (EMG FT, defined as the highest exercise intensity performed without EMG alterations), on the EMG amplitude (root mean square, RMS) and frequency (median frequency, MF)...
surfa.ce EMG is frequently used as the control input to myoelectric prostheses, as a measure of muscular effort, and has also been investigated as an indicator of muscle force This paper will review the methods which are used to estimate the EMG amplitude from recordings of the EMG waveform....
Surface electromyographic (EMG) amplitude from the upper trapezius muscle is widely used as a measure of shoulder-neck load in ergonomic studies. A variety of methods for normalizing EMG amplitude from the upper trapezius (EMGamp(ut)) have been presented in the literature. This impedes meta-analy...
Whitening decorrelates the EMG signal and has been shown to be advantageous in other EMG applications including EMG amplitude estimation and EMG-force ... Lukai,Liu,A Edward,... - 《IEEE Transactions on Neural Systems & Rehabilitation Engineering A Publication of the IEEE Engineering in Medicine...
The attainment of an appropriate level of EMG amplitude seems to be controlled by (a) timing muscle activation at a latency timed from the expected instant of foot contact and (b) varying the rate at which EMG builds up. 展开 关键词: intense running exercises oxygen uptake kinetics energy ...
This analysis, called the Amplitude Distribution Analysis, is a computer program that analyses the distribution density of voltage for all the digitalized data of some signals. In this article we explain this analysis and how we analyzed three kinds of standard signals(a square wave, a chopping ...
Automated EMG onset detection was performed with a previously proposed algorithm35. An occasional detection of EMG bursts prior to the main activation was accepted because an objective increase of EMG amplitude may elicit muscle motion and may explain the detection of early muscle motion. Visual onset...
The other strategy consists of performing measurements at a constant walking speed and BWS, an approach successfully pioneered by Dietz et al.8,9 As training evolved, they showed clear increases in EMG amplitude of several leg muscles during walking on a treadmill at a constant speed. In the ...
