Estimation of on-off timing of human skeletal muscles during movement is an ongoing issue in surface electromyography (sEMG) signal processing for relevant clinical applications. Widely used single threshold methods still rely on the experience of the operator to manually establish a threshold level. In this paper, a novel approach to address this issue is presented. Based on the generalized likelihood ratio test, the maximum likelihood (ML) method is improved with an adaptive threshold…

Muscle activity detection in pathological, weak and noisy myoelectric signals

An approach based on the continuous wavelet transform to detect the muscular activity, in muscle with low amplitude and low SNR, shows satisfactory performances especially when proper threshold values are chosen and could be used to study pathological, weak and noisy myoelectric signals.

Detection of Muscle Activities in the sEMG Signal by Using Frequency Features and Adaptive Decision Threshold

An amplitude-independent algorithm had been developed with an adaptive decision threshold; the algorithm employed only frequency features of the sEMG signal to detect muscle activities and revealed an improved performance regarding the resistance against false alarms.

Event Detection of Muscle Activation Using an Electromyogram

The experimental results indicated that the estimated errors for both the onset and offset detection are lower than those obtained using two of the conventional methods.


An automatic and simple algorithm for the real-time onset time detection of surface electromyography signals using a simple square integral (SSI) as the smoothing-threshold equation with the given sEMG signals is presented.

Robust Muscle Activity Onset Detection Using an Unsupervised Electromyogram Learning Framework

This study presents an unsupervised EMG learning framework based on a sequential Gaussian mixture model (GMM) to detect muscle activity onsets and demonstrated robust performance for low and changing signal to noise ratios in a dynamic environment.

EMG Onset Detection Based on Teager-Kaiser Energy Operator and Morphological Close Operation

Two schemes are utilizes, Teager-Kaise Engergy TKE operator and Morphological Close Operation MCO, to improve the accuracy of the onset/offset detection of EMG activities to achieve precise onset detection absolute error under a variety of signal-to-noise ratios SNR of the biomedical signal.

An amplitude independent muscle activity detection algorithm based on adaptive zero crossing technique and mean instantaneous frequency of the sEMG signal

A new algorithm has been developed to detect the presence of muscle activities in weak and noisy sEMG signals that have low signal to noise ratio and the Adaptive Zero Crossing (AZC) technique is used to minimize false alarms and enhances the detection process.

Unsupervised Stochastic Strategies for Robust Detection of Muscle Activation Onsets in Surface Electromyogram

Two unsupervised statistical approaches are posited— scree-plot elbow detection (SPE) heavily relying on the threshold choice and the more robust profile likelihood maximization (PLM) that obviates parameter tuning—for accurately detecting muscle activation onsets (MAOs).

Determination of an Optimal Threshold Value for Muscle Activity Detection in EMG Analysis.

Evaluation of the data had clearly shown that it is important to select proper threshold values for correct EMG signal analyses, and α priori accepted threshold value may cause erroneous results in EMG analysis.
