Wireless Surface Electromyography
2017Surface Electromyography (sEMG) is used in the evaluation of muscle activation patterns during body movements. Artefacts in sEMG-signals and analysis are caused by the movements of the cables between the sensor and electrode. Hence, there already exist some pre-amplified and wireless sEMG electrodes.

Surface electrodes in perineal electromyography
Urology, 1988In 40 elderly male patients undergoing multiple urodynamic evaluations, surface electrodes were used for recording electromyographic (EMG) activity of pelvic sphincter muscles; placement site was the external anal sphincter. The measured wave form was displayed as an analog plot. Different types of surface electrodes were evaluated in selected patients.

Contactless sensors for Surface Electromyography
2006 International Conference of the IEEE Engineering in Medicine and Biology Society, 2006Muscle activity can be monitored by measuring the surface electromyography (SEMG) signal at the surface of the body. The SEMG signal is a combination of several activation signals sent through the muscle fibers triggering the contraction of the muscle. SEMG enables to access those signals non-invasively.

Surface stimulation single‐fiber electromyography
Muscle & Nerve, 1998Stimulation single-fiber electromyography (S-SFEMG) is an alternative method to SFEMG during voluntary contraction (VC-SFEMG). S-SFEMG is preferred to VC-SFEMG in uncooperating patients, children, and patients having severe weakness. Surface stimulation is a viable alternative to needle stimulation in S-SFEMG.

Detection of the Anaerobic Threshold by Surface Electromyography
2006 International Conference of the IEEE Engineering in Medicine and Biology Society, 2006This work aims at presenting a method for automatic detection of the anaerobic thresholds by surface electromyography (RMS-slope) and compare with respective values identified by the analysis of ventilatory gas exchange. Thirteen healthy adults were submitted to a single maximal oxygen uptake test, being monitored the ventilatory parameters V(O2), V ...

The History of Surface Electromyography
Applied Psychophysiology and Biofeedback, 2003The history of muscle pain and dysfunction is viewed through the lens of a four factor theory of histologic (tissue related) issues, psychologic (emotional) issues, sensory motor (movement) issues, and biomechanical (postural) issues. The historical antecedents of surface electromyography are reviewed.

Wavelet analysis of surface electromyography signals
The 26th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2005A number of digital signal processing (DSP) techniques are being applied to surface electromyography (SEMG) signals to extract detailed features of the signal. Fast Fourier transform (FFT) is one of the most common methods for analyzing the signal whether it is filtered or not.

Biomechanics: Surface electromyography prosthesis control
2012 5th International Conference on BioMedical Engineering and Informatics, 2012This paper provides a method to control a robotic arm by analyzing Electromyogram (EMG) collected from surface of the forearm. The electrodes are strategically placed on top of a particular muscle to harvest its myoelectric signals generated by physiological variations associated with muscular activities such as contraction and retraction.

Surface electromyography analysis for variable gait
Gait & Posture, 2003The surface electromyographic (SEMG) signal obtained during gait is often presented as the SEMG profile, the average SEMG activation pattern during one gait cycle. A disadvantage of this method is that it omits the step-to-step variability of the timing of the muscle activation patterns that might be relevant information as a performance measure of ...

Surface Electromyography for Noninvasive Characterization of Muscle
Exercise and Sport Sciences Reviews, 2001Surface electromyography for noninvasive characterization of muscle. Exerc. Sport Sci. Rev., Vol. 29, No. 1, pp 20-25, 2001. Linear electrode arrays are used for noninvasive muscle characterization to study individual motor unit properties and the myoelectric manifestations of muscle fatigue during sustained contractions.
