In addition, the electrodes used are available at a low cost and some are even disposable. First, the technique does not require a healthcare professional to insert the electrodes, which enables more widespread use in the research domain. sEMG has several advantages over the use of invasive electrodes. However, inserting electrodes is an invasive procedure and implanted electrodes cause patient discomfort during muscle movement sEMG was introduced to overcome these problems. ![]() When EMG was first developed, only intramuscular electrodes were used. In the latter technique, known as the surface electromyography (sEMG), the signal is the combined electrical activity created by all motor units. EMG signals can be detected directly using invasive electrodes placed in the muscle or as a superposition of signals gathered using electrodes applied at the surface of the skin. Finally, this paper provides a discussion on the suitability of the individual methods based on the type of contaminant(s) present in the signal and the specific requirements of the application.Įlectromyography (EMG) is a widely used method that records the electrical activity of muscles by measuring the electrical potential created when a muscle contracts (voluntarily or not). This includes subtraction methods used in the time domain, denoising methods performed after the signal decomposition and hybrid approaches that combine multiple methods. Specifically, we focus on methods which enable a full reconstruction of the EMG signal without loss of information. The aim of this paper is to review methods employed to reduce the contamination of single channel EMG signals. Even assuming best practices, the acquired signal may still contain contaminants. However, EMG signals can be contaminated by various types of noise, interference and artifacts, leading to potential data misinterpretation.
