Electrode Placement in Surface Electromyography (sEMG) “Minimal Crosstalk Area” (MCA)
نویسندگان
چکیده
This paper is an introduction to a workshop on electrodes location and specific exercises. Selectivity of EMG electrodes depends on their interspacing, their conductive area and axis direction with respect to the direction of the underlying muscular fibres. Minimal cross talk area (MCA) helps to limit or avoid crosstalk from neighbouring muscles. We present examples of MCA and typical sEMG patterns during specific exercises.

Review of surface electrode placement for recording electromyography signals
Background: Surface Electromyography (SEMG) signal has used in monitoring muscle activities. It has been widely applied in many areas, such as body member prosthesis, noise cancellation for braincomputer interface, and robotics. The SEMG acquisition method for collecting the signal with low-noise has extensively investigated in the last decade. The objective of this study is to review the recen...
متن کاملNormalised Mutual Information of High-Density Surface Electromyography during Muscle Fatigue
This study has developed a technique for identifying the presence of muscle fatigue based on the spatial changes of the normalised mutual information (NMI) between multiple high density surface electromyography (HD-sEMG) channels. Muscle fatigue in the tibialis anterior (TA) during isometric contractions at 40% and 80% maximum voluntary contraction levels was investigated in ten healthy partici...
متن کاملTechnical Aspects of Surface Electromyography for Clinicians
Surface electromyography (sEMG) is a measure of the electrical potential present on the skin in consequence of a muscle contraction. This voltage is detected by electrodes placed on the skin. Under certain limitations, when a proper protocol for electrode placement is used, the voltage measured on the skin can be related to the activity of a single specific muscle. The signal is represented as ...
متن کاملSpatial variability in cortex-muscle coherence investigated with magnetoencephalography and high-density surface electromyography.
Cortex-muscle coherence (CMC) reflects coupling between magnetoencephalography (MEG) and surface electromyography (sEMG), being strongest during isometric contraction but absent, for unknown reasons, in some individuals. We used a novel nonmagnetic high-density sEMG (HD-sEMG) electrode grid (36 mm × 12 mm; 60 electrodes separated by 3 mm) to study effects of sEMG recording site, electrode deriv...
