Forward Modeling of Uterine EMG and MMG Contractions
We develop a forward model for uterine electromyogram (EMG) and magnetomyogram (MMG) contractions. Our model aims to describe the electrophysiological aspects of uterine contractions during pregnancy at both the cellular and organ levels. In particular, we apply a bidomain approach for modeling the propagation of the myometrium transmembrane potential on the uterus and use it to compute the act...
متن کاملAutomatic Identification of Motion Artifacts in EHG Recording for Robust Analysis of Uterine Contractions
Electrohysterography (EHG) is a noninvasive technique for monitoring uterine electrical activity. However, the presence of artifacts in the EHG signal may give rise to erroneous interpretations and make it difficult to extract useful information from these recordings. The aim of this work was to develop an automatic system of segmenting EHG recordings that distinguishes between uterine contract...
متن کاملInter-electrode spacing of surface EMG sensors: reduction of crosstalk contamination during voluntary contractions.
We investigated the influence of inter-electrode spacing on the degree of crosstalk contamination in surface electromyographic (sEMG) signals in the tibialis anterior (target muscle), generated by the triceps surae (crosstalk muscle), using bar and disk electrode arrays. The degree of crosstalk contamination was assessed for voluntary constant-force isometric contractions and for dynamic contra...
متن کاملMacro EMG, a new recording technique.
A new electromyographic technique for the study of the motor unit is described. A modified single fibre EMG electrode is used. The electrical activity obtained by the electrode shaft during voluntary muscle contraction is averaged after triggering from a single muscle fibre action potential and the contribution from one motor unit is thus extracted. This "Macro EMG" signal gives information abo...
متن کاملA Method for Signal Quality Assessment during Ambulatory EMG Recording
Biopotential signal recording is often affected by noise during recording. There is a large body of literature on noise removal techniques for every class of biopotential signals. However, obtaining clean recording is preferable to cleaning a noisy recording. An instantaneous quality measure of the signal to noise ratio during recording would be invaluable in correcting a defective recording si...
