چکیده

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 action potential and magnetic field at the abdominal surface. We introduce a simplified geometry for the problem and solve our model in this domain using finite element method (FEM). Numerical examples are provided to illustrate our analytical results. Keywords— Magentomyogram, electromyogram. transmembrane potential modeling.

Modeling Magnetomyograms of Uterine Contractions during Pregnancy Using a Multiscale Forward Electromagnetic Approach

Understanding the mechanisms of uterine contractions during pregnancy is especially important in predicting the onset of labor and thus in forecasting preterm deliveries. Preterm birth can cause serious health problems in newborns, as well as large financial burdens to society. Various techniques such as electromyography (EMG) and magnetomyography (MMG) have been developed to quantify uterine c...

Multiscale forward electromagnetic model of uterine contractions during pregnancy

BACKGROUND Analyzing and monitoring uterine contractions during pregnancy is relevant to the field of reproductive health assessment. Its clinical importance is grounded in the need to reliably predict the onset of labor at term and pre-term. Preterm births can cause health problems or even be fatal for the fetus. Currently, there are no objective methods for consistently predicting the onset o...

معرفی روش استفاده از سیگنال مکانومیوگرام در ارزیابی عملکرد عضلات

  Background and aims   Recordings of electrical activity in the muscle and surface electromyography (EMG) have been widely used in the field of applied physiology. In parallel to  recording of the EMG, the detectable low-frequency vibration signal generated by the skeletal  muscle has been known and well documented. As the nature of the signal has been progressively   revealed, the term of mec...

MMG and EMG responses during fatiguing isokinetic muscle contractions at different velocities.

The purpose of this study was to determine mechanomyographic (MMG) and electromyographic (EMG) responses of the superficial quadriceps muscles during repeated isokinetic contractions in order to provide information about motor control strategies during such activity, and to assess uniformity in mechanical activity (MMG) between the investigated muscles. Ten adults performed 50 maximal concentri...

Effect of sex on torque, recovery, EMG, and MMG responses to fatigue

OBJECTIVE The purpose of the present investigation was to examine the effect of sex on maximal voluntary isometric contraction (MVIC) torque and the EMG and MMG responses as a result of fatiguing, intermittent, submaximal (65% of MVIC), isometric elbow flexion muscle contractions. METHODS Eighteen men and women performed MVIC trials before (pretest), after (posttest), and 5-min after (5-min r...
