Crosstalk Removal in Stimulus-evoked Forearm Electromyography

Crosstalk in surface electromyography of the proximal forearm during gripping tasks.

Electromyographic (EMG) crosstalk was systematically analyzed to evaluate the magnitude of common signal present between electrode pairs around the forearm. Surface EMG was recorded and analyzed from seven electrode pairs placed circumferentially around the proximal forearm in six healthy individuals. The cross-correlation function was used to determine the amount of common signal, which was fo...

Experimentation and Structural Modeling of Stimulus-Evoked Electromyography in Muscles During Electrically-Elicited Fatigue Process

Electrode Placement in Surface Electromyography (sEMG) “Minimal Crosstalk Area” (MCA)

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 patt...

Sevoflurane affects evoked electromyography monitoring in cerebral palsy

BACKGROUND To explore the effect of sevoflurane inhalation anesthesia on evoked electromyography monitoring of spinal nerve root in children associated with cerebral palsy. METHODOLOGY Children with cerebral palsy (n=40) were selected and further divided into 1MAC (minimum alveolar concentration) sevoflurane group and 2MAC sevoflurane group. Following the induction of anesthesia, Nicolet Ende...

Stimulus-evoked synchronization in neuronal models

It is known that stimulus-evoked synchronization among neurons occurs in widely separated cortical regions. In this paper we test that how common, random but not deterministic inputs can synchronize groups of neurons with their parameters inside physiologically plausible regions. When a common, random input is presented, we .nd that a group of neurons—of integrate-and-.re or Hodgkin–Huxley mode...
