Objectives: To assess the diagnostic and prognostic role of electromyography (EMG) of the external anal sphincter and pelvic floor muscles in children born with anorectal anomalies. Also, we tried to assess the role of electric stimulation to the sphincter muscles when applied pre and/or postoperatively in the control of fecal incontinence in those children. Methods: Eighty children with congen...

Metabolic rates can increase 21 times above resting levels during cycling with the majority attributed to muscular contractions. Metabolic estimates attained through gas exchange parameters are limited by the respiration rate and time delay with respect to these contractions. In contrast surface electromyography (EMG) contains instantaneous muscle contraction information at higher temporal reso...

Background The paucity of easy-to-use, reliable objective neuromuscular monitors is an obstacle to universal adoption routine monitoring. Electromyography (EMG) has been proposed as the optimal monitoring technology since it addresses several acceleromyography limitations. This clinical study compared simultaneous responses recorded from induction block until recovery using acceleromyography-ba...

This paper considers the application of Blind Source Separation (BSS) to electromyographic (EMG) data as an approach to isolating individual motor unit potentials (MUPs). BSS was applied both to needle EMG (nEMG) and surface EMG (sEMG), and experimental results were obtained that demonstrate the effectiveness of this approach. BSS is proposed as a technique to be incorporated into EMG methodolo...

First published December 5, 2003; 10.1152/ japplphysiol.00687.2003.—Intramuscular pressure (IMP) and electromyography (EMG) mirror muscle force in the nonfatigued muscle during static...

Sensorimotor control dysfunction or dyskinesia is a hallmark of neuromuscular impairment in children with cerebral palsy (CP), and is often implicated in reaching and grasping deficiencies due to a neuromuscular imbalance between the triceps and biceps. To mitigate such muscle imbalances, an innovative electromyography (EMG)-virtual reality (VR) biofeedback system were designed to provide accur...

Background: Electromyography (EMG) signal processing and Muscle Onset Latency (MOL) are widely used in rehabilitation sciences and nerve conduction studies. The majority of existing software packages provided for estimating MOL via analyzing EMG signal are computerized, desktop based and not portable; therefore, experiments and signal analyzes using them should be completed locally. Moreover, a...
