چکیده

Correspondence to: Professor Kerry R Mills, Department of Clinical Neurophysiology, King’s College Hospital, Denmark Hill, London SE5 9RS, UK; [email protected] _________________________ E lectromyography (EMG), the recording of electrical activity in muscle, should be regarded as an extension of the clinical examination. It can distinguish myopathic from neurogenic muscle wasting and weakness. It can detect abnormalities such as chronic denervation or fasciculations in clinically normal muscle. It can, by determining the distribution of neurogenic abnormalities, differentiate focal nerve, plexus, or radicular pathology; and it can provide supportive evidence of the pathophysiology of peripheral neuropathy, either axonal degeneration or demyelination. EMG is an obligatory investigation in motor neurone disease to demonstrate the widespread denervation and fasciculation required for secure diagnosis.

The Muscle Sensor for on-site neuroscience lectures to pave the way for a better understanding of brain–machine-interface research

Neuroscience is an expanding field of science to investigate enigmas of brain and human body function. However, the majority of the public have never had the chance to learn the basics of neuroscience and new knowledge from advanced neuroscience research through hands-on experience. Here, we report that we produced the Muscle Sensor, a simplified electromyography, to promote educational underst...

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...

Modulatory Effect of Acetaminophen-Oxicodon and Lorazepam on the Pain Elicited by Needling in Electromyography

Introduction: Pain is one of the complications of electromyography. The present study was designed to evaluate the effects of acetaminophen-oxycodone and lorazepam on the pain caused by needling in electromyography. Materials and Methods: In this clinical study, 150 patients were divided into three groups (receiving lorazepam, acetaminophen and placebo). Pain was measured by visual analogue sca...

The effect of focus of attention on electromyography activity of the rectus abdominus muscle in vertical jump

Various studies have shown that the external focus of attention is better than the internal focus of attention. But, so far no study has been investigated the level of electrical activity of the rectus abdominus muscle as a trunk stabilizer muscle. Therefore, the purpose of this study was to investigate the effect of focus of attention on electromyography activity of the rectus abdominus muscle...
