Reference values in concentric needle electrode studies.
A recommendation of considerable concern is that different cutoff limits be used ‘‘depending on the clinical purpose’’. The electromyographer must report the results objectively and distinguish clearly between the results of electrophysiologic testing and conclusions based on other factors. There should only be one cutoff value, but the ultimate interpretation should take into account clinical ...
متن کاملConcentric needle single fiber electromyography: normative jitter values on voluntary activated Extensor Digitorum Communis.
Single fiber electromyography (SFEMG) is the most sensitive clinical neurophysiological test for neuromuscular junction disorders, particularly myasthenia gravis. Normal values for jitter obtained with SFEMG electrode have been published, but there are few publications for concentric needle electrode (CNE). The aim of this study was to discuss the possibilities to analyse the jitter in CNE reco...

متن کاملReference values for jitter recorded by concentric needle electrodes in healthy controls: A multicenter study.
INTRODUCTION The aim of this study was to create reference values for jitter measured with concentric needle electrodes. METHODS Operators worldwide contributed recordings from orbicularis oculi (OO), frontalis (FR), and extensor digitorum (ED) muscles in healthy controls. Criteria for acceptable signal quality were agreed upon in advance. Fifteen or 20 recordings of acceptable quality from e...
متن کاملConcentric needle single fiber electromyography: comparative jitter on voluntary-activated and stimulated Extensor Digitorum Communis.
OBJECTIVE To compare the jitter values in voluntarily activated (v-CNE) and stimulated (s-CNE) techniques for Extensor Digitorum Communis muscle using a disposable concentric needle electrode (CNE). Quantifying jitter using a CNE in conjunction with a stimulated technique has not been reported previously. METHODS Forty-one normal subjects were studied, 15 male and 26 female with a mean age of...
