Neuromuscular transmission in myasthenia gravis studied with single fibre electromyography.
Patients with myasthenia gravis have been investigated with single fibre electromyography. In all myasthenic muscles recordings were obtained where there was an increase of the jitter and occasional blocking of different degree of single fibre action potentials. The jitter is the variability at consecutive discharges in the time interval between action potentials from two muscle fibres from the...
متن کاملA new surface electromyography analysis method to determine spread of muscle fiber conduction velocities.
Muscle fiber conduction velocity (MFCV) estimation from surface signals is widely used to study muscle function, e.g., in neuromuscular disease and in fatigue studies. However, most analysis methods do not yield information about the velocity distribution of the various motor unit action potentials. We have developed a new method-the interpeak latency method (IPL)-to calculate both the mean MFC...
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...
متن کاملHOW TO DO IT Diagnose myasthenia gravis
© 2002 Blackwell Science Ltd INTRODUCTION This ‘How to do it’ series presents a paradox. The aim is simple – an expert advises a relative novice on the best approach to a particular problem, in this case the confi rmation of a suspected diagnosis of myasthenia gravis. However, in reality the approaches of the expert and the novice are quite different. The expert subconsciously uses their enormo...
متن کاملa new type-ii fuzzy logic based controller for non-linear dynamical systems with application to 3-psp parallel robot
abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
