Single fibre electromyography in central core disease.
Single fibre electromyography in the extensor digitorum communis muscle was studied in five patients with central core disease. The average number of muscle fibre action potentials belonging to the same motor unit was higher in patients than in healthy subjects of the same age. The increase in motor unit fibre density is consistent with increased terminal innervation ratio described in other pa...
متن کاملNeuromuscular 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 کاملSingle-fibre electromyography (SFEMG) at different firing rates in myasthenia with and without thymoma.
The single fibre EMG differences during motor axonal stimulation at different firing rates were studied in myasthenic patients: 15 with, and 15 without thymoma. 10 healthy volunteers were also examined. Conventional repetitive stimulation EMG as well as SFEMG during weak voluntary contraction and on 10 and 20Hz stimulation was performed in every patient. The mean jitter in the control group was...
متن کاملSingle fibre electromyography in multifocal motor neuropathy with persistent conduction blocks.
OBJECTIVE To study the process of denervation-reinnervation in multifocal motor neuropathy with persistent conduction blocks in clinically affected and unaffected muscles. METHOD Volitional single fibre electromyography (SFEMG) was performed in the extensor digitorum communis (EDC) of seven patients. The jitter, the fibre density, and the mean interpotential interval were determined. The resu...
متن کاملRegional curare for the reduction of the safety factor in human motor end-plates studied with single fibre electromyography.
A method employing six minutes of regional curarization with 0.5 mg D-tubocurarine and single fibre electromyographic measurements (SFEMG) was used in order to study the effect of an additional small dose of D-tubocurarine. The effect of the additional dose was most pronounced in terms of increased jitter, on motor end-plates with the initially highest jitter. The combination of regional curari...
