Zusammenfassung
Introduction: Multifocal motor neuropathy (MMN) is an immune-mediated demyelinating neuropathy, that is clinically characterised by slowly progressive, asymmetric weakness of the limbs. Electrophysiological examination typically shows conduction blocks in one or more peripheral nerves. However, even with the usage of high voltage transcutaneous cervical root stimulation, in most patients, the electrophysiological abnormalities are restricted to a few nerves. Compound velocity distribution (CVD) is a collision method with variable time points between the electric stimuli, allowing the calculation of the velocity…
