One of the defining electrophysiological characteristics of multifocal motor neuropathy (MMN) is focal motor nerve conduction block. We have noted occasional patients with typical clinical features of MMN in whom there is no demonstrable conduction block. Upon review of 5 such cases, we conclude that otherwise typical MMN may present without overt conduction block. This subset of patients does not otherwise differ from patients with MMN in whom this hallmark electrodiagnostic feature is present.
