Do A-waves help predict intravenous immunoglobulin response in multifocal motor neuropathy without block?
Are there electrophysiological findings that predict response to intravenous immunoglobulin (IVIg) in patients with lower motor neuron (LMN) syndromes without multifocal conduction block (MCB)? ⋯ "Abnormal A-waves" may signal IVIg-responsive LMN syndromes even if conduction block is absent.
