title: [Neurophysiology of Vasculitic Peripheral Neuropathy].
abstract: Nerve conduction studies (NCSs) are essential to the work up of peripheral neuropathy. NCSs are useful in vasculitic neuropathy because they can serve as a guide in the nerve biopsy, as well as detect asymptomatic vasculitic neuropathy. NCSs characteristically show axonal loss of motor and sensory fibers with asymmetric or non-length-dependent patterns. Occasionally, conduction block (CB) or pseudo CB are observed. Pseudo CB is appears in the acute phase before Wallerian degeneration has developed distal to the infarcted nerve, and then disappears within two weeks.
