Diagnostic characteristics of nerve conduction study parameters for vasculitic neuropathy.

ABSTRACT:

Introduction/aims

In vasculitic neuropathy (VN), a 50% side-to-side difference in the amplitude of compound muscle action potentials and sensory nerve action potentials is considered meaningful, but unequivocal evidence is lacking. The aim of this study is to characterize electrodiagnostic features that best distinguish VN from other axonal polyneuropathies.

Methods

We conducted a case-control study between January 2000 and April 2021. We reviewed the records of patients with VN who had bilateral nerve conduction studies (NCS) and evaluated different electrodiagnostic models to help distinguish VN from non-inflammatory axonal polyneuropathies.

Results

We identified 82 cases, and 174 controls with non-inflammatory axonal neuropathies. The amplitude percent difference Z
