Introduction
In this study we report the diagnostic value of the near‐nerve needle sensory nerve conduction study (NNN‐SNCS) in sensory inflammatory demyelinating polyneuropathy (IDP) in which the routine nerve conduction study was normal or non‐diagnostic.
Methods
The NNN‐SNCS was performed to identify demyelination in the plantar nerves in 14 patients and in the median or ulnar nerve in 2 patients with sensory IDP.
Results
In 16 patients with sensory IDP, routine NCSs were either normal or non‐diagnostic for demyelination. Demyelination was identified by NNN‐SNCS by dispersion and/or slow nerve conduction velocity (NCV) below the demyelination marker. Immunotherapy was initiated in 11 patients, 10 of whom improved or remained stable.
Discussion
NNN‐SNCS played an essential role in identifying demyelinaton in 16 patients with sensory IDP, leading to proper treatment. Muscle Nerve 57: 414–418, 2018
