Introduction

The diagnosis of Hereditary Neuropathy with Liability to Pressure Palsy (HNPP) is frequently missed or delayed because of its clinical and electrophysiological heterogeneity. Nonetheless, electrophysiological criteria were published 15 years ago. Our aim was to highlight the Terminal Latency Index (TLI) disorders by describing the electrophysiological characteristics in patients with HNPP.
