Ultrasound-Guided Near-Nerve Needle Recording in Sensory Conduction Study of the Superficial Fibular Nerve.

ABSTRACT:

Introduction/aims

The sensory nerve action potential (SNAP) of the superficial fibular nerve (SFN) is occasionally small and difficult to obtain using conventional surface recording (SR) or near-nerve needle recording. This study aimed to demonstrate a novel method of sensory conduction study of the SFN using ultrasound-guided near-nerve needle recording (US-NNNR) to obtain larger amplitude recordings.

Methods

Twenty healthy volunteers (40 legs) were analyzed. In the conventional sensory conduction study using SR, we stimulated the nerve on the lateral aspect of the mid lower leg. The SNAPs of the medial dorsal cutaneous nerve (MDCN) and intermediate dorsal cutaneous nerve (IDCN) of the SFN were recorded at the ankle. In the US-NNNR, the SFN was scanned on the lateral aspect
