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

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
INTRODUCTION/
aimsThe 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.
methodsTwenty 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 of the mid lower leg and a needle electrode was inserted with an out-of-plane approach < 1 mm from the SFN. Through the needle electrode, we recorded the SNAPs evoked by the stimulation of the MDCN or IDCN at the ankle. The SNAP amplitudes were compared between the SR and US-NNNR using the Wilcoxon signed-rank test.
resultsThe SNAP amplitude was significantly larger with US-NNNR than with SR for both the MDCN (p < 0.001) and the IDCN (p < 0.001). DISCUSSION: US-NNNR in sensory conduction study of the SFN produced a larger SNAP amplitude than SR. The larger SNAP observed using US-NNNR may aid in the diagnosis of disorders involving the SFN.
