摘要

目的:腓肠神经是周围神经病变电诊断中检测最多的下肢感觉神经。本研究提出了参考值腓肠神经传导研究(NCS)从阿尔及利亚人口的显著样本。方法:在AANEM-NDTF的基础上,对健康受试者的右侧腓肠NCS进行前瞻性研究。因此,确定了每个电生理参数分布的性质。分别采用第5百分位和第95百分位计算下限和上限,并对感觉神经动作电位(SNAP)振幅分布进行对数变换。结果:入选受试者115人,年龄在20 ~ 60岁之间,其中女性58人,男性57人。与感觉神经传导速度(SNCV)不同,SNAP振幅的分布不是高斯分布。采用第5百分位法SNAP振幅下限为7.70µV,对数变换后采用标准差法SNAP振幅下限为6.80µV。SNCV的下限为43 m/s。SNAP的振幅在女性中更大,并随着年龄、身高和BMI的增加而降低。结论:本研究发现的数值与已发表的文献相当。根据最近几位作者的建议,使用百分位数来确定参考值可能更合适。

Sural nerve conduction study: Reference values in the Algerian population
Objectives: The sural nerve is the most tested sensory nerve in the lower extremities in the electrodiagnostic assessment of peripheral neuropathies. This study presents the reference values of the sural nerve conduction study (NCS) from a significant sample of the Algerian population. Methods: This is a prospective study of right sural NCS in healthy subjects based on the later recommendations of AANEM-NDTF. The nature of the distribution of each electrophysiological parameter was therefore determined. The lower and upper limits were calculated by using the 5th and 95th percentiles respectively and a logarithmic transformation was performed for Sensory Nerve Action Potential (SNAP) amplitude distribution. Results: 115 subjects aged between 20 and 60 years were selected, including 58 women and 57 men. Unlike Sensory Nerve Conduction Velocity (SNCV), the distribution of SNAP amplitude is not Gaussian. The lower limit of SNAP amplitude was 7.70 µV when using the 5th percentile and 6.80 µV by using the Standard Deviation (SD) method after log transformation. Similarly, the lower limit of SNCV was 43 m/s. The SNAP amplitude was greater in women and decreased with age, height and BMI. Conclusion: The values found in this study are comparable to those published in the literature. It may be more appropriate to determine the reference values using percentiles as recently recommended by several authors.
