The electroneurograms of the tibial and median nerve in children with arthrogryposis have been performed; excitability curves which characterizes the function of the nerves were recorded. Afferent conduction velocity in 30 examined nerves showed statistically significant slowing down. An amplitude of evoked potentials in the tibial and median nerves was decreased but the difference compared to the control group was not statistically significant. Histograms based on electroneurography indicate existence of two groups of results, that might reflect neurogenic and/or myogenic origin of arthrogryposis. Excitability curve has been moved upwards and to the right in one point only, characterizing the tibial nerve function; in 5 remaining points the differences with controls were not significant. All-over results indicate subclinical afferentation impairment within lower extremities in children with arthrogryposis.
已对先天性多发性关节挛缩症患儿的胫神经和正中神经进行了神经电图检查；记录了表征神经功能的兴奋性曲线。在30条被检查的神经中，传入神经传导速度显示出统计学上的显著减慢。胫神经和正中神经诱发电位的幅度降低，但与对照组相比差异无统计学意义。基于神经电图的直方图表明存在两组结果，这可能反映了先天性多发性关节挛缩症的神经源性和/或肌源性起源。兴奋性曲线仅在一个点向上和向右移动，表征胫神经功能；在其余5个点与对照组的差异不显著。总体结果表明先天性多发性关节挛缩症患儿下肢存在亚临床传入功能障碍。
