Abstract

Clinical, electromyography (EMG) and nerve conduction velocity (NCV) features of 32 cases with peroneal muscular atrophy (PMA) are reported. Twenty of the cases showed remarkably slow NCV: median SNCV (Fing 1-W) X = 21.0 m/s, (Fing 3-W) X = 22.7 m/s, motor latency (ML) X = 7.3 ms; tibial SNCV (hallux-ankle) X = 22.2 m/s and ML = X = 8.1 ms, which were consistent with Type 1 PMA. Twelve cases showed normal or moderately slow NCV: median SNCV (Fing 1-W) X = 41.9 m/s, (Fing 3-W) X = 47.0 m/s and ML X = 3.2 ms; tibial SNCV (halluxankle) X = 32.5 m/s and ML X = 4.8 ms which were consistent with Type 2 PMA. The difference between these two groups was very significant (P less than 0.01). Sural nerve biopsy performed in 6 cases showed that 5 corresponded with NCV classification. We conclude that careful NCV examination is necessary for classification of PMA.

摘要

报告了32例腓骨肌萎缩症（PMA）患者的临床、肌电图（EMG）和神经传导速度（NCV）特征。其中20例患者的NCV明显减慢：正中神经感觉神经传导速度（Fing 1-W）X = 21.0米/秒，（Fing 3-W）X = 22.7米/秒，运动潜伏期（ML）X = 7.3毫秒；胫神经感觉神经传导速度（拇趾-踝关节）X = 22.2米/秒，ML = X = 8.1毫秒，这与1型PMA相符。12例患者的NCV正常或轻度减慢：正中神经感觉神经传导速度（Fing 1-W）X = 41.9米/秒，（Fing 3-W）X = 47.0米/秒，ML X = 3.2毫秒；胫神经感觉神经传导速度（拇趾-踝关节）X = 32.5米/秒，ML X = 4.8毫秒，这与2型PMA相符。这两组之间的差异非常显著（P小于0.01）。对6例患者进行了腓肠神经活检，结果显示5例与NCV分类相符。我们得出结论，仔细的NCV检查对于PMA的分类是必要的。
