To generate a large normative database for the peroneal study to the tibialis anterior and to analyze differences between the peroneal latency to the extensor digitorum brevis and the tibial latency to the abductor hallucis.
A total of 244 asymptomatic subjects without risk factors for neuropathy were tested for latency, amplitude, area, duration, and nerve conduction velocity to the tibialis anterior. For the peroneal/tibial analysis, 221 subjects were included. Temperature control was used, and demographic characteristics were recorded.
Latency to the tibialis anterior increased and nerve conduction velocity decreased with increasing height. Amplitudes, area, and nerve conduction velocity were lower in older persons. The upper limits of normal (97th percentile) were 4.9 msec (latency) and 15.0 msec (duration). The lower limits of normal (3rd percentile) were 1.7 mV (amplitude), 6.8 microV/sec (area), and 43 m/sec (nerve conduction velocity). The upper limits of normal side-to-side difference was 1.2 msec (latency), 6.3 msec (duration), 50% (amplitude), 47% (area), and 20% (nerve conduction velocity). The upper limits of normal drop from below- to above-fibular-head stimulation was 36% (amplitude) and 43% (area). For the peroneal/tibial comparison, the upper limits of normal latency increase of peroneal over tibial was 1.8 msec and tibial over peroneal was 1.5 msec.
A large normative database was collected. Upper and lower limits of normal were calculated, and side-to-side differences were analyzed. For the peroneal/tibial comparison, an upper limits of normal difference was described.
为腓骨至胫骨前肌研究建立一个大型的正常数据库，并分析腓骨至趾短伸肌潜伏期与胫神经至拇短展肌潜伏期之间的差异。
对244名无神经病变危险因素的无症状受试者进行了至胫骨前肌的潜伏期、波幅、面积、时限及神经传导速度测试。在腓骨/胫神经分析中，纳入了221名受试者。采用了温度控制，并记录了人口统计学特征。
至胫骨前肌的潜伏期随身高增加而延长，神经传导速度随身高增加而减慢。老年人的波幅、面积和神经传导速度较低。正常上限（第97百分位数）分别为4.9毫秒（潜伏期）和15.0毫秒（时限）。正常下限（第3百分位数）分别为1.7毫伏（波幅）、6.8微伏/秒（面积）和43米/秒（神经传导速度）。正常左右差值上限分别为1.2毫秒（潜伏期）、6.3毫秒（时限）、50%（波幅）、47%（面积）和20%（神经传导速度）。腓骨小头下方至上方刺激时波幅正常下降上限为36%，面积为43%。在腓骨/胫神经比较中，腓骨潜伏期较胫神经潜伏期正常增加上限为1.8毫秒，胫神经较腓骨潜伏期正常增加上限为1.5毫秒。
收集了一个大型的正常数据库。计算了正常上限和下限，并分析了左右差值。在腓骨/胫神经比较中，描述了正常差值上限。
