Nerve conduction studies (NCSs) are essential for diagnosing various kinds of focal and diffuse neuropathies. Due to the paucity of local NCS data, electrodiagnostic laboratories in Punjab rely on values from Western and other Indian studies.
This study was conducted to provide normative data for median nerve conduction parameters (motor and sensory) in Punjabi populace.
A cross-sectional study was done on 290 participants (150 males and 140 females), aged 17-21 years, as per standardized protocol. The data were analyzed separately for both genders using SPSS version 20. It consisted of distal latencies and conduction velocities of motor and sensory divisions of median nerve. Student's unpaired -test was used for statistical analysis.
There was no effect of gender on any of the median nerve conduction parameters. Height and weight had nonsignificant negative and positive correlation, respectively ( > 0.05), with conduction velocity in both motor and sensory median nerves. For median motor nerve, the values of distal latency and conduction velocity in males were 2.9 ± 0.16 ms and 60.25 ± 2.99 m/s, respectively, whereas, in females, they were 2.6 ± 0.43 ms and 59.83 ± 2.82 m/s. Similarly, for median sensory nerve, the latency and velocity values in males were 2.8 ± 0.56 ms and 54.81 ± 3.70 m/s, whereas, in females, they were 2.4 ± 0.33 ms and 54.56 ± 3.65 m/s, respectively.
The data in this study compared favorably with already existing data. It would help the local electrodiagnostic laboratories in assessing the median nerve abnormalities with greater accuracy in this population subset.
神经传导研究（NCSs）对于诊断各种局灶性和弥漫性神经病变至关重要。由于当地NCS数据匮乏，旁遮普邦的电诊断实验室依赖西方和其他印度研究的数据。
本研究旨在提供旁遮普人群正中神经传导参数（运动和感觉）的标准数据。
按照标准化方案，对290名年龄在17 - 21岁的参与者（150名男性和140名女性）进行了横断面研究。使用SPSS 20版本对两性数据分别进行分析。研究内容包括正中神经运动和感觉分支的远端潜伏期和传导速度。采用学生非配对t检验进行统计分析。
性别对任何正中神经传导参数均无影响。身高和体重与正中神经运动和感觉分支的传导速度分别呈非显著的负相关和正相关（P>0.05）。对于正中运动神经，男性的远端潜伏期和传导速度值分别为2.9±0.16毫秒和60.25±2.99米/秒，而女性分别为2.6±0.43毫秒和59.83±2.82米/秒。同样，对于正中感觉神经，男性的潜伏期和速度值分别为2.8±0.56毫秒和54.81±3.70米/秒，而女性分别为2.4±0.33毫秒和54.56±3.65米/秒。
本研究的数据与现有数据相比具有优势。它将有助于当地电诊断实验室在该人群亚组中更准确地评估正中神经异常情况。
