Effect of the different sensitizers of Straight leg Raise on conduction velocity characteristics of sciatic nerve in individuals with sciatica using NCV parameters

This dataset was derived from a cross-sectional study investigating the effect of different Straight Leg Raise (SLR) sensitizing maneuvers on motor nerve conduction velocity (MNCV) of the tibial and common peroneal nerves in individuals with sciatica. It was hypothesized that different sensitizers would produce variable effects on nerve conduction, with optimal mechanical loading enhancing neural transmission. Data were collected from 51 participants using nerve conduction studies under three SLR conditions: ankle-based sensitizer, hip adduction with internal rotation, and cervical flexion. The dataset includes MNCV values (Tibial_1, Tibial_2, Tibial_3, Peroneal_1, Peroneal_2, Peroneal_3), along with demographic variables and pain scores (VAS). The findings indicate that cervical flexion produced a significant increase in conduction velocity, whereas other sensitizers showed non-significant or variable responses, suggesting a dose-dependent relationship between mechanical neural loading and conduction characteristics. This dataset can be used to understand neurodynamic influences on nerve physiology and to support further research in electrophysiological assessment and rehabilitation of sciatica.

本数据集源自一项横断面研究（cross-sectional study），该研究探讨不同直腿抬高（Straight Leg Raise, SLR）致敏操作对坐骨神经痛患者胫神经与腓总神经运动神经传导速度（motor nerve conduction velocity, MNCV）的影响。研究假设不同致敏操作会对神经传导产生差异化影响，而适宜的机械负荷可增强神经传导功能。本研究共纳入51名受试者，在三种SLR操作条件下开展神经传导检测并收集数据，分别为踝部致敏操作、髋关节内收内旋操作以及颈椎屈曲操作。本数据集包含运动神经传导速度数值（Tibial_1、Tibial_2、Tibial_3、Peroneal_1、Peroneal_2、Peroneal_3），同时纳入人口学变量与疼痛评分（Visual Analogue Scale, VAS）。研究结果显示，颈椎屈曲操作可显著提升神经传导速度，而其余致敏操作未观察到显著影响或仅产生波动效应，这提示机械神经负荷与神经传导特性之间存在剂量依赖关系。本数据集可用于解析神经动力学对神经生理功能的影响，同时可为坐骨神经痛的电生理评估与康复相关后续研究提供支持。
