In patients suffering from acute sciatica due to herniated disk Lasegue's manoeuvre inhibits the leg flexion nociceptive reflex (RIII reflex) in either the ipsilateral or the contralateral limb. This is thought to be due what is called "diffuse noxious inhibitor control" modulating the activity of a group of convergent spinal neurons. The purpose of this study was to determine whether surgical resection of the herniated disk in patients suffering from sciatica might relieve this so-called "counter-irritation". Among 10 patients whose sciatica resulted from herniated disk, the decrease in amplitude of the RIII response observed when Lasegue's manoeuvre is applied disappeared in 7 patients, 6 to 8 days after surgical resection of the herniated disk. These results suggest that this test might be a useful tool for postoperative prediction of radicular compression.
在因椎间盘突出症导致急性坐骨神经痛的患者中,拉塞格氏手法可抑制同侧或对侧肢体的腿部屈曲伤害性反射(RIII反射)。这被认为是由于所谓的“弥漫性伤害性抑制控制”调节了一组会聚性脊髓神经元的活动。本研究的目的是确定坐骨神经痛患者进行椎间盘突出手术切除是否可以缓解这种所谓的“对抗刺激”。在10例因椎间盘突出导致坐骨神经痛的患者中,7例患者在椎间盘突出手术切除后6至8天,应用拉塞格氏手法时观察到的RIII反应幅度下降消失。这些结果表明,该测试可能是术后预测神经根受压的有用工具。
