Abstract
We describe 2 instances where sciatic nerve block prevented pain in the sciatic nerve distribution caused by the nerve-root tension test in patients with radiculopathy. We hypothesize that antidromic activation of nociceptors from the injured root is a mechanism underlying sciatica.

我们描述了2例坐骨神经阻滞预防神经根病患者神经根张力试验引起的坐骨神经分布区疼痛的情况。我们推测，来自受损神经根的伤害感受器的逆向激活是坐骨神经痛的一种潜在机制。
