The inhibitory effects of acute pain produced by the Lasègue's manoeuvre on the lower limb nociceptive flexion reflexes induced by electrical sural nerve stimulation were explored in patients complaining of sciatica as a result of an identified unilateral disc protrusion. Lassègue's manoeuvre on the affected side produced a typical radicular pain and resulted in a powerful depression of nociceptive reflexes elicited either in the normal or in the affected lower limb. Simultaneously, patients reported relief of the electrically-induced pain. In contrast, painless Lasègue's manoeuvre on the normal side had no effect on these parameters.
对于因明确的单侧椎间盘突出而患有坐骨神经痛的患者,研究了直腿抬高试验产生的急性疼痛对电刺激腓肠神经诱发的下肢伤害性屈曲反射的抑制作用。患侧的直腿抬高试验产生典型的神经根性疼痛,并导致正常或患侧下肢诱发的伤害性反射显著抑制。同时,患者报告电诱发疼痛减轻。相比之下,正常侧无痛的直腿抬高试验对这些参数没有影响。
