Reappearance of sympathetic skin response (SSR) below lesion is reported in a patient with a complete thoracic-9 spinal cord injury 6 months following injury. SSR was elicited by electrical stimulation of supraorbital nerve (SON) and pudendal nerve (PN). SON stimulation induced SSRs only in the hand. SSRs were initially absent below the level of SCI but reappeared only with PN stimulation. This case suggests that 6 months following a complete lesion, the isolated spinal cord can generate a SSR. Possible underlying mechanisms and implications for autonomic plasticity below spinal lesion are discussed in view of the literature.
报道了 1 例完全性胸 9 脊髓损伤患者,在损伤后 6 个月时,损伤以下部位出现交感皮肤反应(SSR)。SSR 通过眶上神经(SON)和阴部神经(PN)电刺激诱发。SON 刺激仅在手区诱发出 SSR。SSR 在 SCI 以下水平最初缺失,但仅在 PN 刺激时再次出现。该病例提示,在完全损伤后 6 个月,孤立的脊髓可以产生 SSR。鉴于文献,讨论了脊髓损伤以下自主神经可塑性的潜在机制和意义。
