In order to determine the function of the autonomic nervous system in syringomyelia, the sympathetic skin response (SSR) was performed in 13 patients with syringomyelia and 20 healthy controls. SSR was recorded from both palms and soles. In patients with syringomyelia, we found absent responses, prolonged latencies and reduced amplitudes. SSRs could be recorded in 15 out of the examined 26 upper extremities. The latencies were prolonged in 12 of these cases. In the lower limbs, 11 SSRs could be obtained. In 4 of these cases the latencies were prolonged. The SSR latencies recorded from the palms and soles were both significantly prolonged (p < 0.05) and the amplitudes were reduced (p < 0.05) as compared to normal persons. Our data strongly suggest involvement of the autonomic nervous system in syringomyelia as assessed by the SSR response (in upper and lower extremities). In our patients, the extent of autonomic dysfunction was not related to the stage or the duration of disease.
为了确定自主神经系统在脊髓空洞症中的作用,对13例脊髓空洞症患者和20名健康对照者进行了交感神经皮肤反应(SSR)检测。SSR记录于手掌和足底。在脊髓空洞症患者中,我们发现反应缺失、潜伏期延长和波幅降低。在检查的26条上肢中,有15条可记录到SSR。其中12例潜伏期延长。在下肢,可获得11条SSR。其中4例潜伏期延长。与正常人相比,手掌和足底记录的SSR潜伏期均显著延长(p<0.05),波幅降低(p<0.05)。我们的数据强烈提示,通过SSR反应(在上肢和下肢)评估,自主神经系统参与了脊髓空洞症。在我们的患者中,自主神经功能障碍的程度与疾病分期或病程无关。
