颈椎病患者短潜时体感诱发电位的初步研究

Primary Study of Short Latency Somatosensory EvokedPotentials in Patients with Cervical Spondylopathy

为探讨短潜时体感诱发电位对颈椎病诊断的意义 ,检测了 15例颈椎病患者的短潜时体感诱发电位(SSEP) ,并与对照组比较。结果表明 :颈椎病患者SSEP的N2 0、P2 5波潜伏期及N13～N2 0峰间潜伏期 (即中枢神经传导时间 ,CCT)和N13～P2 5峰间潜伏期均比对照组明显延长 ,其SSEP异常率为 73.3%。提示短潜时体感诱发电位检查能客观评价颈椎病患者的神经功能 ,有助于评价疗效和判断预后。

To explore the significance for examinations of short latency somatosensory evoked potentials (SSEP) in the patients with cervical spondylopathy. The SSEP were examined in 15 cases of cervical spondylopathy, and were compared with normal control group. Results showed the peak latencies of N20 and P25, interpeak latencies of N13～N20 and N13～P25 of SSEP in cervical spondylopathy were significantly prolonged. The abnormal rate of SSEP in the patients with cervical spondylopathy was 73.3 %. SSEP test is a sensitive, objective and simple electrophysiological method for detecting nerve dysfunction in cervical spondylopathy and helpful to locational diagnosis and estimate prognosis.
