| 摘 要： | 目的研究颈椎型脊髓病皮质体感诱发电位（ＳＥＰ）变化。方法对６５例颈椎型脊髓病患者和２６例正常人进行正中神经和胫后神经刺激的ＳＥＰ对照研究，并对１０例患者作治疗前后对照观察。结果本组异常率为４５％，主要表现为各波替伏期和波间期（Ｎ２０—Ｐ２５，Ｐ２５—Ｎ３５，Ｐ４０—Ｎ４５）延长，且下肢的延长更加明显，部分患者出现波形分化不良。经保守治疗后６例正常，２例好转，且ＳＥＰ的好转先于临床的改善。结论ＳＥＰ对评判颈椎型脊髓病的脊髓传导功能具有重要的意义，且有助于临床预后的评价。

| Abstract: | Objectives The function of spinal cord are evaluated with cortex somatosensory evoked potentials (SEP) in patients with cervical spondylotic myelopathy(CSM). Methods In sixty-five patients with CSM and 26 healty adults,SEP were performed by median and tibial nerve stimulation.The SEP were reperformed in ten of the patients after conservative treatment. Results Abnormality rate of SEP was 45%(29/65).The abnormal waves appeared as follow:latency delayed;inter-latency (N 20 -P 25 ,P 25 -N 35 ,P 40 -N 45 )delayed (tibial nerve more markedly);waveform being not clear in five patients.After conservative treatment,six patients of the ten patients were normal,and two patients had shorter latency(previouse to clinical symptom). Conclusions SEP can evaluate significantly conduction function of spinal cord of patients with CSM.SEP is helpful to evaluating prognosis of CSM. |
