对２９例脊髓纵裂患者（手术组２０例，非手术组９例）行胫后神经皮层体感诱发电位（ＰＴＮＣＳＥＰ）测量研究，２０例正常儿童为对照组，结果显示：患病组ＰＴＮＣＳＥＰ明显异常，两下肢间的ＰＴＮＣＳＥＰ有显著性差异（Ｐ＜０．０５）；手术组患者手术后ＰＴＮＣＳＥＰ明显改善（Ｐ＜０．０５），非手术组患者随访发现ＰＴ－ＮＣＳＥＰ无改善（Ｐ＞０．０５）。结果表明：ＰＴＮＣＳＥＰ是一敏感、客观、可靠的诊断工具，可用来判断脊髓纵裂神经损害的程度及机理，评价手术效果，指导手术治疗
Twenty-nine patients with spinal cord rupture (20 cases in operation group and 9 cases in non-operation group) were measured by PTNCSEP. Twenty normal children were used as control group. The results showed that PTNCSEP was significantly abnormal (P <0.05). The PTNCSEP in the operation group was significantly improved (P <0.05). The non-operation group showed no improvement in the PT-NCSEP (P> 0.05). 05). The results show that PTNCSEP is a sensitive, objective and reliable diagnostic tool that can be used to determine the extent and mechanism of longitudinal nerve damage in the spinal cord, to evaluate the surgical results and to guide the surgical treatment
