为了研究神经系统,特别是脊髓神经系统的功能状态和诊断某些脊髓疾病,脊电图(Spi-nal Electrograms,简称SEG)本是一个可取的临床电生理指标。但迄今为止,脊电图并没有如心电图、脑电图那样在临床上被广泛采用,这是因为以往所报告的记录脊电图的方法大都需要把记录电极直接放在脊髓表面,或借助于外科麻醉技术将电极插至硬脊膜下腔、硬脊膜外腔或蛛网膜下腔。这样的记录 In order to study the functional status of the nervous system, especially the spinal cord nervous system, and to diagnose some spinal diseases, Spi-nal Electrograms (SEG) are a promising clinical electrophysiological indicator. However, to date, there is not a wide range of clinical applications of electrograms like electrocardiogram and electrocardiogram, because most of the previously reported methods of recording electrograms need to place the recording electrodes directly on the surface of the spinal cord or by means of Surgical anesthesia inserts electrodes into the subdural, epidural or subarachnoid space.
