【摘要 】目的对脊髓损伤后的肢体幻像现象进行临床分析,并对其发生机理进行探讨。方法通过对28例脊髓损伤患者6～36个月的随访，对脊髓损伤后肢体幻像的类型、性质、出现和消失时间、伤后意识障碍的有无与肢体幻像的关系等进行了分析研究。结果根据患者对麻痹肢体感觉的不同，肢体幻像可分为位置幻像和截肢幻觉两种类型。大部分肢体幻像发生于损伤初期，多在伤后半年内消失。肢体幻像的发生与伤后意识障碍之间没有明显的相关性。结论脊髓损伤后肢体幻像现象的发生可能是由于末梢神经向中枢神经传导中断而引发的异常神经活动所致。肢体幻像是一种可以随着视觉信息的不断输入而得到修正，可以自行消失的现象。

【Abstract 】Objective To investigate thephantom limb phenomena following spinal cord injury and its pathological mechanism.MethodsTwenty-eight patients with complete spinal cord injury were inter-viewed in an averageperiod of 20 months(range:6 to 36 months).The types and duration of phantom limb,and thecorrelation between phantom limb and temporary unconsciousness following the injury werestudied.Results The phantom limbs were classified into phantom position and amputationillusion based on patient’s imagination.In most of the cases,phantom limb occurred earlyafter the spinal cord injury and disappeared within half a year.There was no correlationbetween phantom limb and temporary unconsciousness following the injury.Conclusion Thephantom limb phenomena may attribute to abnormal nerve activities resulted from theinterruption of afferent impulse from the periphery to central nerve system.Phantom limbis a re-versible phenomenon with continued input of visual information,and is a selflimited condition.
