我们描述了一位14岁女孩的自发性复杂区域疼痛综合征，首先发生在左臂，两年后出现在右脚。体格检查显示触觉和热敏异常。刺激右脚后的激光诱发电位(LEP)在急性期消失，5个月后逐渐恢复，与临床变化相关。据我们所知，复杂区域疼痛综合征中LEPS的系统分析尚未发表。我们认为，观察到的电生理改变可能是由于注意系统的暂时性功能障碍造成的，这被认为对LEPS顶点复合体有很大贡献。需要进一步的研究来检验这一假设。
We describe a case of spontaneous complex regional pain syndrome developing first in the left arm and 2 years later in the right foot of a 14-year-old girl. Physical examination showed abnormalities in tactile and thermal sensitivity. Laser-evoked potentials (LEPs) after stimulation of the affected right foot were absent in the acute phase and then progressively recovered over a period of 5 months, in correlation with clinical changes. To our knowledge, no systematic analysis of LEPs in complex regional pain syndrome has been published. We suggest that the observed electrophysiologic alterations could result from a temporary dysfunction of attentional systems, which are assumed to contribute greatly to the LEPs vertex complex. Further studies are needed to test this hypothesis.
