Objective: We analysed the recovery function of somatosensory evoked potentials (SEPs) in juvenile myoclonic epilepsy (JME) patients. We hypothesized that there may be disinhibition in the recovery of SEPs at 20-100 ms intervals in JME patients. Methods: We recorded SEPs and SEP recovery in 19 consecutive patients with JME admitted for a routine follow-up examination, and in a control group composed of 13 healthy subjects who were similar to the patient group regarding age and sex. The recovery function of SEPs was examined using paired stimuli at 30, 40, 60, and 100 ms intervals. Results: The amplitudes of N20-P25 and P25-N33 components were higher in patients with JME. Ten patients had high-amplitude SEPs. By paired stimulation, there was inhibition of SEPs in both groups. The mean recovery percentages of N20-P25 and P25-N33 components at 30, 40, 60, and 100 ms were not different between healthy subjects and patients with JME. Conclusions: The recovery function of SEP is normal in JME even in the presence of high-amplitude SEPs.

体细胞感觉诱发电位在青少年肌阵挛性癫痫中的恢复功能。

目的：我们分析了青少年肌阵挛性癫痫（JME）患者的体感诱发电位（SEP）的恢复功能。我们假设JME患者以20-100 ms的间隔恢复SEP可能有抑制作用。方法：我们记录了连续接受常规随访检查的19例JME患者和13名健康受试者的对照组的SEP和SEP恢复情况，这些受试者在年龄和性别方面均与患者组相似。使用配对刺激以30、40、60和100 ms的间隔检查SEP的恢复功能。结果：JME患者的N20-P25和P25-N33成分的振幅更高。10例患者出现高振幅SEP。通过配对刺激，两组均抑制了SEP。N20-P25和P25-N33组分在30、40，健康受试者和JME患者之间60和100 ms并无差异。结论：即使存在高振幅SEP，JME中SEP的恢复功能也正常。
