目的：探讨躯体形式疼痛障碍（SPD）听觉认知性事件相关电位P30的特点。方法：应用日本MEB-9200肌电图/诱发电位仪进行P30检测，对40例持续性躯体形式疼痛障碍患者（研究组）与40例健康成年人（对照组）P30的潜伏期、波幅、靶刺激反应时以及反应准确率进行比较。结果：与对照组相比，研究组Cz-A+导联P30(P3a、P3b)潜伏期延迟（P＜0.01），P30（P3b、N2-P3b）波幅降低（P＜0.05），靶刺激反应时（ms）延迟与反应准确率均降低（P＜0.01），差异均具有统计学意义（P＜0.05）。结论：躯体形式疼痛障碍患者存在认知功能损害，且P30变化诸特点值得进一步随访。

Objective:To study characteristic of event-related potentials P300 in patients with somatoform pain disorder(SPD).Methods:With Japanese MEB-9200 Electromyography / Evoked potentiometer, P300 test was carried out in 40 patients with somatoform pain disorder(research group)and 40 healthy adult controls(control group), and then latency, amplitude, response times to target stimuli and response accuracy rates of the two groups, P300 were compared and analyzed.Results:Compared with the control group, Cz- A+ lead P300(P3a,P3b)latencies were delayed(P<0.01) in research group, P300(P3b,N2-P3b)amplitudes were lower in research group (P<0.05), response times to target stimuli and response accuracy rates were lower in research group (P<0.01),al these differences were statisticaly significant (P<0.05).Conclusion:Somatoform pain disorder have cognitive impairments,and the characteristic of P300 of PSPD deserve further folowing up.
