The change of P300 wave amplitude and latency were corresponding to the pain degree in different stage.
P 300波幅和潜伏期的变化与不同时期疼痛程度相对应。
Endogenous components of ERP: The P300 potential (P3 wave) of abnormal degree among every group was different.
①事件相关电 位的内 源成分：P300电 位（即P3波）在各组间异常程度不同。
Results Compared with controls, the observation group manifested shorter latency and higher amplitude on Target P3 wave of P300 after treatment(P<0.01 or 0.05).
结果综合康复训练后，实验组P300靶刺激P3潜伏期缩短和波幅升高（P<0.01）；
