The study investigated stimulus evaluation time, event preparation, and motor action planning of patients with mild spastic cerebral palsy and a peer control group in the age range of 9 to 18 years. To this end, participants were carrying out a stimulus recognition task. Findings indicated an overall slowness and inaccurate reaction time performance of the patient group. An event-related potential analysis revealed that the stimulus evaluation processing, indexed by the parietal P300, was intact in the group of patients. Also event preparation and action planning, indexed by respectively the frontal late contingent negative variation and the frontal P2, were intact in the group of patients. It was concluded that patients' motor slowness reflected poor motor execution processes.
该研究调查了年龄在9至18岁之间的轻度痉挛性脑瘫患者及同龄对照组的刺激评估时间、事件准备和运动动作规划。为此，参与者进行了一项刺激识别任务。研究结果表明，患者组总体反应缓慢且反应时间表现不准确。一项事件相关电位分析显示，以顶叶P300为指标的刺激评估过程在患者组中是完整的。同样，分别以前额叶晚期继时性负变化和额叶P2为指标的事件准备和动作规划在患者组中也是完整的。研究得出结论，患者的运动迟缓反映了运动执行过程不佳。
