这个单一的情况下，多对照研究说明了ERPs的临床使用的语言和认知评估的个人谁是无法提供口头或运动反应，由于他们的多重障碍的一部分。采用事件相关电位（ERP）范式，对1例17岁脑瘫患者和3名年龄匹配的正常对照进行了单字接受性词汇测试。皮博迪图片词汇测试修订版（PPVT-R）适用于计算机演示，有三个难度级别（学龄前，儿童，成人）。个别图片先后提出，并正确（一致）或不正确（不一致）命名命名。ERP组件的一致性和不一致的图片词对。正如所预测的那样，N400 ERP组件有一个较高的峰值不一致的图片-单词对在学前和儿童水平。在成人水平上，CP患者和三个对照组中的两个的ERP模式被逆转（一致条件下的较高峰值），并且第三个对照组的ERP模式大幅衰减。这些ERP结果表明，图片-词对的范围内获得的接受性词汇被确定为正确或不正确的，但图片-词对以上的个人的水平不能区分清楚。研究结果表明，这种模式的临床应用，以评估接受性词汇在运动和沟通障碍的患者。
This single-case, multiple-control study illustrates the clinical use of ERPs as part of the linguistic and cognitive assessment of individuals who are unable to provide verbal or motor responses due to their multiple handicaps. The single-word receptive vocabulary of a 17-year-old patient with Cerebral Palsy (CP) and three age-matched controls was measured using an event-related potential (ERP) paradigm. The Peabody Picture Vocabulary Test-Revised (PPVT-R) was adapted for computer presentation, with three levels of difficulty (Preschool, Child, Adult). Individual pictures were presented successively, and correctly (congruent) or incorrectly (incongruent) named auditorially. ERP components were derived for both the congruent and incongruent picture-word pairs. As predicted, the N400 ERP component had a higher peak for the incongruent picture-word pairs at the Preschool and Child levels. At the Adult level, the ERP pattern was reversed (higher peak in congruent condition) for the CP patient and for two of the three controls and, it was substantially attenuated for the third control. These ERP findings indicated that picture-word pairs within the range of acquired receptive vocabulary were identified as correct or incorrect, but picture-word pairs above an individual's level could not be differentiated as clearly. The findings demonstrate the clinical application of this paradigm to assessing receptive vocabulary in motor- and communication-impaired patients.
