摘要

这项工作提出了一个研究脑电图(EEG)信号时，突然出现的障碍，而受试者行走。主要目标是评估大脑活动如何因障碍物的存在而变化，以便将这些信息应用于可穿戴机器人的控制中，以执行下肢康复任务。对不同的反应进行了评估，结果表明，当障碍物出现时，EEG电位会发生变化，受试者会立即做出反应。电位与偶然性负性变异(CNV)的早期阶段具有相似的行为，反映了对预警信号的处理和对即将发生的事件的预期。

Changes in brain activity due to the sudden apparition of an obstacle during gait

This work presents a study of the electroencephalographic (EEG) signals when an obstacle suddenly appears while a subject walks. The main goal is to evaluate how the brain activity changes due to the presence of an obstacle in order to apply this information in the control of a wearable robot to perform lower limb rehabilitation tasks. Different responses were evaluated and the results reveal the existence of a change in the EEG potential when an obstacle appears and the subject reacts immediately to it. The potential has a similar behavior to the early stage of the contingent negativity variation (CNV) which reflects the processing of a warning signal and the anticipation to the upcoming event.
