Action observation (AO) is a promising strategy for promoting motor function in neural rehabilitation. Recently, brain–computer interface (BCI)-AO game rehabilitation, which combines AO therapy with BCI technology, has been introduced to improve the effectiveness of rehabilitation. This approach can improve motor learning by providing feedback, which can be interactive in an observation task, and the game contents of the BCI-AO game paradigm can affect rehabilitation. In this study, the effects of congruent rather than incongruent feedback in a BCI-AO game on mirror neurons were investigated. Specifically, the mu suppression with congruent and incongruent BCI-AO games was measured in 17 healthy adults. The mu suppression in the central motor cortex was significantly higher with the congruent BCI-AO game than with the incongruent one. In addition, the satisfaction evaluation results were excellent for the congruent case. These results support the fact that providing feedback congruent with the motion of an action video facilitates mirror neuron activity and can offer useful guidelines for the design of BCI-AO games for rehabilitation.

在脑机接口动作观察游戏中通过一致的角色运动对动作观察网络的优越促进

动作观察（AO）是促进神经康复运动功能的一种有前途的策略。最近，脑机接口（BCI）-AO游戏康复，将AO疗法与BCI技术相结合，被引入以提高康复效果。这种方法可以通过提供反馈来改善运动学习，在观察任务中可以交互，并且 BCI-AO 游戏范式的游戏内容可以影响康复。在这项研究中，研究了 BCI-AO 游戏中一致而非不一致反馈对镜像神经元的影响。具体而言，在 17 名健康成人中测量了一致和不一致 BCI-AO 游戏的 mu 抑制。一致 BCI-AO 游戏的中央运动皮层的 mu 抑制显着高于不一致的游戏。此外，一致情况下的满意度评价结果非常好。这些结果支持这样一个事实，即提供与动作视频运动一致的反馈有助于镜像神经元活动，并且可以为 BCI-AO 康复游戏的设计提供有用的指导。
