Studying the human brain during interpersonal interaction allows us to answer many questions related to motor control and cognition. For instance, what happens in the brain when two people walking side by side begin to change their gait and match cadences? Adapted from the neuroimaging techniques used in single-brain measurements, hyperscanning (HS) is a technique used to measure brain activity from two or more individuals simultaneously. Thus far, HS has primarily focused on healthy participants during social interactions in order to characterize inter-brain dynamics. Here, we advocate for expanding the use of this electroencephalography hyperscanning (EEG-HS) technique to rehabilitation paradigms in individuals with neurological diagnoses, namely stroke, spinal cord injury (SCI), Parkinson’s disease (PD), and traumatic brain injury (TBI). We claim that EEG-HS in patient populations with impaired motor function is particularly relevant and could provide additional insight on neural dynamics, optimizing rehabilitation strategies for each individual patient. In addition, we discuss future technologies related to EEG-HS that could be developed for use in the clinic as well as technical limitations to be considered in these proposed settings.

运动康复中的脑电图超扫描：立场文件

在人际交往中研究人脑使我们能够回答许多与运动控制和认知相关的问题。例如，当两个并排行走的人开始改变他们的步态并匹配节奏时，大脑会发生什么？改编自单脑测量中使用的神经成像技术，超扫描 (HS) 是一种用于同时测量两个或多个个体的大脑活动的技术。到目前为止，HS 主要关注社交互动中的健康参与者，以表征大脑间动态。在这里，我们主张将这种脑电图超扫描 (EEG-HS) 技术的使用扩展到神经诊断患者的康复范例，即中风、脊髓损伤 (SCI)、帕金森病 (PD) 和创伤性脑损伤 (TBI) . 我们声称，运动功能受损的患者群体中的 EEG-HS 尤其相关，并且可以提供关于神经动力学的额外见解，优化每个患者的康复策略。此外，我们讨论了可以开发用于临床的与 EEG-HS 相关的未来技术，以及在这些建议设置中要考虑的技术限制。
