Abstract

Spinal cord injury (SCI) can disrupt the communication pathways between the brain and the rest of the body, restricting the ability to perform volitional movements. Neuroprostheses or robotic arms can enable individuals with SCI to move independently, improving their quality of life. The control of restorative or assistive devices is facilitated by brain-computer interfaces (BCIs), which convert brain activity into control commands. In this paper, we summarize the recent findings of our research towards the main aim to provide reliable and intuitive control. We propose a framework that encompasses the detection of goal-directed movement intention, movement classification and decoding, error-related potentials detection and delivery of kinesthetic feedback. Finally, we discuss future directions that could be promising to translate the proposed framework to individuals with SCI.

用于脊髓损伤患者手/臂控制的非侵入性脑机接口
脊髓损伤(SCI)可以破坏大脑和身体其他部分之间的沟通途径,限制进行意志运动的能力。神经假体或机械臂可以使脊髓损伤患者独立活动,提高他们的生活质量。脑机接口(bci)可以将大脑活动转化为控制命令,从而促进对恢复或辅助设备的控制。在本文中,我们总结了最近的研究成果,主要目的是提供可靠和直观的控制。我们提出了一个框架,包括目标导向的运动意图检测,运动分类和解码,错误相关的电位检测和传递动觉反馈。最后,我们讨论了未来的发展方向,有望将所提出的框架转化为SCI患者。
