为了毫不费力地完成一个有意识的动作，大脑需要身体对动作进度的反馈。这种无意识的运动感觉帮助大脑学习运动命令和结果之间的关系，以纠正运动错误。用于恢复功能的假体系统主要集中在控制机动关节运动。然而，如果没有动觉，这些设备就不会变得直观可控。在这里，我们报告了一种方法，赋予人类截肢者与灵巧的机器人手的动觉感知。通过神经-机器接口振动用于假肢控制的肌肉，产生了复杂抓握动作的错觉。几分钟之内，三名截肢者整合了这种动觉反馈，改善了运动控制。将意图、动觉和视觉结合起来，让参与者对机器人的动作产生一种能动性。这种闭环控制的反馈方法为思想和机器的无缝集成开辟了一条道路。
To effortlessly complete an intentional movement, the brain needs feedback from the body regarding the movement’s progress. This largely non-conscious kinesthetic sense helps the brain to learn relationships between motor commands and outcomes to correct movement errors. Prosthetic systems for restoring function have predominantly focused on controlling motorized joint movement. Without the kinesthetic sense, however, these devices do not become intuitively controllable. Here we report a method for endowing human amputees with a kinesthetic perception of dexterous robotic hands. Vibrating the muscles used for prosthetic control via a neural-machine interface produced the illusory perception of complex grip movements. Within minutes, three amputees integrated this kinesthetic feedback and improved movement control. Combining intent, kinesthesia, and vision instilled participants with a sense of agency over the robotic movements. This feedback approach for closed-loop control opens a pathway to seamless integration of minds and machines.
