摘要
由一位新闻记者兼机器人与机器学习的工作人员新闻编辑每日新闻-机器人的新研究是一份报告的主旨。根据NewsRx Journ Alists在奥地利维也纳的新闻报道，研究表明：“假肢控制的感觉反馈通常是基于特定类型的感觉刺激中编码的感觉信息，使用者解释这些信息来调节假肢的控制。然而，在生理条件下，从周围神经接收到的传入反馈不仅是有意识的处理，而且还调节脊神经反射环路，这些环路有助于驱动肌肉的神经信息。新闻记者从维也纳医科大学的研究中获得了一句话：“脊柱通路与感觉-运动整合有关，”本文提出了一种改善假肢控制中感觉-运动整合的方法，该方法通过肌肉活动的闭环肌腱振动来调节脊髓回路的兴奋性，并对健康受试者和截肢者在不同运动任务下的肌肉信号进行了测量。在与肌肉相连的肌腱上施加V形振动，调节运动神经元的兴奋性，从而使假肢的控制信号是主动控制和肌腱振动引起的附加脊髓反射输入的组合，结果表明，闭环肌腱振动能够调节对肌肉的神经驱动，当使用闭环肌腱振动时，通过肌肉激活，部分参与者可以在界面上获得相似或更好的控制性能。刺激甚至可以改善截肢者的假肢抓握。
Abstract
By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News – New research on Robotics is the subjec t of a report. According to news reporting from Vienna, Austria, by NewsRx journ alists, research stated, “Sensory feedback for prosthesis control is typically b ased on encoding sensory information in specific types of sensory stimuli that t he users interpret to adjust the control of the prosthesis. However, in physiolo gical conditions, the afferent feedback received from peripheral nerves is not o nly processed consciously but also modulates spinal reflex loops that contribute to the neural information driving muscles.” The news correspondents obtained a quote from the research from the Medical Univ ersity of Vienna, “Spinal pathways are relevant for sensory-motor integration, b ut they are commonly not leveraged for prosthesis control. We propose an approac h to improve sensory-motor integration for prosthesis control based on modulatin g the excitability of spinal circuits through the vibration of tendons in a clos ed loop with muscle activity. We measured muscle signals in healthy participants and amputees during different motor tasks, and we closed the loop by applying v ibration on tendons connected to the muscles, which modulated the excitability o f motor neurons. The control signals to the prosthesis were thus the combination of voluntary control and additional spinal reflex inputs induced by tendon vibr ation. Results showed that closed-loop tendon vibration was able to modulate the neural drive to the muscles. When closed-loop tendon vibration was used, partic ipants could achieve similar or better control performance in interfaces using m uscle activation than without stimulation. Stimulation could even improve prosth etic grasping in amputees.”
