特发性震颤是最常见的病理性震颤，被认为起源于中枢神经系统。它可能导致功能障碍，因为震颤阻碍运动。我们已经开发了一种软外装服来辅助特发性震颤患者，该软外装服为人体提供舒适、不显眼和柔软的界面，并评估了它是否可以限制关节运动和抑制震颤。我们开发了一种基于三点固定的原型电缆驱动的机器护甲，仅在必要时限制关节运动。使用功能性电刺激在健康受试者中模拟震颤。实验结果表明，在约束模式下获得的震颤强度约为62%，在无约束模式下获得的。这些结果表明，电缆驱动的软机器护甲有效地抑制了模拟原发性震颤患者的关节运动。我们还证明了机器护甲可以在约束和非约束模式之间切换。
Essential tremor, the most common pathological tremor, is assumed to originate in the central nervous system. It can result in functional disability because the tremors obstruct movement. We have developed a soft exosuit to assist essential tremor patients that provides a comfortable, unobtrusive and soft interface to the human body, and evaluated whether it can constrain joint movement and suppress tremors. We developed a prototype cable-driven exosuit based on three-point fixation that restricts joint motion only when necessary. Tremors were simulated in healthy test subjects using functional electrical stimulation. The experimental results show that the tremor intensity obtained with the exosuit in constrained mode was approximately 62% of that obtained in unconstrained mode. These results show that the cable-driven soft exosuit effectively suppressed joint motion in patients with simulated essential tremor. We also demonstrated that the exosuit could switch between constrained and unconstrained modes.
