摘要本文探讨电刺激器的控制，以恢复截瘫患者的站立功能。患者驱动的控制器是基于这样的知识，即使用支撑手柄站立，由神经上完整的自然运动控制系统引导，通过手臂起作用。患者驱动的控制器的一个类别是CHERMS（通过腿部肌肉刺激的手柄反应的控制）。第一个实验与患者驱动的控制器的报告。一名志愿者的CHARMS控制实验进行了描述。比例控制不允许受试者站起来，因为他使用的策略，但积分控制是成功的。有了它，他可以慢慢地站起来和坐下，完全由他自己引导，以及做其他动作。在不改变控制器模式的情况下，通过向前和向后倾斜，他可以“姿势转换”他的支撑肌肉。这些都是重要的成就，并证明了更大的研究病人驱动的控制器。讨论了该课题的控制策略。
Abstract This paper examines the control of electrical stimulators for restoring the standing function to paraplegics. Patient-driven controllers are based on the knowledge that standing, using support handles, is guided by the neurologically intact natural motor control system, acting through the arms. One category of patient-driven controller is CHRELMS (Control by Handle Reactions of Leg Muscle Stimulation). The first experiments with patient-driven controllers are reported. Experiments in the CHRELMS control of one volunteer are described. Proportional control did not allow the subject to stand up because of the strategy he used, but integral control was successful. With it, he could stand up and sit down slowly, entirely guided by himself, as well as making other manoeuvres. Without changing controller mode, and by leaning forwards and backwards, he could ‘posture switch’ his support muscles. These are significant achievements and justify a larger study of patient-driven controllers. The subject's control strategies are discussed.
