A functional electrical stimulation (FES) system was engineered to integrate information from a robotically controlled position during stepping in order to time stimulation to continuous gait information in a rodent model of spinal cord injury (SCI). In contrast to conventional FES systems which have a fixed timing pattern relative to gait cycle onset (i.e., toe off/heel off or paw contact/heel strike), this system allows adaptation of stimulation to a robotically controlled position. Rationale for the system design is presented along with bench-test results verifying the timing of the stimulation with respect to hindlimb position. This robotically timed FES system will enable studies investigating the capability of this FES therapy to encourage rehabilitation by way of spinal plasticity.
研制了一种功能性电刺激（FES）系统，以整合机器人控制的步行动作过程中的位置信息，以便为脊髓损伤（SCI）啮齿动物模型中的连续步态信息提供刺激。与传统的 FES 系统相比，该系统具有相对于步态周期开始的固定定时模式（即，脚趾离地/脚跟离地或爪子接触/脚跟撞击），该系统允许根据机器人控制的位置来调整刺激。本文介绍了系统设计的原理，并提供了验证刺激相对于后肢位置的定时的台架测试结果。这种机器人定时的 FES 系统将使研究能够通过脊髓可塑性来研究这种 FES 疗法促进康复的能力。
