A novel cable-driven robotic gait training system has been tested to improve the locomotor function in individuals post stroke. Seven subjects with chronic stroke were recruited to participate in this 6 weeks robot-assisted treadmill training paradigm. A controlled assistance force was applied to the paretic leg at the ankle through a cable-driven robotic system. The force was applied from late stance to mid-swing during treadmill training. Body weight support was provided as necessary to prevent knee buckling or toe drag. Subjects were trained 3 times a week for 6 weeks. Overground gait speed, 6 minute walking distance, and balance were evaluated at pre, post 6 weeks robotic training, and at 8 weeks follow up. Significant improvements in gait speed and 6 minute walking distance were obtained following robotic treadmill training through a cable-driven robotic system. Results from this study indicate that it is feasible to improve the locomotor function in individuals post stroke through a flexible cable-driven robot.
一种新型的缆索驱动机器人步态训练系统已进行测试，以改善中风后个体的运动功能。招募了7名慢性中风患者参与这一为期6周的机器人辅助跑步机训练模式。通过缆索驱动机器人系统在脚踝处向患侧腿施加可控的辅助力。在跑步机训练期间，从站立后期到摆动中期施加该力。必要时提供体重支持以防止膝盖屈曲或足趾拖地。受试者每周训练3次，共6周。在机器人训练前、训练6周后以及随访8周时评估地面步行速度、6分钟步行距离和平衡能力。通过缆索驱动机器人系统进行机器人跑步机训练后，步态速度和6分钟步行距离有显著改善。这项研究结果表明，通过灵活的缆索驱动机器人改善中风后个体的运动功能是可行的。
