一种新型的电缆驱动的机器人步态训练系统已被测试，以改善个人中风后的运动功能。招募了7名慢性卒中受试者参加为期6周的机器人辅助跑步机训练模式。通过电缆驱动的机器人系统，在踝关节处对麻痹腿施加受控的辅助力。在跑步机训练期间，从站立后期到摆动中期施加力。必要时提供体重支撑，以防止膝关节屈曲或脚趾拖曳。受试者每周训练3次，持续6周。在机器人训练前、训练后6周和随访8周时，对地上步态速度、6分钟步行距离和平衡进行评价。步态速度和6分钟步行距离的显着改善后，通过电缆驱动的机器人系统的机器人跑步机训练。本研究结果显示，利用柔索驱动机器人改善中风后病患之运动功能是可行的。
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.
