我们测试了一种新的控制策略，用于中风后轻偏瘫患者使用的机器人康复设备。对称性阻力增加阻力时，肢体力量变得更加不对称，在双边行使。控制模式的基本原理是，它将指导患者增加瘫痪肢体的激活，同时教会他们准确测量相对于非瘫痪肢体的瘫痪肢体力产生。在为期一天的训练课程中，七名中风后受试者在机器人运动器械上以基于阻力的阻力模式进行下肢伸展。受试者在基于阻力的训练中将下肢对称性从28.6% ± 3.9%提高到36.2% ± 4.3%（ANOVA，P = 3D 0.03），但在恒定阻力后测试中没有保持改善的下肢对称性。在一天的训练期间显示出对称性的大幅改善的两名受试者进行了额外的训练天。这些结果表明，一些患者表现出长期持久的好处，以耐力为基础的阻力训练。
We tested a novel control strategy for robotic rehabilitation devices used by individuals with post-stroke hemiparesis. Symmetry-based resistance increases resistance when limb forces become more asymmetric during bilateral exercise. The underlying rationales for the control mode are that it will guide patients to increase paretic limb activation while teaching them to accurately gauge paretic limb force production relative to the non-paretic limb. During a one day training session, seven subjects post-stroke performed lower limb extensions in symmetry-based resistance mode on a robotic exercise machine. Subjects improved lower limb symmetry from 28.6% plusmn 3.9% to 36.2% plusmn 4.3% while under symmetry-based resistance training (ANOVA, P = 3D0.03), but did not maintain the improved lower limb symmetry during a constant resistance post-test. Two subjects that showed the large improvements in symmetry during the one day session performed additional days of training. Those results suggest that some patients demonstrate long lasting benefits with symmetry-based resistance training.
