以任务为导向的重复运动可以改善神经系统或骨科疾病患者的运动能力。机器人和自动化技术的应用可以帮助、加强、评估和记录神经和骨科康复。本文讨论了“患者-合作”技术在机器人辅助步态康复中的应用。我们将患者合作定义为，在运动过程中，技术系统考虑患者的意图和自愿努力，而不是强加任何预先定义的运动或僵化的策略。与经典的康复策略相比，假设这种合作的机器人方法可以改善治疗结果。提出了新的合作策略来检测患者的自愿努力。首先，这使患者增加了一定程度的机器人依从性，行动自由。第二，机器人的行为适应了现有的自主运动能力。第三，机器人系统通过视觉生物反馈显示和改善患者的贡献。给出了初步的实验结果，以评估所提出的方法的基本原理和技术功能。还需要进一步改进技术设计和进行更多的临床试验，以证明这种合作策略是否可以改善治疗结果。
Task-oriented repetitive movements can improve motor performance in patients with neurological or orthopaedic lesions. The application of robotics and automation technology can serve to assist, enhance, evaluate, and document neurological and orthopedic rehabilitation. This paper deals with the application of "patient-cooperative" techniques to robot-aided gait rehabilitation of neurological disorders. We define patient-cooperative to mean that, during movement, the technical system takes into account the patient's intention and voluntary efforts rather than imposing any predefined movements or inflexible strategies. It is hypothesized that such cooperative robotic approaches can improve the therapeutic outcome compared to classical rehabilitation strategies. New cooperative strategies are presented that detect the patient's voluntary efforts. First, this enables the patient increased freedom of movement by a certain amount of robot compliance. Second, the robot behavior adapts to the existing voluntary motor abilities. And third, the robotic system displays and improves the patient contribution by visual biofeedback. Initial experimental results are presented to evaluate the basic principle and technical function of proposed approaches.. Further improvements of the technical design and additional clinical testing is required to prove whether the therapeutic outcome can be enhanced by such cooperative strategies.
