机器人技术和相关技术已经开始实现其改善康复治疗的承诺。然而，它们促进复苏的机制仍不清楚。最终，康复取决于生物学，但康复过程的细节在很大程度上仍然未知;更深入的了解对于加速机器人治疗的改进或提出新方法至关重要。幸运的是，机器人提供了一个很好的工具平台，可以从行为层面研究恢复。本文回顾了我们工作中出现的有关上肢行为恢复过程的一些初步见解。迄今为止的证据表明，治疗的形式可能比其强度更重要：肌肉强化与运动训练相比没有优势。被动的运动是不够的;需要积极的参与。基于运动协调措施的渐进式训练产生了显著改善的结果。总之，这些结果表明，运动协调，而不是肌肉激活可能是最合适的机器人治疗的重点。
Robotics and related technologies have begun to realize their promise to improve the delivery of rehabilitation therapy. However, the mechanism by which they enhance recovery remains unclear. Ultimately, recovery depends on biology, yet the details of the recovery process remain largely unknown; a deeper understanding is important to accelerate refinements of robotic therapy or suggest new approaches. Fortunately, robots provide an excellent instrument platform from which to study recovery at the behavioral level. This article reviews some initial insights about the process of upper-limb behavioral recovery that have emerged from our work. Evidence to date suggests that the form of therapy may be more important than its intensity: muscle strengthening offers no advantage over movement training. Passive movement is insufficient; active participation is required. Progressive training based on measures of movement coordination yields substantially improved outcomes. Together these results indicate that movement coordination rather than muscle activation may be the most appropriate focus for robotic therapy.
