SmartAssist™: Adaptive robotic assistance to maximize patient engagement with the Barrett Upper-Extremity Robotic Trainer (Burt)

项目摘要 在中风康复中，患者参与治疗是改善功能结果的关键。机器人- 辅助康复可以根据患者的需要提供可重复的高强度治疗，而 也减轻了治疗师的负担。巴雷特上肢机器人训练器(BURT®)，FDA II级 由Barrett Technology开发和销售的医疗设备是一种机器人系统，可在 大型人类工作空间中的三维空间和引人入胜的患者界面，以加强治疗。 实现更个性化的治疗，最大限度地提高患者参与度，同时减轻负担 在治疗师方面，我们正在开发SmartAsset™，这是一种适用于BURT®的实时自适应机器人辅助模式， 鼓励患者尽可能使用自己的意志力动作。在以前的工作中，我们开发了 实时自适应BURT®系统的功能原型。在这个项目中，我们采取了以用户为中心的方法 继续开发，目标是(1)通过调整和新增功能来增强SmartAssistant™控制功能 用户要求的功能；(2)增加高级数据可视化功能，以确定困难领域； 以及(3)与Spaulding的研究人员合作进行初步临床研究，以评估疗效 康复医院。 这项工作的成果是具有SmartAssistant™的全功能自适应辅助BURT®系统，包括- 使用自适应辅助、直观的路径规范界面、数据可视化来支持多个Burt®游戏 帮助治疗师快速识别困难领域并调整他们的培训计划，并了解这些 功能可以改善患者的预后。我们还将完成一项随机对照试验，为我们提供 了解这些功能如何改善患者的预后。这将使我们为潜在的通信者做好准备- BURT®智能助理™系统的本地化，使高度个性化的培训在 美国在一个负担得起和用户友好的平台上。

Project Summary In stroke rehabilitation, patient engagement in therapy is critical for improving functional outcomes. Robot- assisted rehabilitation can provide repeatable, high-intensity therapy tailored to the needs of the patient, while also decreasing the load on the therapist. The Barrett Upper-Extremity Robotic Trainer (Burt®), an FDA Class-II medical device developed and sold by Barrett Technology, is a robotic system that provides active assistance in three dimensions in a large-human scale workspace and an engaging patient interface to enhance therapy. To enable more individualized treatment and maximize patient engagement while also reducing the burden on the therapist, we are developing SmartAssist™, a real-time adaptive robotic assistance mode for Burt® that encourages the patient to use their own volitional movement as much as possible. In previous work, we developed a functional prototype of the real-time adaptive Burt® system. In this project, we take a user-centered approach to continued development with goals of (1) enhancing the SmartAssist™ control functionality with tuning and new features as requested by users; (2) adding advanced data visualization features to identify areas of difficulty; and (3) conducting a preliminary clinical study to evaluate efficacy in partnership with researchers at Spaulding Rehabilitation Hospital. The deliverables of this work are a fully functional adaptive assistive Burt® system with SmartAssist™ includ- ing several Burt® games using adaptive assistance, an intuitive path specification interface, data visualization to help therapists quickly identify difficult areas and adapt their training plan, and an understanding of how these features can improve patient outcomes. We will also complete a randomised controlled trial, providing us with an understanding of how these features can improve patient outcomes. This will prepare us for potential commer- cialization of the Burt® SmartAssist™ system, making highly individualized training widely available across the U.S. on an affordable and user-friendly platform.
