PI: Banerjee, Amarnath/Perez Gracia, Alba/Robson, NinaProposal Number: 1403502/1403688/1404011Title: Collaborative Research: ARWED - Augmented Perception for Upper-Limb RehabilitationBroader Significance & Importance Training and retraining the movement of individuals suffering loss of motor ability due to stroke is a challenging task. In many cases, only partial success is accomplished after long training sessions. Given the limitations of recovery for post-stroke patients, it is imperative that better tools and methods for retraining be developed. Even though several training hypotheses exist, such as need for an exact repetition of the training pattern, the solutions are still to be found. Overcoming some of these obstacles is the goal of this proposal. Recent studies show a direct link between human action perception and action execution. There is some evidence that the visual observation of human actions has an effect on the movement of the observer. This priming effect is reduced, or not present, when the motion is executed by a non-human device, such as a robot. This proposal aims to develop and test a novel wearable system for the training of the human arm. The system will allow the user to perceive the device as part of their upper limb (hence closing the perception/action loop). Training protocols based on observational learning findings will be implemented with the ARWED in order to develop it as rehabilitation training device for motor recovery in post-stroke patients.Technical description The intellectual merit centers on exploiting the link between action-observation and action execution in order to develop training protocols to facilitate rehabilitation following stroke. Currently, there are limited systems that utilize virtual reality in the relearning of biological movements. The proposed development of augmented wearable system (ARWED) requires solving several challenges in computer vision/modeling, and robot kinematic mapping. Testing the effectiveness of the device on priming the perception-action effect will require combined expertise from the areas of human kinematics, signal analysis, virtual reality, robotic fault recovery theory and rehabilitation. Therefore, the theoretical contributions emerging from this multidisciplinary collaborative research team will advance knowledge and understanding not only within the medical field, but also across the above-mentioned research areas. The broader impact is based on the characteristics of the device to be developed, with an expanded ability in the training and re-training of patients with motor disabilities. Efficient design and manipulation will make the proposed ARWED system a reliable solution, which will be broadly utilized by medical professionals working in rehabilitation, sports therapy and convalescence. The proposed research will provide effective tools for the training and physical rehabilitation of patients with limb limitations at any scale, ranging from individuals suffering partial loss of motor ability to those with severe limitations in mobility due to strokes, birth defects or accidents. Motor learning theory shows that reducing feedback during practice benefits long term retention of motor skill training. Observational learning may offer greater benefits regarding transfer to ADLs, in comparison to robotic-based stroke training. Thus, a success indicator for these patients would be the beneficial transfer of training from the un-affected to affected limb or vice-versa. The ARWED system is expected to advance significantly the fundamentals of engineering and scientific knowledge, by implementing the device in experimental and educational work on cognition, telemanipulation and virtual reality. The medical community would also benefit from the development of the ARWED by furthering the understanding of how training using technology may enhance the recovery of motor control in diverse populations while providing a novel intervention that may prove more effective than what is currently available. The collaborative nature of the research team will lead to the education of undergraduate and graduate students in the areas of Engineering and Kinesiology. In the long run, the outcomes of the proposal will facilitate the communication between students that want to enter Physical and Occupational Therapy professions and those that want to design and develop mechanical devices that can aid in human recovery following neurological injury.

Pi：Banerjee，Amarnath/Perez Gracia，Alba/Robson，Nina建议编号：1403502/1403688/1404011标题：合作研究：用于上肢康复的ARWED-增强感知广泛的重要性和重要性训练和再培训因中风而失去运动能力的个人的运动是一项具有挑战性的任务。在许多情况下，经过长时间的训练后，只取得了部分成功。鉴于中风后患者康复的局限性，迫切需要开发更好的工具和方法来进行再培训。尽管存在几个训练假设，如需要精确重复训练模式，但解决方案仍有待找到。克服这些障碍中的一些是这项提案的目标。最近的研究表明，人类的行动知觉和行动执行之间存在直接联系。有一些证据表明，对人类行为的视觉观察对观察者的运动有影响。当运动由诸如机器人之类的非人类设备执行时，该启动效果被降低或不存在。这项提议旨在开发和测试一种用于训练人类手臂的新型可穿戴系统。该系统将允许用户将设备感知为其上肢的一部分(从而关闭感知/动作环路)。ARWED将实施基于观察性学习结果的训练方案，以将其开发为中风后患者运动恢复的康复训练设备。技术描述智力优势集中在利用动作观察和动作执行之间的联系，以便开发训练方案，促进中风后的康复。目前，利用虚拟现实重新学习生物运动的系统有限。增强可穿戴系统(ARWED)的发展需要解决计算机视觉/建模和机器人运动学映射方面的几个挑战。测试该设备在启动感知-行动效果方面的有效性将需要来自人类运动学、信号分析、虚拟现实、机器人故障恢复理论和康复领域的综合专业知识。因此，这个多学科合作研究团队产生的理论贡献不仅将促进医学领域内的知识和理解，而且将跨越上述研究领域。更广泛的影响是基于将要开发的设备的特点，扩大对运动障碍患者的培训和再培训能力。高效的设计和操作将使拟议的ARWED系统成为一个可靠的解决方案，将被康复、运动治疗和康复工作的医疗专业人员广泛使用。拟议的研究将为任何规模的肢体受限患者提供有效的训练和身体康复工具，从部分运动能力丧失的人到因中风、出生缺陷或事故而行动能力严重受限的患者。运动学习理论表明，在练习中减少反馈有利于运动技能训练的长期保持。与基于机器人的中风训练相比，观察性学习可能会在转移到ADLS方面提供更大的好处。因此，对这些患者来说，一个成功的指标是将训练从未受影响的肢体转移到受影响的肢体，反之亦然。ARWED系统有望通过在认知、远程操纵和虚拟现实方面的实验和教育工作中实施该设备，显著提高工程和科学知识的基础。医学界也将从ARWED的开发中受益，通过进一步了解使用技术的培训如何在不同人群中增强运动控制的恢复，同时提供一种可能被证明比目前可用的更有效的新干预措施。研究团队的合作性质将导致工程和运动学领域的本科生和研究生的教育。从长远来看，该提案的结果将促进希望进入物理和职业治疗专业的学生与那些希望设计和开发能够帮助神经损伤后人类恢复的机械设备的学生之间的沟通。
