DESCRIPTION (provided by applicant): The Virtual Occupational Therapy Assistant (VOTA) leverages advances in human motion tracking, multi-user virtual environments, and Voice over Internet Protocol (VoIP) technology to provide cost effective clinical rehabilitation and teletherapy options for the approximately three quarters of a million individuals in the United States affected by stroke each year. The system, consisting of web browser-based software and a desktop USB computer peripheral, will enable patients to practice activities of daily living (ADLs) as part of an in-patient, skilled nursing, outpatient, or home health treatment program. At the core of the proposed application is a high-fidelity computer-generated environment in which a patient's real-world upper extremity (UE) pose is mirrored by their virtual character. In both therapist-supervised and independent practice, a desktop motion tracking system will permit realistic interactions in scenarios spanning personal hygiene, dressing, eating, meal preparation, shopping, laundry, cleaning, telephone use, medication management, fire safety, and dangerous situation awareness. In home health usage, the system will permit the therapist to work with a remotely located patient, promoting continuity of care and saving travel-associated time and cost. Problem to be addressed: By enabling at-home practice of virtual ADLs and remote interaction between therapist and patient, VOTA addresses critical challenges of (1) reducing cost through elimination of the time and expense associated with patient/therapist travel; (2) increasing access to remote and underserved areas; (3) enhancing cortical reorganization through physical practice and mental imagery. Long-Term Goal: Improve stroke rehabilitation outcomes through effective and efficient delivery of care. Phase I Summary: Barron Associates, in partnership with the University of Virginia (UVA) School of Medicine, UVA-HealthSouth Rehabilitation Hospital, and Designing Digitally, Inc., will develop and test a prototype desktop UE motion tracking USB computer peripheral and web-based virtual worlds application software based on ecologically valid environments and activities on an "OT Island." Design efforts will focus on system usability and the experience of providers and patients. In the latter half of the effort, UVA-HealthSouth therapists will conduct a pilot study to assess the correlation of VOTA-derived performance scores to clinically accepted measures of ADL functionality as well as system usability/likelihood of use by patients. These efforts will providea solid basis of knowledge for subsequent Phase II design of the VOTA commercial product and human participant trials of the effectiveness of VOTA therapy in both clinical and home health settings. Commercial Opportunity: Participation by HealthSouth, the nation's largest provider of rehabilitative healthcare services, provides a springboard for the introduction of subscription-based access to web-based VOTA software and sale of the desktop UE motion tracking computer peripheral. PUBLIC HEALTH RELEVANCE: The Virtual Occupational Therapy Assistant (VOTA) is a virtual reality-based telerehabilitation system enabling functional practice of activities of daily living through a conventional web browser and a desktop motion tracking USB computer peripheral. Proposed development addresses important public health concerns by (1) enabling remote interaction between patient and therapist during online functional training; (2) reducing cost through elimination of the time and expense associated with patient/therapist travel; (3) increasing access to remote and underserved areas; (4) enhancing cortical reorganization through physical practice and mental imagery; and (5) providing reliable tracking mechanisms for patient activity and functional status.

描述（由申请人提供）：虚拟职业治疗助理（投票）利用人类运动跟踪，多用户虚拟环境和通过Internet协议（VOIP）技术的进步来为每年受ptroke受影响的大约四分之三的人提供成本效益的临床康复和远程治疗方案。该系统由基于Web浏览器的软件和桌面USB计算机外围设备组成，将使患者能够作为住院医师，熟练的护理，门诊或家庭健康治疗计划的一部分练习日常生活（ADL）。拟议应用程序的核心是一个高保真的计算机生成的环境，其中患者的现实世界上肢（UE）姿势以其虚拟特征镜像。在治疗师的监督和独立实践中，桌面运动跟踪系统将允许在涵盖个人卫生，敷料，饮食，饮食，购物，购物，洗衣，清洁，电话使用，药物管理，消防安全和危险情况意识的情况下进行现实的互动。在家庭健康使用中，该系统将允许治疗师与远程患者一起工作，从而促进护理的连续性并节省与旅行相关的时间和成本。待解决的问题：通过实现虚拟ADL的实践和治疗师与患者之间的远程相互作用，Vota解决了（1）通过消除与患者/治疗师旅行相关的时间和费用来降低成本的关键挑战； （2）增加对遥远和服务不足的地区的访问； （3）通过身体实践和心理图像增强皮质重组。长期目标：通过有效有效的护理提供改善中风康复结果。第一阶段摘要：Barron Associates与弗吉尼亚大学（UVA）医学院，UVA-Healthsouth康复医院以及Digititally Inc.设计，将开发和测试基于生态有效环境的原型台式UE运动跟踪USB计算机外围和基于Web的Virtual Worlds Application，基于生态有效的环境和基于生态上有效的环境和活动，这些软件基于生态上有效的环境和活动。设计工作将集中于系统可用性以及提供者和患者的经验。在努力的后半部分，UVA-Healthsouth治疗师将进行一项试点研究，以评估投票衍生的绩效评分与临床接受的ADL功能措施以及患者使用的系统可用性/可能性的相关性。这些努力将提供知识的扎实基础，以进行投票商业产品和人类参与者试验的II阶段设计，以了解投票疗法在临床和家庭健康环境中的有效性。商业机会：美国最大的康复医疗保健服务提供商HealthSouth参与，为引入基于订阅的基于Web的Vota软件的访问和销售台式UE运动跟踪计算机外围提供了跳板。 公共卫生相关性：虚拟职业疗法助理（投票）是一个基于虚拟现实的远程访问系统，实现了日常活动的功能实践 通过传统的网络浏览器和台式运动跟踪USB计算机外围设备。拟议的开发通过（1）在在线功能培训期间实现患者与治疗师之间的远程互动来解决重要的公共卫生问题； （2）通过消除与患者/治疗师旅行相关的时间和费用来降低成本； （3）增加对遥远和服务不足的地区的访问； （4）通过体育练习和心理图像增强皮质重组； （5）为患者活动和功能状态提供可靠的跟踪机制。
