DESCRIPTION (provided by applicant): The Virtual Occupational Therapy Assistant (VOTA) will enable stroke patients to practice activities of daily living (ADLs) as part of an in-patient, skilled nursing, outpatient, home health, and/or teletherapy rehabilitation program. The system leverages low-cost human motion tracking, advanced kinematic pose estimation algorithms, and state-of-the-art game engine technology to create a compelling world in which patients can perform realistic virtual ADLs that challenge both motor and cognitive function. The system's advanced human motion tracking capabilities enable automatic generation of performance metrics, supporting both user feedback and remote monitoring of user status by providers. VOTA also comprises an OT Dashboard that lets therapists track progress, plan activities, and interact with patients. Problem to be addressed: VOTA provides a tool for upper extremity (UE) rehabilitation, potentially benefiting approximately three quarters of a million individuals in the United States who are affected by stroke each year. VOTA addresses critical challenges of: (1) improving outcomes by enabling increased dosage and intensity in physical practice, and promoting cortical reorganization based on physical practice and mental imagery; (2) reducing costs by decreasing the time and expense associated with patient/therapist travel; and (3) providing services to remote and underserved areas. Long-Term Goal: Improve stroke rehabilitation outcomes through effective and efficient delivery of care. Phase I Results: Phase I produced a VOTA prototype application that includes a compelling virtual world, two virtual ADL activities, and automated generation of motor and cognitive metrics. A pilot study was conducted at the University of Virginia-HealthSouth Rehabilitation Hospital in Charlottesville, VA that involved 10 stroke patients. Analysis confirmed the primary Phase I hypothesis that VOTA-generated metrics correlate significantly with accepted measures of UE motor function. Subjective inquiry through patient interviews and questionnaires strongly supports acceptance of VOTA by stroke survivors for clinical or home health use. Phase II Summary: In the proposed Phase II SBIR effort, the team will develop a VOTA application suitable for use as a stroke intervention, demonstrate the efficacy of virtual ADL therapy for UE motor recovery, and establish the usability of the VOTA system by patients and providers. Development will include an expanded breadth and depth of virtual activities, provider tools for patient monitoring and planning, activity authoring tools, improved motion tracking, and teletherapy interfaces. The effort will culminate in randomized, controlled trials to investigate VOTA efficacy, as measured by improvement in standardized assessment scores. Commercial Opportunity: Barron Associates, Inc. is uniquely positioned to rapidly commercialize this technology. Participation by HealthSouth, the nation's largest provider of rehabilitative healthcare services, provides a springboard for the introduction of VOTA therapy in clinical, home health, and teletherapy settings.

描述（由申请人提供）：虚拟职业疗法助理（vota）将使中风患者能够练习日常生活活动（ADL），作为住院的一部分， 熟练的护理，门诊，家庭健康和/或远程疗法康复计划。该系统利用低成本的人类运动跟踪，高级运动姿势估计算法以及最先进的游戏引擎技术创造了一个引人注目的世界，在该世界中，患者可以执行逼真的虚拟ADL，从而挑战运动和认知功能。该系统的高级人体运动跟踪功能可以自动生成性能指标，从而支持用户反馈和提供者对用户状态的远程监视。 Vota还包括一个OT仪表板，可让治疗师跟踪进度，计划活动并与患者互动。待解决的问题：投票提供了上肢康复（UE）康复的工具，有可能受益于大约四分之三的一百万个人 每年受到中风影响的美国。 Vota解决了以下方面的关键挑战：（1）通过增加体力实践中的剂量和强度来改善结果，并根据身体实践和心理图像促进皮质重组； （2）通过减少与患者/治疗师旅行相关的时间和费用来降低成本； （3）为遥不可及的地区提供服务。长期目标：通过有效有效的护理提供改善中风康复结果。 第一阶段结果：第一阶段 制作了一个投票原型应用程序，其中包括引人入胜的虚拟世界，两个虚拟ADL活动以及自动产生的电动机和认知指标。在弗吉尼亚州夏洛茨维尔的弗吉尼亚 - 卫生康复医院进行了一项试点研究，该医院涉及10名中风患者。分析证实了I阶段的主要假设，即投票产生的指标与公认的UE运动功能量度显着相关。通过患者访谈和问卷进行的主观询问强烈支持中风幸存者接受临床或家庭健康使用的投票。第二阶段摘要：在拟议的II期SBIR工作中，该团队将开发适合用作中风干预的投票申请，证明虚拟ADL治疗对UE运动恢复的疗效，并确定患者和提供者对投票系统的可用性。开发将包括虚拟活动的广度和深度，用于患者监测和计划的提供商工具，活动创作工具，改进的运动跟踪以及远程疗法界面。这项工作将在随机，对照试验中达到高潮，以调查投票功效，这是通过改进标准化评估得分来衡量的。商业机会：Barron Associates，Inc。的独特位置可以快速商业化这项技术。美国最大的康复医疗保健服务提供商HealthSouth的参与为引入临床，家庭健康和远程疗法环境中的投票疗法提供了跳板。
