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）：虚拟职业治疗助理（VOTA）将使中风患者能够作为住院患者的一部分进行日常生活活动（ADL）， 专业护理、门诊、家庭健康和/或远程治疗康复计划。该系统利用低成本的人体运动跟踪、先进的运动姿态估计算法和最先进的游戏引擎技术，创造了一个令人信服的世界，患者可以在其中执行挑战运动和认知功能的逼真虚拟ADL。该系统先进的人体运动跟踪功能可以自动生成性能指标，支持用户反馈和提供商对用户状态的远程监控。VOTA还包括一个OT仪表板，让治疗师跟踪进展，计划活动，并与患者互动。需要解决的问题：VOTA为上肢（UE）康复提供了一种工具，可能使美国约75万人受益。 美国每年有多少人受到中风的影响。VOTA解决了以下关键挑战：（1）通过增加身体练习的剂量和强度来改善结果，并促进基于身体练习和心理意象的皮质重组;（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）为偏远和服务不足的地区提供服务。长期目标：通过有效和高效的护理服务改善卒中康复结果。 I期结果：I期 制作了一个VOTA原型应用程序，其中包括一个引人注目的虚拟世界，两个虚拟ADL活动，以及自动生成的运动和认知指标。在弗吉尼亚州夏洛茨维尔的弗吉尼亚大学健康南方康复医院进行了一项试点研究，涉及10名中风患者。分析证实了第一阶段的主要假设，VOTA生成的指标与UE运动功能的公认测量值显著相关。通过患者访谈和问卷调查进行的主观调查强烈支持卒中幸存者接受VOTA用于临床或家庭健康用途。II期总结：在拟议的第二阶段SBIR工作中，该团队将开发适合用作中风干预的VOTA应用程序，证明虚拟ADL治疗对UE运动恢复的有效性，并确定患者和提供者对VOTA系统的可用性。开发将包括扩展虚拟活动的广度和深度，用于患者监测和规划的提供商工具，活动创作工具，改进的运动跟踪和远程治疗界面。这项努力将在随机对照试验中达到高潮，以调查VOTA的疗效，通过标准化评估评分的改善来衡量。商业机会：巴伦联合公司在迅速将这项技术商业化方面处于独特的地位。美国最大的康复医疗服务提供商HealthSouth的参与为在临床、家庭健康和远程治疗环境中引入VOTA治疗提供了一个跳板。
