SPOOCI: Self-Referenced Personal Omni-Purpose Orthotic Control Interface

说明(由申请者提供)：该项目的长期目标--为目前没有行动能力的人(有能力行动能力的候选人，但上象限有严重的运动障碍，使他们无法操作商业轮椅控制装置的个人)提供独立行动能力--与NICHD的使命一致--提供康复技术，以增加行动能力，使身体残疾的人成为其社区的活跃成员。拟议项目的目的是建立一种矫形轮椅控制器(自我引用的个人矫形多功能控制接口，简称SPOOCI)的概念证明，将允许这一人群的功能活动。开发SPOOCI的基本原理是：(1)将接入点从轮椅移动到使用者的身体，以减少额外运动的影响；(2)提供“可穿戴”界面；(3)通过感应等长力而不是运动来简化运动任务；以及(4)消除将位置保持在中线或接近中线的需要。我们的创新概念的独特之处在于，控制传感器不是指向轮椅框架，而是通过定制的矫形器将其安装在相邻的近端身体部分。目标1客观地确定患有严重上象限神经运动障碍、不能使用传统操纵杆驾驶电动轮椅的人是否可以使用SPOOCI，以及使用SPOOCI的效果如何。目标2评估通过使用标准化动力移动计划的SPOOCI实现的功能轮椅驾驶能力的水平。目标3结合了定性访谈方法，以检查用户和照顾者关于使用SPOOCI的经验、态度和信念。该项目将包括开发和试验阶段。开发阶段将包括概念和详细设计、原型、工作台评估和反复修改的标准序列，从而产生新的PW控制系统的测试版原型，该原型是安全的，适合目标用户群进行测试。在试验阶段，将收集试点数据，以满足上述目标之一至三个目标。将为五名参与者中的每一位创建一个图形简档，其中将包括每周的性能结果(速度、精度和Fitts常量)数据以及功能驾驶前后的分数。绩效结果指标将与功能驾驶能力分数相关联，以确定在什么情况下绩效指标将转化为功能。定性方法将被用来检查使用者和照顾者的经历、态度和信念。 公共卫生相关性：研究表明，流动性、进入社区的机会和社会融合提高了生活质量。事实上，社会参与已被发现是比身体功能或受伤程度更重要的生活质量预测指标。该项目旨在为那些目前依赖他人的人提供独立的行动，以便他们能够参与社会并满足其日常需要。

DESCRIPTION (provided by applicant): The long term objective of this project -- provision of independent mobility to a population who currently has none (individuals who are candidates for power mobility but have severe motor impairments of the upper quadrants that prevent them from operating commercial wheelchair controls) -- is consistent with the mission of NICHD - to provide rehabilitation technology to increase mobility to allow those with physical disabilities to be active members of their communities. The purpose of the proposed project is to establish proof of concept of an orthotic wheelchair controller (Self-referenced Personal Orthotic Omni-purpose Control Interface abbreviated as SPOOCI)) that will allow functional mobility for this population. The rationale for developing SPOOCI is to: (1) Move the point of access from the wheelchair to the user's body to reduce the effect of extraneous movements, (2) Provide a "wearable" interface, (3) Simplify the motor task by sensing isometric force rather than movement, and (4) Eliminate the need to maintain a position at or near midline. Our innovative concept is distinguished by referencing the control sensor not to the wheelchair frame but mounting it instead on the adjacent proximal body segment via a custom-formed orthosis. Aim 1 objectively determines whether and how well individuals who with severe upper quadrant neuromotor impairment who cannot drive a power wheelchair with a traditional joystick can do so using a SPOOCI. Aim 2 evaluates the level of functional wheelchair driving competence achieved through the use of SPOOCI using the standardized Powered Mobility Program. Aim 3 incorporates qualitative interview methods to examine user and caregiver experiences, attitudes, and beliefs regarding the use of SPOOCI. This project will comprise a development and experimental phase. The developmental phase will incorporate the standard sequence of conceptual and detail design, prototyping, bench evaluation, and repeated revision, leading to a beta prototype of a new PW control system which is safe and suitable for testing by the intended user population. During the experimental phase, pilot data will be collected to address aims one through three above. A graphic profile will be created for each of the five participants that will include weekly performance outcomes (speed, accuracy, and Fitts constant) data and pre and post functional driving scores. Performance outcome measures will be correlated with functional driving competence scores to determine at what point performance measures translate to funtion. Qualitative methods will be used to examine user and caregiver experiences, attitudes, and beliefs. PUBLIC HEALTH RELEVANCE: Research suggests mobility, access to the community, and social integration enhance quality of life. In fact, social participation has been found to be a more important predictor of quality of life than physical functioning or extent of injury. This project seeks to provide independent mobility to those who presently are dependent upon others, so that they may participate in society and meet their daily needs.
