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

描述（由申请人提供）：该项目的长期目标是为目前没有行动能力的人群提供独立的行动能力（这些人可能有动力行动能力，但有严重的上象限运动障碍，无法操作商用轮椅控制），这与NICHD的使命是一致的，即提供康复技术来增加行动能力，使身体残疾的人成为社区的积极成员。拟议项目的目的是建立矫正轮椅控制器（自我参考个人矫正全能控制接口，简称SPOOCI）的概念证明，该控制器将允许这些人群的功能性移动。开发SPOOCI的基本原理是：(1)将访问点从轮椅移动到用户的身体，以减少外部运动的影响；(2)提供一个“可穿戴”界面；(3)通过感知等距力而不是运动来简化运动任务；(4)消除在中线或中线附近保持位置的需要。我们的创新理念的特点是，控制传感器不是安装在轮椅框架上，而是通过定制的矫形器安装在相邻的近端身体上。目标1客观地确定患有严重上象限神经运动障碍且不能使用传统操纵杆驾驶电动轮椅的个体是否可以使用spoci，以及在多大程度上可以驾驶电动轮椅。目标2评估功能性轮椅驾驶能力的水平，通过使用标准化的动力移动计划的SPOOCI实现。目的3结合定性访谈方法来检查用户和护理人员的经验，态度和信念，关于使用SPOOCI。这个项目将包括一个开发和实验阶段。开发阶段将包括概念和细节设计、原型设计、台架评估和反复修订的标准顺序，从而形成新的PW控制系统的测试版原型，该系统安全且适合于预期用户群体的测试。在实验阶段，将收集试点数据以解决上述第一到第三个目标。将为五位参与者中的每一位创建一个图形配置文件，其中包括每周的性能结果（速度、准确性和Fitts常数）数据以及功能驾驶前和功能驾驶后的分数。绩效结果测量将与功能驱动能力分数相关联，以确定绩效测量在什么程度上转化为功能。定性方法将用于检查用户和护理人员的经验，态度和信念。

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.
