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.

描述（申请人提供）：该项目的长期目标是为目前没有独立流动能力的人口提供独立流动能力。（个人谁是候选人的权力流动，但有严重的运动障碍的上象限，使他们无法操作商业轮椅控制）-是一致的使命的NICHD -提供康复技术以增加行动能力，让身体残疾者成为社区的积极成员。拟议项目的目的是建立一个矫正轮椅控制器（自我参考个人矫正多用途控制界面，缩写为SPOOCI）的概念证明，这将使该人群的功能移动。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“可穿戴”界面，（3）通过感测等长力而不是运动来简化运动任务，以及（4）消除在中线或中线附近保持位置的需要。我们的创新概念的特点是控制传感器不参考轮椅框架，而是通过定制的矫形器将其安装在相邻的近端身体部分。目的1客观地确定是否以及如何与严重的上象限神经运动障碍的人谁不能用传统的操纵杆驱动电动轮椅可以这样做，使用SPOOCI。目的2评估通过使用SPOOCI标准化动力移动程序实现的功能性轮椅驾驶能力的水平。目标3采用定性访谈方法，以检查用户和护理人员的经验，态度和信念，关于使用SPOOCI。该项目将包括一个开发和试验阶段。开发阶段将包括概念和详细设计、原型制作、台架评估和重复修订的标准顺序，从而形成新PW控制系统的beta原型，该原型安全且适合预期用户人群进行测试。在实验阶段，将收集试点数据以实现上述目标一到三。将为五名参与者中的每一位创建图形配置文件，其中包括每周性能结果（速度、准确性和拟合常数）数据以及术前和术后功能驾驶评分。性能结果测量将与功能驾驶能力分数相关，以确定性能测量在什么时候转化为功能。定性方法将用于检查用户和护理人员的经验，态度和信念。 公共卫生相关性：研究表明，流动性，进入社区和社会融合可以提高生活质量。事实上，社会参与被认为是比身体功能或受伤程度更重要的生活质量预测因素。该项目旨在为那些目前依赖他人的人提供独立的流动性，使他们能够参与社会并满足日常需要。
