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（由申请人提供）：该项目的长期目标 - 向目前没有的人群提供独立的流动能力（个人是候选功率流动性，但具有严重的上象限的障碍，这些象限阻止了他们无法操作商业轮椅控制的人 - 与NICHD的任务一致 - 与康复技术相一致，以增加康复能力，以使其具有无效的成员的康复能力。拟议项目的目的是建立矫形轮椅控制器的概念证明（自我引用的个人矫形器Omni-Purpose控制界面缩写为Spooci））），该界面将允许该人群的功能性移动性。开发SPOOCI的理由是：（1）将通道从轮椅移到用户的身体以减少外部运动的效果，（2）提供“可穿戴”界面，（3）通过感应等距力而不是运动来简化运动任务，并且（4）消除在中线或接近中线的位置。我们的创新概念是通过将控制传感器引用到轮椅框架而是通过定制形成的矫形器将其安装在相邻的近端身体细分市场上来区分。 AIM 1客观地确定患有严重的上象限神经运动障碍的个人是否能用传统的操纵杆驾驶动力轮椅可以使用Spooci来做到这一点。 AIM 2评估通过使用标准化动力移动计划使用SPOOCI实现的功能轮椅驱动能力的水平。 AIM 3结合了定性访谈方法，以检查对使用Spooci的用户和照顾者的经历，态度和信念。该项目将构成开发和实验阶段。发展阶段将结合概念和细节设计，原型设计，台式评估和重复修订的标准顺序，从而导致新的PW控制系统的beta原型，该系统安全且适合于预期的用户群体测试。在实验阶段，将收集试点数据，以解决上面的目标一到三。将为五个参与者中的每个参与者中的每个参与者创建图形概况，其中包括每周的性能结果（速度，准确性和fitts常数）以及功能驾驶得分和后驾驶得分。性能结果度量将与功能驱动能力得分相关，以确定在什么点绩效指标转化为功能。定性方法将用于检查用户和照顾者的经验，态度和信念。 公共卫生相关性：研究表明流动性，进入社区以及社会融合可以提高生活质量。实际上，已经发现社会参与是生活质量比身体机能或伤害程度更重要的预测指标。该项目旨在为目前依赖他人的人提供独立的流动性，以便他们可以参与社会并满足他们的日常需求。
