DESCRIPTION (provided by applicant): The proposed project creates and proves an innovative wheelchair accessory, SAFESLIDEBOARD. SAFESLIDEBOARD is superior to currently available transfer boards that require use of both hands for the following reasons: (1) SAFESLIDEBOARD is an attached component of the armrest reducing the risk for falls that occur when the standard transfer board slides off the wheelchair or transfer surface; (2) Transfers can be performed by individuals with limited hand use, weight shift, and cognitive awareness to set up and transfer independently; and (3) SAFESLIDEBOARD is vertically secured directly under a flip back armrest (developed in Phase I) instead of being stowed behind or on the lap of the wheelchair user and thus cannot be dropped or misplaced. The proposed project supports the mission of the National Institutes on Aging by developing/refining technology to address "Special problems and needs of the aged," particularly aged individuals with impaired mobility and hand use. The proposed Phase II project has a developmental phase, year 1, and an experimental phase, year 2. The Specific Aims are to: (1) Develop new prototypes of retrofitting armrest transfer board for wheelchairs; (2) Determine the effectiveness of SAFESLIDEBOARD; (3) Determine health care provider satisfaction with SAFESLIDEBOARD using qualitative, structured interview research techniques; and (4) Determine marketing options for SAFESLIDEBOARD. During the year 1, developmental phase, the Phase I prototype will be redesigned and fabricated to be lighter, stronger, and suitable for multiple wheelchairs - based on Phase I results. Aim 1 will complete seven tasks that include redesign of the: (1) transfer board model, (2) armrest adapter(arm assembly) to fit the new transfer board, (3) rear landing apparatus for flip-back armrest; (4) armrest tubing; (5) front attachment/seat cradle (6) connecting rod and swiveling hinge assembly; and (7) beta prototype production and ISO testing. During the year 2, experimental phase, clinical trials (N=72, 36 wheelchair users and 36 healthcare providers) will compare SAFESLIDEBOARD to the standard transfer board for bed, tub and toilet transfers. The target population is individuals post stroke but will not exclude other individuals who have difficulty using a standard transfer board. A mixed design approach will be used: (1) Prospective, repeated measures crossover (ABB, BAA, AAB, and BBA) for Aim 2; (2) Qualitative for Aim 3; and (3) Survey for Aim 4. Wheelchair user outcomes include: assistance required, safety, and features. Caregiver outcomes include: ease of installation, preference, pre-installed versus accessory, site of installation (right/left or both). Data will be analyzed using within subject repeated analyses, controlling for covariates, for Aim 2, and qualitative analyses based on grounded theory for Aim 3, and descriptive statistics for Aim 4, The projected Phase II end result is a market ready transfer device that passes ISO standards for a wheelchair armrest. PUBLIC HEALTH RELEVANCE: One of the single most important factors allowing older adult wheelchair users to stay at home, living independent of caregivers, and free of debilitating injury, is their ability to transfer to and from their wheelchairs safely. Transfer boards, which are boards upon which the user slides into and out of their wheelchair, are often misplaced, difficult to set up and free to slide off of the wheelchair to cause falls. The purpose of this project is to develop easily installed flip back armrests that can be lowered with one hand to be used as attached transfer boards that never fall or get misplaced.

描述（由申请人提供）：拟议的项目创建并证明了一个创新的轮椅配件，安全滑板。由于以下原因，SAFESLIDEBOARD上级目前可用的需要使用双手的转移板：（1）SAFESLIDEBOARD是扶手的附接部件，降低了当标准转移板滑离轮椅或转移表面时发生福尔斯的风险;（2）转移可由手部使用受限、重心转移、认知意识不强的个人独立进行设置和转移;以及（3）安全滑板直接垂直固定在翻转式扶手（在第一阶段开发）下面，而不是存放在轮椅使用者的后面或膝盖上，因此不会掉落或放错地方。拟议的项目支持国家老龄问题研究所的使命，开发/改进技术，以解决“老年人的特殊问题和需要”，特别是行动不便和用手不便的老年人。拟议的第二阶段项目有一个发展阶段，即第一年，和一个实验阶段，即第二年。具体目标是：（1）开发新的轮椅扶手转换板改装原型;（2）确定SAFESLIDEBOARD的有效性;（3）使用定性、结构化访谈研究技术确定医疗保健提供者对SAFESLIDEBOARD的满意度;（4）确定SAFESLIDEBOARD的营销方案。在第一年的开发阶段，第一阶段的原型将重新设计和制造更轻，更强，适合多个轮椅-基于第一阶段的结果。Aim 1将完成七项任务，包括重新设计：（1）转接板模型，（2）扶手适配器（臂组件），以适应新的转接板，（3）后翻式扶手的后着陆装置;（4）扶手管;（5）前附件/座椅支架;（6）连杆和旋转铰链组件;以及（7）beta原型生产和ISO测试。在第2年的实验阶段，临床试验（N=72，36名轮椅使用者和36名医疗保健提供者）将比较SAFESLIDEBOARD与床，浴缸和厕所转移的标准转移板。目标人群是中风后个体，但不排除其他难以使用标准转运板的个体。将使用混合设计方法：（1）目标2的前瞻性、重复测量交叉（ABB、BAA、AAB和BBA）;（2）目标3的定性;和（3）目标4的调查。轮椅使用者的结果包括：所需协助、安全性和功能。护理人员的结果包括：易于安装、偏好、预安装与附件、安装部位（右/左或两者）。将使用受试者内重复分析、控制协变量（目标2）、基于扎根理论的定性分析（目标3）和描述性统计（目标4）对数据进行分析。预计的II期最终结果是通过ISO轮椅扶手标准的上市转移装置。 公共卫生关系：其中一个最重要的因素，使老年人轮椅使用者留在家里，生活独立的照顾者，并没有衰弱的伤害，是他们的能力，转移到和从他们的轮椅安全。转移板是使用者滑入和滑出其轮椅的板，其经常被放错位置，难以设置并且自由地滑出轮椅以导致福尔斯。这个项目的目的是开发易于安装的翻转扶手，可以用一只手降低，作为附加的转让板，永远不会下降或错位。
