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(申请人提供)：建议项目创造并证明了一种创新的轮椅配件SAFESLIDEBOARD。SAFESLIDEBOARD优于目前提供的需要双手使用的转接板，原因如下：(1)SAFESLIDEBOARD是扶手的一个附加组件，可降低标准转接板滑出轮椅或转接面时发生跌倒的风险；(2)转接器可以由手使用有限、体重转移和认知意识独立设置和转接器的个人执行；以及(3)SAFESLIDEBOARD直接垂直固定在翻转靠背扶手下(第一阶段开发)，而不是存放在轮椅使用者的背后或腿上，因此不能掉落或错放。拟议的项目通过开发/改进技术来支持国家老龄问题研究所的使命，以解决“老年人的特殊问题和需求”，特别是行动不便和手部使用障碍的老年人。拟议的第二阶段项目包括第一年的开发阶段和第二年的试验阶段。具体目标是：(1)开发轮椅扶手转移板的新原型；(2)确定SAFESLIDEBOARD的有效性；(3)使用定性的、结构化的访谈研究技术确定医疗保健提供者对SAFESLIDEBOARD的满意度；以及(4)确定SAFESLIDEBOARD的营销选择。在第一年的开发阶段，第一阶段的原型将根据第一阶段的结果重新设计和制造，以使其更轻、更坚固，并适用于多种轮椅。AIM 1将完成七项任务，包括：(1)转接板模型，(2)扶手适配器(扶手组件)，以适应新的转接板，(3)用于翻转后扶手的后部着陆装置，(4)扶手管材，(5)前附件/座椅托架(6)连杆和旋转铰链组件，以及(7)测试版原型生产和ISO测试。在第二年的实验阶段，临床试验(N=72，36名轮椅使用者和36名医疗保健提供者)将对SAFESLIDEBOARD与床、浴缸和厕所转移的标准转移板进行比较。目标人群是中风后的个人，但不会排除使用标准转移板有困难的其他个人。将使用混合设计方法：(1)目标2的预期、重复测量交叉(ABB、BAA、AAB和BBA)；(2)目标3的定性；以及(3)目标4的调查。轮椅使用者的结果包括：所需的辅助、安全性和特性。护理者的结果包括：安装的简易性、首选项、预装还是附件、安装位置(右/左或两者)。将使用目标2的对象内重复分析、协变量控制、目标3的基于扎根理论的定性分析和目标4的描述性统计对数据进行分析，预计第二阶段的最终结果是通过ISO标准的轮椅扶手的市场准备转移装置。 与公共健康相关：允许老年人轮椅使用者呆在家里、独立于照顾者生活、不受损害的最重要因素之一是他们安全地往返轮椅的能力。转接板是使用者在其上滑入和滑出轮椅的板，经常被放错位置，难以设置，并且可以自由滑出轮椅而导致摔倒。这个项目的目的是开发易于安装的翻转后扶手，可以用一只手放下，用作连接的传送板，永远不会摔倒或放错地方。
