All manual lifting and repositioning techniques have a high-risk for injury to caregivers. Work-related back pain and injuries are a widespread epidemic and due in large part to repeated patient handling activities, including lifting, transferring, and repositioning tasks. Bed to chair and chair to toilet transfers are consistently ranked among the most physically stressful tasks required of patients and caregivers. Mechanical transfer assist devices were found to reduce the risk of injury to caregivers. Consequently, the United States (US) government passed a bill in 2006 requiring all hospitals to establish a no manual lift policy for staff members who interact directly with patients to reduce the risk of work-related musculoskeletal disorders. The most commonly used lift technologies for dependent transfers of patients include the overhead ceiling lift, the floor-based sling lift, and the Gantry lift. While these devices allow for safer transfer of patients, they do so with shortcomings. Overhead sling lifts require extensive installation that may not be suitable for homes or buildings with structural deficiencies or a low ceiling. Floor-based sling lifts have several issues with caregiver manipulation and ease of use. Gantry lifts are very difficult to move and store due to their size. Research has demonstrated that people with mobility impairments and caregivers both desire new, powered devices for safer and more comfortable and independent transfers. The AgileLife Patient Transfer and Movement System (PTS) developed and commercially deployed by Next Health LLC is an integration of several assistive technologies that together automate the transfer of immobile individuals to and from a hospital bed and a wheelchair. The PTS includes a hospital bed, an integrated and detachable wheelchair/commode chair, a docking system, and a transfer ‘sheet’ that moves the individual to and from the bed. However, the existing PTS has not been designed to work with a power wheelchair. The goals of this project will be to iteratively design, prototype and test a modified PTS and group 3 power wheelchair so that the PTS and power wheelchairs could be compatible, allowing it to be used by a greater number of people with physical disabilities. This will be accomplished by refining design specifications with a focus group of end user including group 3 wheelchair users and caregivers. Then developing a prototype and testing it for functionality and safety. User testing will then be conducted by having group 3 wheelchair users and caregiver pairs trial the prototype and complete usability questionnaires. A physical therapist will also rate the safety of the transfers during the user testing.

所有手动提升和重新定位技术对护理人员的伤害具有高风险。 与工作有关的背痛和受伤是一种广泛的流行病，很大程度上是由于 重复的患者处理活动，包括举重，转移和重新定位任务。床 椅子和厕所转移的椅子始终被排名最大的压力最大 患者和看护人所需的任务。发现机械转移辅助设备 降低受伤者受伤的风险。因此，美国（美国）政府 2006年通过了一项法案，要求所有医院为工作人员制定无手动提升政策 他们直接与患者互动，以降低与工作有关的肌肉骨骼疾病的风险。 针对患者依赖转移的最常用的升力技术包括 顶部天花板升降机，基于地板的吊索升降机和龙门升降机。这些设备允许 患者的更安全转移，他们会出现缺点。高架吊带升降机需要广泛 安装可能不适合具有结构性缺陷或低矮的房屋或建筑物 天花板。基于地板的吊带升降机在护理人员的操纵和易用性方面有几个问题。 龙门式升降机由于尺寸而难以移动和存放。研究表明 流动性障碍和看护人的人都希望新的，有能力的设备 更安全，更舒适，更独立的转移。 AgileLife的患者转移和运动系统（PTS）开发了 Next Health LLC在商业上部署的是多种辅助技术的集成 这共同使固定的个体转移到医院的病床和一个 轮椅。 PTS包括一张医院床，一张综合且可拆卸的 轮椅/马桶椅，一个对接系统和一个将个人移至的“床单” 从床上。但是，现有的PTS尚未设计为具有力量 轮椅。 该项目的目标是迭代设计，原型和测试修改的PTS 和第3组动力轮椅，以便PT和电动轮椅可以兼容， 允许更多的身体残疾人使用它。这将是 通过与最终用户的焦点组完善设计规格来完成，包括第3组 轮椅使用者和护理人员。然后开发原型并测试其功能和 安全。然后，将通过3轮轮椅用户和护理人员来进行用户测试 配对试用原型和完整的可用性问卷。物理治疗师也会对 用户测试期间转移的安全性。
