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造成伤害的风险很高。 与工作有关的背痛和伤害是一种普遍的流行病，在很大程度上是由于 重复的患者处理活动，包括提升、转移和重新定位任务。床 椅子和椅子到厕所的转移一直是最具身体压力的 患者和护理人员需要完成的任务。发现机械转移辅助装置 降低护理人员受伤的风险。因此，美国（US）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升降机政策 直接与病人互动，以减少与工作有关的肌肉骨骼疾病的风险。 最常用的用于患者依赖性转移的移位技术包括 高架天花板升降机、落地吊索升降机和龙门式升降机。虽然这些设备允许 更安全地转移病人，他们这样做的缺点。架空吊索升降机需要大量的 安装可能不适合有结构缺陷或较低的房屋或建筑物 天花板基于地板的吊索升降机在护理人员的操作和易用性方面存在几个问题。 龙门式升降机由于其尺寸而非常难以移动和存放。研究表明 行动不便的人和护理人员都希望有新的动力设备， 更安全、更舒适、更独立的转移。 开发了AgileLife患者转移和移动系统（PTS）， 由Next Health LLC商业部署的是几种辅助技术的集成 这两个系统一起自动化了不能移动的个人往返医院病床的转移， 轮椅临时技术秘书处包括一张病床、一个一体化和可拆卸的 轮椅/马桶椅，对接系统，和一个转移“表”，移动个人， 还有床上然而，现有的临时警察部队并没有设计成可与一个电源一起工作， 轮椅 该项目的目标是反复设计、制作原型并测试改进的PTS 和第3组电动轮椅，以便PTS和电动轮椅兼容， 让更多身体残疾的人使用。这将是 通过与包括第3组在内的最终用户焦点组一起完善设计规范来完成 轮椅使用者和护理人员。然后开发一个原型并测试它的功能， 安全为代价的然后将通过让第3组轮椅使用者和护理人员进行用户测试 两人一组试用原型并完成可用性调查问卷。理疗师也会评估 用户测试期间传输的安全性。
