DESCRIPTION (provided by applicant): The PVA clinical practice guidelines for preserving upper limb function following spinal cord injury recommends that wheelchair users minimize the force required to complete upper limb tasks, avoid positioning the hand above the shoulder and avoid extreme positions of shoulder internal rotation and abduction. There are several aspects of wheelchair use that lead to these conditions. Because wheelchair users are seated, many of the objects they grab or work with are above the level of their shoulder, such as washing dishes or getting items off the grocery store shelf. Some powered wheelchairs have an electric seat elevator that can be used to raise the wheelchair user up. However, there are no manual wheelchairs that offer a seat-elevating feature. Transfers to and from the wheelchair commonly lead to an internally- rotated and abducted shoulder that is supporting a large percentage of the user's body weight. Transfer boards can be used to dramatically reduce physical demand during transfers. However, transfer boards are not very portable, so they are not typically carried on the wheelchair. As a result, transfer boards are not always available when the user needs one. The ErgoChair Smart Manual Wheelchair is a solution to the problem of poor shoulder ergonomics during lifting tasks and transfers. The ErgoChair allows the seat height of a manual wheelchair to be set by the user much like setting the height of an office chair. In addition, there is a lightweight transfer board stowed under the seat. Users can create preset seat heights, allowing them to quickly set the seat to exactly where they want it. This project will involve: 1) developing a proof-of concept prototype and evaluating its effectiveness, 2) refining the design based on focus group feedback and engineering exploration and 3) quantifying the ergonomic benefits of the ErgoChair through a repeated measures biomechanical study. As a result of this project, wheelchair users will be able to dramatically reduce physical demand on their upper limbs during everyday tasks. ErgoChair Smart Manual Wheelchair Relevance to Public Health Manual wheelchair users are at considerable risk of developing upper limb overuse injuries. One preventative measure is to reduce physical demand during wheelchair use. This project will develop innovative technology that will dramatically improve the ergonomics of wheelchair transfers and lifting tasks.

描述（由申请人提供）：脊髓损伤后保存上肢功能的PVA临床实践指南建议轮椅使用者最大程度地减少完成上肢任务所需的力量，避免将手放在肩膀上方，避免肩部内部旋转和埋葬的极端位置。轮椅使用的几个方面导致了这些条件。由于轮椅使用者坐在座位上，他们抓住或使用的许多物体都超过了肩膀的水平，例如洗碗或从杂货店架子上拿出物品。一些电动轮椅设有电动座椅电梯，可用于将轮椅用户抬高。但是，没有手动轮椅可提供座椅高度的功能。转移到轮椅上通常会导致内部旋转和绑架的肩膀，该肩膀支持大部分用户体重。转移板可用于大大减少转移期间的身体需求。但是，转移板不是很便携，因此通常不会坐在轮椅上。结果，当用户需要一个时，转移板并不总是可用的。 Ergochair智能手动轮椅是解决任务和转移期间肩部人体工程学差的问题的解决方案。 Ergochair允许用户设置手动轮椅的座椅高度，就像设置办公椅的高度一样。此外，座椅下方还有一个轻巧的转移板。用户可以创建预设的座椅高度，从而使他们能够快速将座椅设置为完全想要的位置。该项目将涉及：1）制定概念验证原型并评估其有效性，2）基于焦点小组反馈和工程探索的设计，以及3）通过重复测量的生物力学研究来量化Ergochair的人体工程学益处。由于这个项目，轮椅用户将能够在日常任务中大大减少上肢的身体需求。 Ergochair智能手动轮椅与公共卫生手动轮椅使用者的相关性有很大的风险出现上肢过度伤害。一种预防措施是减少轮椅使用期间的身体需求。该项目将开发创新的技术，该技术将大大改善轮椅转移和提起任务的人体工程学。
