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）：脊髓损伤后保留上肢功能的 PVA 临床实践指南建议轮椅使用者尽量减少完成上肢任务所需的力量，避免将手放在肩膀上方，并避免肩部内旋的极端位置和绑架。使用轮椅的几个方面都会导致这些情况。由于轮椅使用者是坐着的，他们抓握或处理的许多物体都高于肩膀，例如洗碗或从杂货店货架上拿东西。一些电动轮椅配有电动座椅升降机，可用于提升轮椅使用者。然而，没有提供座椅升降功能的手动轮椅。往返轮椅通常会导致肩部内旋和外展，从而支撑使用者体重的很大一部分。转运板可用于显着减少转运过程中的体力需求。然而，转移板不太便携，因此通常不会在轮椅上携带。因此，当用户需要转接板时，转接板并不总是可用。 ErgoChair 智能手动轮椅解决了举重任务和转移过程中肩部人体工程学不佳的问题。 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，座椅下方还藏有一块轻型转移板。用户可以创建预设座椅高度，使他们能够快速将座椅设置到他们想要的位置。该项目将涉及：1) 开发概念验证原型并评估其有效性，2) 根据焦点小组反馈和工程探索完善设计，3) 通过重复测量生物力学研究量化 ErgoChair 的人体工程学优势。该项目的结果是，轮椅使用者在日常任务中将能够大大减少上肢的体力需求。 ErgoChair 智能手动轮椅与公共卫生的相关性 手动轮椅使用者发生上肢过度使用损伤的风险相当大。一项预防措施是减少使用轮椅期间的身体需求。该项目将开发创新技术，显着改善轮椅转移和举升任务的人体工程学。
