DESCRIPTION (provided by applicant): Wheelchair Drive System Over half of the wheelchair user population has developed upper extremity (UE) pain and injury. One of the activities that likely contribute to the development of injury is wheelchair propulsion. A number of technologies have been developed to address this issue including ergonomic pushrims, geared hub wheels, lever drives and pushrim-activated power assist wheels. While the non-powered technologies have been shown to incrementally reduce demand on the UE, power assist wheels can practically eliminate the demand. However, it is not reasonable to use power assist wheels when powered off due to their considerable weight. In essence, they are powered wheelchairs with pushrim-mounted joysticks. There is a need to develop a light-weight removable power drive system for a manual wheelchair that can be used selectively by the individual to reduce UE demand during the course of everyday propulsion activities. This project will develop a wheelchair drive system to meet this need and evaluate its efficacy through a series of focus group assessments and a long-term use study. As a result of this project, wheelchair users will gain access to technology that will reduce UE demand and hopefully reduce their risk of developing overuse injuries. PUBLIC HEALTH RELEVANCE: Wheelchair Drive System Relevance to Public Health Manual wheelchair users are at considerable risk of developing upper limb overuse injuries. One preventative measure is to reduce demand on the upper extremities during propulsion. This project will develop a lightweight removable drive system that can be used to provide propulsion assistance, thereby reducing physical demand and the likelihood of developing overuse injuries.

描述（由申请人提供）：轮椅驱动系统超过一半的轮椅使用者人群患有上肢（UE）疼痛和损伤。可能导致损伤发展的活动之一是轮椅推进。已经开发了许多技术来解决这个问题，包括符合人体工程学的推缘、齿轮轮毂轮、杠杆驱动和推缘激活的动力辅助轮。虽然非动力技术已被证明可以逐步减少对UE的需求，但动力辅助车轮实际上可以消除需求。然而，由于其相当大的重量，在断电时使用动力辅助轮是不合理的。从本质上讲，它们是带有安装在推框上的电动轮椅。需要开发一种用于手动轮椅的轻质可拆卸动力驱动系统，其可以由个人选择性地使用，以减少日常推进活动过程中的UE需求。该项目将开发一种轮椅驱动系统，以满足这一需求，并通过一系列焦点小组评估和长期使用研究来评估其功效。由于这个项目，轮椅使用者将获得技术，这将减少UE的需求，并希望减少他们发展过度使用伤害的风险。 公共卫生相关性：轮椅驱动系统与公共卫生手册的相关性轮椅使用者有相当大的风险发展上肢过度使用损伤。一种预防措施是在推进过程中减少对上肢的需求。该项目将开发一种轻型可移动驱动系统，可用于提供推进辅助，从而减少物理需求和过度使用伤害的可能性。
