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患有上肢 (UE) 疼痛和损伤。可能导致损伤发生的活动之一是轮椅推进。为了解决这个问题，人们开发了多种技术，包括符合人体工程学的推轮、齿轮轮毂、杠杆驱动器和推轮驱动的助力轮。虽然无动力技术已被证明可以逐渐减少对 UE 的需求，但动力辅助轮实际上可以消除该需求。然而，由于助力轮重量相当大，在断电时使用助力轮是不合理的。本质上，它们是带有推轮安装操纵杆的动力轮椅。需要开发一种用于手动轮椅的轻型可拆卸动力驱动系统，该系统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来满足这一需求，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。通过该项目，轮椅使用者将获得能够减少 UE 需求的技术，并有望降低过度使用造成伤害的风险。 公共健康相关性：轮椅驱动系统与公共健康的相关性 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推进过程中对上肢的需求。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，从而减少体力需求和发生过度使用伤害的可能性。
