DESCRIPTION (provided by applicant): Using a wheelchair is physically demanding, as evidenced by overuse injuries of the upper extremity in over half of the wheelchair user population. Movement of a manual wheelchair, whether forward propulsion, turning, or deceleration, is achieved through use of the handrim. Previous improved handrim designs decrease the force required to propel the wheelchair, but sacrifice braking performance. This project will develop the GripRim, an innovative ergonomic wheelchair handrim designed to make manual wheelchair propulsion less physically demanding and more comfortable for the user, without compromising braking ability. The GripRim creates an increased frictional coefficient between the hand and the handrim, reducing the amount of force required to propel the wheelchair. The cross-sectional shape of the GripRim is contoured to match the shape of the hand, minimizing peak hand pressure during propulsion thereby increasing user comfort. Improvements in propulsion and braking performance will be proven through biomechanical evaluations of the GripRim. GripRim comfort will be confirmed through user evaluations. The GripRim will benefit manual wheelchair users by preserving upper extremity function and enhancing their mobility experience. PROPOSED COMMERCIAL APPLICATION: The proposed wheelchair handrim will potentially enhance the lives of all manual wheelchair users by making propulsion more comfortable and less physically demanding. The GripRim will interface to most wheelchair wheels and be sold as a standard wheelchair component or as an optional accessory.

描述（由申请人提供）：使用轮椅对体力要求很高，超过一半的轮椅使用者上肢过度使用损伤就证明了这一点。手动轮椅的运动，无论是向前推进、转动还是减速，都是通过使用手柄来实现的。先前改进的手轮设计减少了推动轮椅所需的力，但牺牲了制动性能。该项目将开发 GripRim，这是一种创新的符合人体工程学的轮椅扶手，旨在降低手动轮椅推进对体力的要求，让用户更加舒适，同时又不影响制动能力。 GripRim 增加了手和手轮之间的摩擦系数，从而减少了推动轮椅所需的力量。 GripRim 的横截面形状与手部形状相匹配，最大限度地减少推进过程中手部压力峰值，从而提高用户舒适度。推进和制动性能的改进将通过 GripRim 的生物力学评估得到证明。 GripRim 的舒适度将通过用户评价来确认。 GripRim 将通过保留上肢功能并增强他们的移动体验来使手动轮椅使用者受益。 拟议的商业应用： 拟议的轮椅扶手将通过使推进更舒适且对体力的要求更低，从而潜在地改善所有手动轮椅使用者的生活。 GripRim 将与大多数轮椅轮子连接，并作为标准轮椅组件或可选配件出售。
