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(申请人提供)：使用轮椅对身体要求很高，超过一半的轮椅使用者上肢过度受伤就是明证。手动轮椅的移动，无论是向前推进、转向还是减速，都是通过使用扶手来实现的。以前改进的扶手设计降低了推动轮椅所需的力，但牺牲了制动性能。该项目将开发GrigRim，这是一种创新的符合人体工程学的轮椅手环，旨在使手动轮椅推进对身体的要求更低，对用户来说更舒适，而不会影响刹车能力。GrigRim增加了手和手环之间的摩擦系数，减少了推动轮椅所需的作用力。GrigRim的横截面形状与手的形状相匹配，最大限度地减少了推进过程中的最大手压，从而增加了用户的舒适性。推进和制动性能的改进将通过对GrigRim的生物力学评估来证明。GrigRim舒适性将通过用户评估得到确认。GrigRim将通过保留上肢功能和增强他们的移动体验而使手动轮椅用户受益。 建议的商业应用： 拟议的轮椅扶手将使推进更舒适，对身体的要求更低，从而潜在地改善所有手动轮椅使用者的生活。GrigRim将与大多数轮椅轮子接口，并作为标准轮椅组件或可选配件出售。
