DESCRIPTION (provided by applicant): Current Medicare policy unnecessarily limits the mobility of the frail elderly by funding purchases of inappropriate manual wheelchairs. The long term, far reaching goal of this research proposal is to alter Medicare policy such that the mobility of the frail elderly is improved through purchases of ultralight manual wheelchairs and/or power wheelchairs. Specifically, we are investigating the effect of rear axle position, wheelchair weight, and surface rolling resistance on the biomechanics of wheelchair propulsion in the frail and non-frail elderly. Elderly frail and non frail individuals, as defined by the presence of 3 of 5 criteria, will propel in four wheelchair configurations (2 axle positions and 2 weight conditions) across four surfaces with increasing varied rolling resistance. Participants will also complete a six minute wheel and isometric wheelchair push as measures of functional performance. Outcome variables of interest include cadence, self-selected velocity, RPE, resultant force, effective force, maximal force (isometric test), and total distance traveled (6 min. wheel). In general we hypothesize that frail elderly individuals will have larger differences in propulsion biomechanics in response to the different wheelchair configurations than the non-frail group.

描述（由申请人提供）：目前的医疗保险政策通过资助购买不适当的手动轮椅，不必要地限制了体弱老年人的行动能力。这项研究提案的长期、深远目标是改变医疗保险政策，通过购买超轻型手动轮椅和/或电动轮椅来改善体弱老年人的行动能力。具体而言，我们正在调查的效果，后轴位置，轮椅重量，和表面滚动阻力轮椅推进的生物力学在体弱和非体弱老人。根据5项标准中的3项标准定义的年老体弱和非体弱个体，将在四种轮椅配置（2个轴位置和2个重量条件）中通过四个表面推进，并增加不同的滚动阻力。参与者还将完成一个六分钟的轮子和等距轮椅推动作为功能性能的措施。感兴趣的结果变量包括步频、自选速度、RPE、合力、有效力、最大力（等长测试）和行进的总距离（6分钟轮）。在一般情况下，我们假设，体弱的老年人将有更大的差异，在推进生物力学响应不同的轮椅配置比非体弱组。
