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）：当前的医疗保险政策不必要地通过资金购买不适当的手动轮椅来限制脆弱的老年人的流动性。这项研究建议的长期目标是改变医疗保险政策，以便通过购买超轻手动轮椅和/或电动轮椅来改善脆弱的老年人的流动性。具体而言，我们正在研究后桥位置，轮椅重量和表面滚动阻力对脆弱和非毛线老年人轮椅推进的生物力学的影响。由5个标准中的3个存在定义的老年脆弱和非脆弱的个体将在四个轮椅构型（2个轴位置和2个重量条件）中推进四个表面，并且滚动电阻的增加。参与者还将完成六分钟的轮毂和等轴轮椅推动，作为功能性能的度量。感兴趣的结果变量包括节奏，自选择的速度，RPE，导致力，有效力，最大力（等距测试）和总距离（6分钟车轮）。通常，我们假设脆弱的老年人在推进生物力学方面的差异将对不同的轮椅构型的构造较大。
