 DESCRIPTION (provided by applicant): Abstract Impact of Equipment Purchase on VA funded research. Recovery of walking function is one of the highest priorities of neurological rehabilitation. For over ten years, the Brain Rehabilitation Research Center (BRRC) has been the epicenter of VA-funded research into the mechanism and recovery of walking function at the Malcom Randall VA Medical Center. Most of this research was accomplished in the BRRC's Human Motor Performance Lab (HMPL) using instrumented treadmills that measure biomechanical features of gait. However, definitive research from our own investigations and others in the field now demonstrates that treadmill walking is an inadequate surrogate for quantifying the true impairments and/or recovery of everyday walking, which occurs overground. In order for the Malcom Randall VA Medical Center to remain at the forefront of walking rehabilitation research, it is essential that we have the capability to accurately measure the biomechanics of overground walking. This capability will greatly enhance our ability to compete for grant funding, and thereby advance the science of recovery for neurologically injured Veterans. Proposal Objective: Purchase and install the Optima HPS force platforms in the Human Motor Performance Lab, for shared use. The Optima HPS will enable us to measure the three- dimensional biomechanics of overground walking. These force platforms will be used extensively by the six full-time research investigators, and expected new investigators that comprise the BRRC's Locomotor Research Initiative. Additional expected users are VA colleagues inside and outside of the BRRC and UF colleagues in the Departments of Neurology, Physical Therapy, Aging and Geriatric Research, Biomedical Engineering, and Applied Physiology/Kinesiology. Equipment Description. The requested equipment is the Optima Human Performance System (HPS), an array of force-platforms for gait kinetic data acquisition during overground walking, manufactured by Advanced Mechanical Technology, Inc. (AMTI). Mounting rails and installation service (both provided by AMTI) are included in this request because they are necessary for providing a sufficiently flat and rigid mounting surface and precision calibration. An Optima HPS force platform contains the following: signal conditioner, 9 meters of cabling, resin kit, and mounting hardware. The system has the capacity to measure a maximum vertical force of 2000lb (8900N) and a maximum lateral force of 1000lb (4450N), maximum thresholds required to measure GRF's during human locomotion and balance activities. Six signals are measured by the platform (force and moment X, Y and Z components. Administration and Usage. The National VA, RR&D, Brain Rehabilitation Research Center of Excellence (BRRC) will house the equipment in its Human Motor Performance Laboratory (HMPL), where it has successfully maintained and equitably managed the use of its research equipment for the past decade for shared used among VA investigators. The Medical Center is solidly in support of the BRRC and its research, most especially its shared equipment and laboratory resources.

 描述(由申请人提供)： 摘要设备采购对退伍军人管理局资助研究的影响。步行功能的恢复是神经康复的首要任务之一。十多年来，脑康复研究中心(BRRC)一直是由退伍军人管理局资助的马尔科姆·兰德尔医学中心步行功能机制和恢复研究的中心。这项研究的大部分是在BRRC的人类运动性能实验室(HMPL)使用测量步态生物力学特征的仪表式跑步机完成的。然而，来自我们自己和该领域其他研究人员的权威研究现在表明，跑步机步行不足以量化日常步行的真实损害和/或恢复，这种情况发生在地面上。为了让马尔科姆·兰德尔退伍军人医学中心保持在步行康复研究的前沿，我们有能力准确地测量地面行走的生物力学是至关重要的。这一能力将极大地增强我们竞争赠款资金的能力，从而促进神经损伤退伍军人的康复科学。提案目标：在人体运动性能实验室购买并安装Optima HPS测力平台，供共享使用。Optima HPS将使我们能够测量地面行走的三维生物力学。这些力量平台将被六名全职研究调查人员广泛使用，并预计将有新的调查人员组成BRRC的运动研究倡议。其他预期用户包括BRRC内外的VA同事以及UF神经病学、物理疗法、衰老和老年研究、生物医学工程和应用生理学/运动学系的同事。设备描述。所要求的设备是由先进机械技术公司(AMTI)制造的Optima Human Performance System(HPS)，这是一个用于地面行走过程中步态动力学数据采集的力平台阵列。安装导轨和安装服务(均由AMTI提供)包括在本申请中，因为它们是提供足够平坦和坚硬的安装表面和精密校准所必需的。Optima HPS测力平台包含以下内容：信号调节器、9米长的电缆、树脂套件和安装硬件。该系统具有测量最大垂直力2000磅(8900N)和最大侧向力1000磅(4450N)的能力，这是在人类运动和平衡活动中测量GRF所需的最大阈值。六个信号由平台(力和力矩X、Y和Z分量)测量。管理和使用。国家VA，RR&D，脑康复研究卓越中心(BRRC)将把设备存放在其人类运动性能实验室(HMPL)，在过去十年中，该中心成功地维护并公平地管理了其研究设备的使用，供VA研究人员共享使用。医学中心坚定地支持BRRC及其研究，尤其是其共享的设备和实验室资源。
