Motion Capture System

描述(由申请人提供)：目前的申请寻求资金(231,783.00美元)，以升级目前在人类运动和平衡实验室(HMBL)，一个步态实验室，设在匹兹堡大学生物工程系的VICON运动捕捉系统。现有的动作捕捉系统正在失败。该实验室的主要长期研究目标是改善老年人的行动能力，降低跌倒的风险。使用该仪器的用户的其他研究兴趣包括上肢生物力学、膝盖生物力学、孕妇姿势控制研究和职业性跌倒。HMBL已被许多学科的研究人员使用，并拥有广泛的专业知识，包括老年病学家、神经学家、成像专家、精神病学家、物理治疗师、职业治疗师、统计学家、工程师和机器人专家。这些用户在匹兹堡大学、卡内基梅隆大学和密歇根大学的不同学校有预约。HMBL的具体目标是继续提供可用于运动和姿势控制研究的最先进的运动捕捉设施。HMBL目前由Rakii Cham博士和Mark Redfern博士执导。HMBL设施的日常运作由研究协调员兼实验室经理阿普丽尔·钱伯斯管理。随着动作捕捉系统的可能升级，从而进一步扩大对该设施的使用，将成立一个内部咨询委员会，以协助实验室主任监督该设施的管理。总而言之，HMBL设施是许多目前得到资助的和未来可能的研究人员使用的共享资源，其运动字幕系统的升级对于成功完成他们正在进行的和计划的研究项目至关重要。 与公共健康相关：目前的应用程序正在寻求资金，以升级匹兹堡大学在平衡和行走研究中使用的运动捕捉系统。这项研究的主要长期目标是改善老年人的行动能力，并将他们跌倒的风险降至最低。运动捕捉系统是许多具有广泛专业知识的研究人员(临床医生、工程师、数学家和机器人专家)所需要的，他们都对人体运动研究感兴趣，大多数用户专注于老年平衡/步态研究。其他研究兴趣包括与肌肉骨骼损伤风险相关的上肢和下肢生物力学，怀孕对步态和平衡的影响，以及地板支撑表面对疲劳的影响。

DESCRIPTION (provided by applicant): The current application seeks funding ($231,783.00) to upgrade a VICON motion capture system currently available in the Human Movement and Balance Laboratory (HMBL), a gait laboratory housed in the Department of Bioengineering at the University of Pittsburgh. The existing motion capture system is failing. The major long-term research goals of this laboratory are to improve mobility and to reduce the risk of falls in older adults. Other research interests of users using this instrumentation include upper extremity biomechanics, knee biomechanics, postural control research in pregnant women and occupational falls. HMBL has been used by investigators from many disciplines and with a wide range of expertise including geriatricians, neurologists, imaging experts, psychiatrists, physical therapists, occupational therapists, statisticians, engineers and roboticists. These users have appointments in various schools at the University of Pittsburgh, Carnegie Mellon University and the University of Michigan. The specific objective of the HMBL is to continue to provide a state-of-the art motion capture facility that can be used in movement and postural control research. HMBL is currently directed by Rakii Cham, PhD and Mark Redfern, PhD. The day-to-day operations of the HMBL facility are managed by April Chambers, M.S., a research coordinator and laboratory manager. With the potential upgrade of the motion capture system and thus further expanded use of the facility, an internal advisory committee will be formed to assist the laboratory directors in overseeing the management of the facility. In summary, the HMBL facility is a shared resource used by many currently funded and potential future investigators and the upgrade of its motion caption system is critical to the successful completion of their active and planned research projects. PUBLIC HEALTH RELEVANCE: The current application seeks funding to upgrade a motion capture system used in balance and walking research at the University of Pittsburgh. The major long-term goal of this research is to improve mobility in older adults and to minimize their risk of falls. The motion capture system is needed by many investigators with a wide range of expertise (clinicians, engineers, mathematicians and roboticists), all interested in human movement studies with the majority of users having a focus on geriatric balance/gait research. Other research interests include upper and lower extremity biomechanics related to the risk of musculoskeletal injuries, impact of pregnancy on gait and balance and influence of flooring support surfaces on fatigue.
