This Major Research Instrumentation award will enable engineers, clinical scientists, anthropologists, and other researchers to gain an understanding of how people walk and run. Studies of human walking and running and the associated forces that are placed on the body are central to solving critical problems in anatomically based design, injury risk and prevention, robotics development, and exoskeleton design. Yet coordinated and controlled studies of movement and forces are difficult. The purchase of a force-sensing treadmill will make such data collection possible at Virginia Tech and nearby schools such as the Edward Via College of Osteopathic Medicine, the Virginia Tech Carilion School of Medicine and Radford University. In conjunction with 3-D motion capture, the force-sensing treadmill will allow researchers to study how people from many populations produce force and power with their legs under multiple situations. It will allow for new studies in the following areas: (1) understanding the causes of lower-body musculoskeletal injury, (2) understanding changes in walking and running that result from lower-body disability or injury, (3) developing diagnostic and treatment algorithms to monitor and assess patient function following lower body injury and/or surgery, and (4) understanding how exoskeletons, feedback, and movement retraining can successfully rehabilitate the injured and improve mobility in the disabled. The research projects undertaken and interventions developed as a result of the treadmill will improve the prevention, diagnosis, and treatment of movement disorders. The team aims to characterize movement and loading asymmetry as well as energy exchange during various movement conditions in order to develop interventions to restore normal locomotion. A major goal is to identify compensatory movement patterns that are consistent across different populations, and develop ways of identifying these compensations in settings without a force-sensing treadmill. These insights will also be used to develop and evaluate novel low-power, active soft orthotics as a means of improving gait mechanics and minimizing pain. Exoskeletons will also be developed to provide increased capability and promote physical activity. The treadmill will be used to collect relevant biological signals during a wide range of activities, and combine the result with both neuromuscular and dynamics models. Finally, the treadmill will allow data collection on foot loading that will illuminate how foot shape and mechanics influence loading patterns and ultimately stress fractures. This project was supported by the Divisions of Civil, Mechanical and Manufacturing Innovation and Chemical, Bioengineering, Environmental and Transport Systems in the Directorate for Engineering.

这项重大研究仪器奖将使工程师，临床科学家，人类学家和其他研究人员能够了解人们如何走路和跑步。 人类行走和跑步以及施加在身体上的相关力的研究对于解决基于解剖学的设计，伤害风险和预防，机器人开发和外骨骼设计中的关键问题至关重要。然而，协调和控制的运动和力量的研究是困难的。 购买一台力传感跑步机将使弗吉尼亚理工大学和附近的学校，如爱德华维亚骨科医学院，弗吉尼亚理工大学卡耐基医学院和拉德福大学，这样的数据收集成为可能。 结合3D运动捕捉，力感跑步机将使研究人员能够研究来自许多人群的人如何在多种情况下用腿产生力和力量。 它将允许在以下领域进行新的研究：（1）了解下半身肌肉骨骼损伤的原因，（2）了解下半身残疾或损伤导致的行走和跑步的变化，（3）开发诊断和治疗算法，以监测和评估下半身损伤和/或手术后的患者功能，以及（4）了解外骨骼，反馈，和运动再训练可以成功地使受伤者康复，并改善残疾人的活动能力。 由于跑步机而进行的研究项目和开发的干预措施将改善运动障碍的预防，诊断和治疗。 该团队的目标是描述运动和负载不对称性以及各种运动条件下的能量交换，以开发恢复正常运动的干预措施。 一个主要的目标是确定补偿运动模式是一致的，在不同的人群，并制定确定这些补偿的设置没有一个力传感跑步机的方法。 这些见解也将用于开发和评估新型低功率主动软矫形器，作为改善步态力学和最大限度地减少疼痛的一种手段。 还将开发外骨骼，以提高能力并促进身体活动。 跑步机将用于在广泛的活动期间收集相关的生物信号，并将结果与神经肌肉和动力学模型联合收割机结合。 最后，跑步机将允许对足部负荷进行数据收集，这将阐明足部形状和力学如何影响负荷模式并最终影响应力性骨折。该项目得到了工程局土木、机械和制造创新司以及化学、生物工程、环境和运输系统司的支持。
