Abstract

The purpose of this study was to design and develop an instrumentation configuration suitable for determining upper extremity forces during walker-assisted gait. To accomplish these goals a finite element model of a conventional aluminum tube walker was constructed and the structural cross-talk in frame members was fully described for orthogonal loading conditions. Results from the study were used to locate strain gage sensors on the structure such that independent measurements of unilateral hand loads could be determined. The instrumentation configuration is presented along with calibration data illustrating system output. Complete description of upper extremity kinetics during walker-assisted gait may provide insight into rehabilitative treatment strategies. Characterization of the demands placed upon the upper extremities and assessment of patient stability may influence walker design parameters (height, width, weight) and recommended procedures for use (foot placement, hand location, motion sequence, and feedback loading control).

一种测量单侧手部负荷的步行器的研制

本研究的目的是设计和开发一种适合于在助行器辅助步态中测定上肢力量的仪器配置。为了实现这一目标，建立了传统铝管行走器的有限元模型，并在正交加载条件下对框架构件的串扰进行了充分描述。研究结果用于定位结构上的应变计传感器，以便确定单边手载荷的独立测量值。仪器配置以及校准数据说明了系统输出。在助行器辅助步态过程中上肢动力学的完整描述可能为康复治疗策略提供见解。对上肢需求的描述和对患者稳定性的评估可能会影响助行器的设计参数(身高、宽度、体重)和推荐的使用程序(脚的位置、手的位置、运动顺序和反馈负荷控制)。
