踝足矫形器数学模型、应用处方及其早期应用对脑卒中患者偏瘫步态 影响的趋势分析(英文)

Mathematical model and applicable prescription of ankle-foot orthosis and its early application in analysis of hemiplegic gait of stroke patients

随着多体系统动力学理论和计算机技术的发展, 矫形器的计算机辅助设计和制造(CAD/CAM)技术已经日趋成熟,利用这项新技术可建立人体和矫形器的数学力学模型,通过模拟计算来确定矫形器处方、预测疗效和康复效果。踝足矫形器(AFO)早期应用对于脑卒中患者脑功能恢复、偏瘫步态恢复以及对于纠正异常步态起重要作用,在康复临床矫形器处方中,建立相应的数学模型,推测足踝功能变化和脑卒中后脑功能恢复的作用和机制,这对偏瘫步态的分析、矫形器的设计和患者步态的恢复等方面都会产生积极影响。

With the development of the Multi-Rigid-Body system dynamics theory and computer technology, computer aided design and manufacturing of orthosis have already matured, mathematical mechanical model of human body and orthosis can be established using this new technology, and simulation calculation can be used to determine the orthosis prescription, predict the efficacy and effectiveness of rehabilitation. Early application of ankle-foot orthosis plays an important role in restoration of brain function in stroke patients, resumption of hemiplegic gait and abnormal gait correction. In clinical orthosis prescription, establishment of corresponding mathematical model and speculation of ankle-foot function changes, as well as the effect and mechanism of resumption of brain function in post-stroke patients, have a positive impact on the analysis of hemiplegic gait, orthosis design and gait resumption.
