A traditional knee-ankle-foot orthosis (KAFO) for myopathic patients has been studied for the assessment of loads and fatigue resistance. Starting from this basis a thermoplastic matrix carbon fibre reinforced plastic composite (CFRP) KAFO has been developed in order to reduce the weight. A finite-element simulation programme for deformation analysis was used to compare the behaviour of conventional and CFRP orthosis. There were no breakages either of the prototype or of its parts. The CFRP orthosis allows a weight reduction of more than 40 per cent.
针对患有肌病的患者，对一种传统的膝-踝-足矫形器（KAFO）进行了负荷评估和抗疲劳性研究。在此基础上，开发了一种热塑性基体碳纤维增强塑料复合材料（CFRP）KAFO，以减轻重量。使用有限元模拟程序进行变形分析，比较传统矫形器和CFRP矫形器的性能。原型及其部件均未出现破损情况。CFRP矫形器的重量减轻了40%以上。
