摘要

【目的】本研究旨在开发一种易于操作的膝关节-踝关节-足矫形器,该矫形器具有四种可调节的膝关节屈曲运动水平,并确定不同的屈曲运动范围对行走时膝关节屈曲角度的影响。【对象与方法】选取8例脑卒中患者为研究对象,构建膝踝足矫形器膝关节。行走时,测量以下四种膝关节设置的膝关节屈曲角度:自由屈曲、15°屈曲、30°屈曲和固定伸展。这些测量结果与之前一项研究中8名健康志愿者的测量结果进行了比较。[结果]步态分析显示,卒中患者中位时的膝关节屈曲角度在30°屈曲和自由屈曲时明显大于健康志愿者。[结论]使用为膝关节踝足矫形器研制的膝关节适当调节膝关节活动范围,可预防膝关节固定的膝关节踝足矫形器引起的废用性萎缩。

Comparison of gait between stroke patients and healthy volunteers using knee-ankle-foot orthoses with adjustable knee flexion.

[Purpose] This study aimed to develop an easy-to-operate knee joint for knee-ankle-foot orthoses with four adjustable levels of knee flexion movement and ascertain how different ranges of motion in flexion affect the knee flexion angle during walking. [Participants and Methods] Eight stroke patients participated, for whom knee joints of knee-ankle-foot orthoses were constructed. During walking, the knee flexion angle was measured for the following four knee joint settings: free flexion, 15° of flexion, 30° of flexion, and fixed extension. These measurements were compared to those of eight healthy volunteers from a previous study. [Results] Gait analysis revealed that the knee flexion angle during mid-stance was significantly greater in stroke patients than in healthy volunteers when set to 30° of flexion and in free flexion. [Conclusion] Appropriate adjustment of the range of knee mobility using a knee joint developed for knee-ankle-foot orthoses can prevent disuse atrophy caused by using knee-ankle-foot orthoses with a fixed knee joint.
