Abstract：
Bilateral amputees are disadvantaged as they lack healthy leg support. We present the rare case of a bilateral transtibial amputee (BTA), in which we compared the first South Korean-made microprocessor-controlled prosthesis (MPA) to a conventional prosthetic ankle (CPA) with gait analysis and a patient questionnaire for long-term outcomes. A 70-year-old man presented with bilateral transtibial amputations from injury. Assessments were performed after wearing an MPA for 1 month and 1 year with three-dimensional gait analysis. Satisfaction, mobility, and pain were evaluated using the Korean version of the Prostheses Evaluation Questionnaire (K-PEQ). The spatiotemporal parameters of both sides showed increased stability from the CPA to 1 month (mMPA) and 1 year (yMPA). We observed an increased single support time, decreased step width, and almost normal stance-swing time ratio. In kinematic parameters, the ankle range of motion (ROM) was bilaterally increased at mMPA and yMPA. Unfortunately, the MPA gait showed insufficient ankle plantarflexion during the terminal stance that failed to generate push-up power. As the MPA adaptation time increased, the symmetry ratio improved to a balanced value. The questionnaire-based investigations of satisfaction, mobility, and pain revealed excellent results. The MPA proved helpful for ankle mobility in the BTA, and the questionnaire showed good satisfaction and mobility in varied terrain.
摘要：
双边截肢者处于不利地位，因为他们缺乏健康的腿部支持。我们介绍了罕见的双侧胫骨截肢者（BTA），其中我们将第一个韩国制造的微处理器控制的假肢(MPA)与传统的假肢踝关节(CPA)进行了比较,并进行了步态分析和长期结局的患者问卷调查.一名70岁的男子因受伤而出现双侧胫骨截肢。在佩戴MPA1个月和1年后，通过三维步态分析进行评估。满意,移动性,使用韩文版的假体评估问卷（K-PEQ）评估疼痛。两侧的时空参数显示从CPA到1个月（mMPA）和1年（yMPA）的稳定性增加。我们观察到单个支持时间增加，宽度减小，和几乎正常的姿势摆动时间比。在运动学参数中，在mMPA和yMPA时，踝关节活动范围（ROM）双侧增加。不幸的是,MPA步态显示,在末端站立时踝关节前屈不足,无法产生俯卧撑力.随着MPA适应时间的增加，对称比提高到一个平衡值。满意度问卷调查，移动性,疼痛显示出优异的效果。MPA被证明对BTA的脚踝活动有帮助，问卷在不同的地形下表现出良好的满意度和机动性。
