Clinicians are currently in demand of tools enabling individual assessment during their daily practice of load-relief of walking aids. The first aim of this article is to describe a portable kinetic system that could be used to measure directly the true load applied on the residuum during assisted walking. The second aim is to present the information that can be derived from the raw loading data. The third aim is to provide an example for a participant. One active transfemoral amputee fitted with an osseointegrated fixation was asked to walk in straight level line with no aid, one stick, one and two elbow crutches on a 20 m walkway. The load-relief was measured using a six-channel transducer and recorded using a data logger. The overall loading was decreased by 2% using one stick, 5% using one crutch and by 10% using two crutches. This study presents a method that can be used by clinicians facing the challenge of prescribing and assessing walking aids to restore the locomotion of lower limb amputees in the framework of an evidence-based practice.
临床医生目前需要在日常实践中对助行器减负进行个体评估的工具。本文的首要目的是描述一种便携式动力学系统，该系统可用于在辅助行走过程中直接测量施加在残肢上的实际负荷。第二个目的是展示可从原始负荷数据中得出的信息。第三个目的是为一名参与者提供一个示例。一名安装了骨整合固定装置的主动型经股骨截肢者被要求在一条20米长的人行道上不借助任何辅助、使用一根手杖、一根和两根肘拐直线行走。使用六通道传感器测量减负情况，并使用数据记录器进行记录。使用一根手杖时总负荷降低了2%，使用一根肘拐时降低了5%，使用两根肘拐时降低了10%。本研究提出了一种方法，可供面临为下肢截肢者开出处方和评估助行器以恢复其运动能力这一挑战的临床医生在循证实践框架内使用。
