A method for quantifying the stability of a patient using a walking frame is presented. Data collected from a walker-dependent patient recovering from surgical amputation of his right leg were used to demonstrate the derivation and interpretation of a proposed walker user risk index (WURI). WURI curves express risk to the walker user in terms of how much the upper extremities contribute to overall patient support. The WURI analysis of the walker stride presented here quantified the expected clinical impression that this patient was least reliant on the walker immediately after the advance of his prosthetic leg and most reliant when standing on his prosthesis and swinging his nonamputated leg. The analysis also revealed unexpectedly high upper body loads and specific phases in the gait cycle where the patient's balance was at risk.
本文提出了一种量化患者使用助行架时稳定性的方法。从一名因右腿手术截肢而依赖助行架的患者收集的数据，用于演示所提出的助行架使用者风险指数（WURI）的推导和解释。WURI曲线根据上肢对患者整体支撑的贡献程度来表达助行架使用者面临的风险。此处对助行架步幅的WURI分析量化了预期的临床印象，即该患者在假肢腿向前移动后立即对助行架的依赖最小，而在站立于假肢上并摆动未截肢的腿时对助行架的依赖最大。分析还揭示了意外高的上身负荷以及步态周期中患者平衡面临风险的特定阶段。
