Accurate fitting of a lower-limb prosthetic socket is the most important factor affecting amputee satisfaction and rehabilitation. The technology is now available to allow real-time monitoring of in-service pressure distribution of prosthetic limbs. This paper proposes a remote interfacial pressure monitoring system necessary for the assessment of fit. The suitability of a wireless ZigBee network due to its relevant technical specification is investigated. The system enables remote monitoring of a prosthetic socket and its fit under different operating conditions thereby improving design, efficiency and effectiveness. The data can be used by prosthetists and may also be recorded for future training or for patient progress monitoring. This can minimize the number of iterations by getting it right first time, thereby minimizing the number of replacement prostheses.
下肢假肢接受腔的精确适配是影响截肢者满意度和康复效果的最重要因素。目前已有技术可实现对假肢在役压力分布的实时监测。本文提出了一种用于评估适配情况的远程界面压力监测系统。研究了因相关技术规格而适用于此的无线 ZigBee 网络。该系统能够在不同操作条件下对假肢接受腔及其适配情况进行远程监测，从而改善设计、提高效率和有效性。这些数据可供假肢师使用，也可记录下来用于未来培训或患者进展监测。这样可以通过一次就做好而减少迭代次数，从而减少假肢更换数量。
