材料和方法3个人先后使用装有测压元件的器械假体以及普通和拟人的脚行走、上、下楼梯和坡道。结果从319个步态周期(GCs)中提取的绝对最大载荷分别为48%BW、17%BW和112%BW，以及2%BWM、13%BWM和1%BWM，分别用于假体前后、内侧和长轴上和周围的力矩。讨论新的证据表明，依赖于三轴直接测量，可以获得能够区分经胫骨锚定假体的特定和全面的载荷特征记录除行走外的一系列日常活动，并考虑至少九种负荷极限。结论假肢护理提供者可以利用这一特征为全球越来越多的胫骨截肢患者安装骨整合植入物进行循证匹配。
Materials and MethodsThree individuals walked and ascended and descended stairs and ramps with instrumented prostheses fitted with a load cell as well as usual and anthropomorphic feet successively. The characterization of the loading profile involved the comparison of 100 variables including spatiotemporal characteristics, loading boundaries, local extremum, and impulse.ResultsThe absolute maximum load extracted from 319 gait cycles (GCs) with both prostheses across all activities was 48% BW, 17% BW, and 112% BW for the forces as well as 2% BWm, 13% BWm, and 1% BWm for the moments on and around the anteroposterior, mediolateral, and long axes of the implant, respectively.DiscussionNew evidence presented here indicated that a specific and comprehensive loading characterization capable of differentiating transtibial bone-anchored prostheses was achievable when relying on triaxial direct measurements, recording a range of daily activities in addition to walking, and considering at least nine loading extremum.ConclusionsProsthetic care providers could use this characterization for evidence-based fitting of components to the growing population of individuals with transtibial amputation fitted with osseointegrated implants worldwide.
