This proof of concept study presents a method to collect and analyse kinetic data from one participant with a transfemoral amputation fitted with a percutaneous osseointegrated implant walking on a level and sloped treadmill. We describe the construction of and results from a bespoke wireless six axis load cell built into one participant's prosthetic assembly. The load cell does not clinically compromise the participant in any way and is an initial milestone in the development of a light-weight wireless load cell for use with percutaneous osseointegrated implants. In this case, it is the first time that kinetic data from a participant fitted with an Intraosseous Transcutaneous Amputation Prosthesis has been published. We propose that the data can be used to model the load transfer to the host bone, with several clinically significant applications. The raw dynamic data are made available and quasi-static load cases for each functional phase of gait are presented. Peak forces obtained in the medio-lateral (X), cranio-caudal (Y) and antero-posterior (Z) axes over level ground respectively were -243.8 N (0.24 BW), 1321.5 N (1.31 BW) and -421.8 N (0.42 BW); uphill were -141.0 N (0.14 BW), 1604.2 N (1.59 BW), -498.1 (0.49 BW); downhill were -206.0 N (0.20 BW), 1103.9 N (1.09 BW), -547.2 N (0.54 BW). The kinetics broadly followed non-amputated gait patterns with some gait strategies consistent in participants with other implant designs or prosthetic socket connections, for example offloading the artificial limb downhill.

这项概念验证研究提出了一种收集和分析一名配备经皮骨整合植入物的股骨截肢参与者在水平和倾斜跑步机上行走的动力学数据的方法。我们描述了内置于一名参与者的假肢组件中的定制无线六轴称重传感器的构造和结果。该称重传感器在临床上不会以任何方式损害参与者，并且是开发用于经皮骨整合植入物的轻型无线称重传感器的最初里程碑。在这种情况下，这是首次发布来自安装骨内经皮截肢假体的参与者的动力学数据。我们建议这些数据可用于模拟到宿主骨的负载转移，并具有一些具有临床意义的应用。提供原始动态数据，并呈现步态每个功能阶段的准静态载荷情况。在水平地面上的中侧 (X)、头尾 (Y) 和前后 (Z) 轴上获得的峰值力分别为 -243.8 N (0.24 BW)、1321.5 N (1.31 BW) 和 -421.8 N ( 0.42 带宽）；上坡分别为 -141.0 N (0.14 BW)、1604.2 N (1.59 BW)、-498.1 (0.49 BW)；下坡分别为-206.0 N (0.20 BW)、1103.9 N (1.09 BW)、-547.2 N (0.54 BW)。动力学大致遵循非截肢步态模式，其中一些步态策略与其他植入物设计或假肢接受腔连接的参与者一致，例如下坡时卸载假肢。
