After transfemoral amputation a prosthesis is required to restore autonomous standing and bipedal locomotion. Attachment of the prosthesis can be achieved either classically via socket suspension with a shaft in the stump or directly via implantation of an intramedullary transcutaneous femoral prosthesis (osseointegrated prosthesis).
A fully instrumented gait analysis should enable objectification of the anticipated advantages of the EEP with respect to the gait pattern and individual mobility.
In two patients with a unilateral transfemoral amputation a comprehensive gait analysis was carried out prior to and 6 months (patient 1) or 11 and 20 months (patient 2) after switching from a socket prosthesis to an EEP. This was carried out in the Gait Realtime Analysis Interactive Lab (GRAIL), a fully instrumented gait laboratory with virtual reality and enables assessment close to the conditions of daily life.
In both cases the gait analysis confirmed the advantages associated with an EEP for the transmission of force to the prosthesis and the accompanying improvement in gait symmetry.
经股截肢后，需要安装假肢以恢复自主站立和双足行走。假肢的附着可以通过传统方式，即使用残肢内带有杆的接受腔悬吊来实现，也可以直接通过植入髓内经皮股骨假肢（骨整合假肢）来实现。
全面的步态分析应能客观地体现骨整合假肢在步态模式和个体移动性方面预期的优势。
对两名单侧经股截肢患者，在从接受腔假肢转换为骨整合假肢之前以及转换后6个月（患者1）或11个月和20个月（患者2）进行了全面的步态分析。这是在步态实时分析互动实验室（GRAIL）中进行的，该实验室是一个配备齐全的步态实验室，具有虚拟现实功能，能够在接近日常生活的条件下进行评估。
在这两个案例中，步态分析均证实了骨整合假肢在向假肢传递力量以及随之而来的步态对称性改善方面的优势。
