This study presents the walking abilities of participants fitted with transfemoral bone-anchored prostheses using a total of 14 gait parameters.
Two-centre retrospective cross-sectional comparative study.
Research facilities equipped with tridimensional motion capture systems.
Two control arms included eight able-bodied participants arm (54 ± 9 years, 1.75 ± 0.07 m, 76 ± 7 kg) and nine participants fitted with transfemoral socket-suspended prostheses arm (59 ± 9 years, 1.73 ± 0.07 m, 80 ± 16 kg). The intervention arm included nine participants fitted with transfemoral bone-anchored prostheses arm (51 ± 13 years, 1.78 ± 0.09 m, 87.3 ± 16.1 kg).
Fitting of transfemoral bone-anchored prostheses.
Comparisons were performed for two spatio-temporal, three spatial and nine temporal gait parameters.
The cadence and speed of walking were 107 ± 6 steps/min and 1.23 ± 0.19 m/s for the able-bodied participants arm, 88 ± 7 steps/min and 0.87 ± 0.17 m/s for the socket-suspended prosthesis arm, and 96 ± 6 steps/min and 1.03 ± 0.17 m/s for bone-anchored prosthesis arm, respectively. Able-bodied participants and bone-anchored prosthesis arms were comparable in age, height, and body mass index as well as cadence and speed of walking, but the able-bodied participant arm showed a swing phase 31% shorter. Bone-anchored and socket-suspended prostheses arms were comparable for age, height, mass, and body mass index as well as cadence and speed of walking, but the bone-anchored prosthesis arm showed a step width and duration of double support in seconds 65% and 41% shorter, respectively.
Bone-anchored and socket-suspended prostheses restored equally well the gait parameters at a self-selected speed. This benchmark data provides new insights into the walking ability of individuals using transfemoral bionics bone-anchored prostheses.
本研究使用 14 项步态参数呈现了接受股骨骨锚定假体的参与者的行走能力。
双中心回顾性交叉对比研究。
配备三维运动捕捉系统的研究设施。
两个对照组分别纳入 8 名健全参与者（54±9 岁，1.75±0.07m，76±7kg）和 9 名接受股骨套接式悬吊假体的参与者（59±9 岁，1.73±0.07m，80±16kg）。干预组纳入 9 名接受股骨骨锚定假体的参与者（51±13 岁，1.78±0.09m，87.3±16.1kg）。
股骨骨锚定假体的安装。
对 2 项时空、3 项空间和 9 项时间步态参数进行了比较。
健全参与者手臂的步频和步行速度分别为 107±6 步/分钟和 1.23±0.19m/s，套接式悬吊假体手臂为 88±7 步/分钟和 0.87±0.17m/s，骨锚定假体手臂为 96±6 步/分钟和 1.03±0.17m/s。健全参与者和骨锚定假体手臂在年龄、身高和体重指数以及步频和步行速度方面具有可比性，但健全参与者手臂的摆动相短 31%。骨锚定和套接式悬吊假体手臂在年龄、身高、质量和体重指数以及步频和步行速度方面具有可比性，但骨锚定假体手臂的步宽和双支撑持续时间分别短 65%和 41%。
骨锚定和套接式悬吊假体在自我选择的速度下同样很好地恢复了步态参数。这些基准数据为使用股骨仿生骨锚定假体的个体的行走能力提供了新的见解。
