Gait Posture. 2000 Oct;12(2):162-8. doi: 10.1016/s0966-6362(00)00069-2.
This study scientifically measures the dynamic gait characteristics and energy consumption of 16 male below-knee amputees, eight vascular and eight traumatic, while wearing solid ankle cushion heel (SACH), single axis and multiple axis prosthetic feet via six-camera motion analysis, metabolic measurement cart and heavy-duty treadmill. Subjective results are additionally determined via questionnaire after testing. Motion analysis showed statistically significant differences at P<0.05 between the SACH, single axis and multiple axis foot in the velocity, cadence, stride length and single limb stance. Significant differences were found in energy consumption between the traumatic and vascular groups, and significant changes in walking under different speeds and different inclines. Results provide quantitative and qualitative information about the dynamic performance of the various feet, which can be helpful in prescribing the optimal prosthetic foot for individual amputees.
本研究通过六台摄像机运动分析、代谢测量推车和重型跑步机，科学测量了16名男性膝下截肢者（8名血管性截肢者和8名外伤性截肢者）在穿戴实心踝垫足跟（SACH）假脚、单轴假脚和多轴假脚时的动态步态特征和能量消耗。测试后还通过问卷调查确定主观结果。运动分析显示，SACH假脚、单轴假脚和多轴假脚在速度、步频、步幅和单腿支撑方面存在统计学上的显著差异（P<0.05）。外伤性截肢组和血管性截肢组在能量消耗方面存在显著差异，且在不同速度和不同坡度下行走时也有显著变化。研究结果提供了关于各种假脚动态性能的定量和定性信息，有助于为个体截肢者开具最佳的假脚处方。
