To evaluate the gait patterns of lower limb amputee patients walking with and without shoes and to identify differences in barefoot gait patterns when using different prosthetic feet.
Optoelectronic three-dimensional motion analysis of gait was performed on six transtibial amputees using a solid ankle cushion heel foot and a single-axis foot, both with and without shoes.
Gait abnormalities were observed during barefoot walking when the solid ankle cushion heel foot was used. These included knee joint hyperextension of 9.9 +/- 2.0 degrees and the loss of ankle plantar flexion in the early stance phase. When the single-axis foot was used, knee flexion thrust declined from 9.9 +/- 3.7 degrees to 7.2 +/- 3.8 degrees and ankle plantar flexion decreased from 9.9 +/- 2.8 degrees to 7.0 +/- 2.1 degrees during the early stance phase.
In transtibial amputees, significant gait abnormalities were observed during barefoot walking using the solid ankle cushion heel foot. These gait patterns improved, however, with use of a single-axis prosthetic foot, which permits a further plantar flexion after the initial contact.
评估下肢截肢患者穿鞋与不穿鞋行走时的步态模式，并确定使用不同假肢脚时裸足步态模式的差异。
对6名经胫截肢者使用实心踝垫足跟脚和单轴脚，分别在穿鞋和不穿鞋的情况下进行步态的光电三维运动分析。
使用实心踝垫足跟脚进行裸足行走时观察到步态异常。这些异常包括膝关节过伸9.9±2.0度以及在站立初期踝关节跖屈丧失。使用单轴脚时，站立初期膝关节屈曲推力从9.9±3.7度降至7.2±3.8度，踝关节跖屈从9.9±2.8度降至7.0±2.1度。
在经胫截肢者中，使用实心踝垫足跟脚进行裸足行走时观察到明显的步态异常。然而，使用单轴假肢脚时这些步态模式有所改善，单轴假肢脚允许在初始接触后进一步跖屈。
