经胫骨截肢（TTA）的患者在行走过程中福尔斯的发生率很高。环境因素，如不平坦的地面，往往在这些福尔斯中发挥作用。本研究的目的是量化的适应TTA时，走在不稳定的松散的岩石表面。在这项研究中，13名年轻的TTA以四种受控速度走过岩石表面和水平地面。受试者成功地通过岩石表面采取保守的步态特征的短，宽的步骤。他们使用假肢的步伐也更短，当踏上完整的肢体时，脚的位置表现出更大的变化性。肢体之间的差异，步长和宽度的变化增加，在更快的步行速度。TTA增加髋关节和膝关节屈曲在初始的立场，这有助于降低全身质心。TTA还增加了摆动过程中的髋关节和膝关节屈曲，使他们能够显着增加他们的脚趾间隙在岩石表面相比，平地。增加同侧髋关节屈曲有助于假体侧的脚趾间隙。结果表明，TTA能够适应他们的步态，以克服岩石表面带来的挑战。这些适应是不对称的，并开始近端。
Individuals with transtibial amputation (TTA) have a high incidence of falls during walking. Environmental factors, such as uneven ground, often play a contributing role in these falls. The purpose of this study was to quantify the adaptations TTA made when walking on a destabilizing loose rock surface. In this study, 13 young TTA walked over a rock surface and level ground level ground at four controlled speeds. Subjects successfully traversed the rock surface by adopting a conservative gait characterized by shorter and wider steps. They also took shorter steps with their prosthetic limbs and exhibited greater variability in foot placement when stepping onto their intact limb. Between-limb differences in step length and width variability increased at faster walking speeds. TTA increased hip and knee flexion during initial stance, which contributed lowering the whole-body center of mass. TTA also increased hip and knee flexion during swing, enabling them to significantly increase their toe clearance on the rock surface compared to level ground. Toe clearance on the prosthetic side was aided by increased ipsilateral hip flexion. The results suggest that TTA were able to adapt their gait to overcome the challenge imposed by the rock surface. These adaptations were asymmetric and initiated proximally.
