下肢截肢患者的步态模式分类有助于制定个性化的假肢处方和定制的步态康复。然而，在这个人群中的步态模式的系统分类几乎没有探索。本研究旨在确定单侧经股动脉截肢（UTFA）患者的步态模式是否可以使用步行速度范围内的时空参数聚类为同质亚组。我们研究了时空步态参数，包括步长和节奏，在25个人与UTFA（功能水平K3或K4，所有非血管截肢），而他们走在一个分裂带仪表跑步机在八个速度。基于步长和步频之间的关系，采用层次聚类分析（HCA）来识别具有同质步态模式的聚类。此外，聚类形成后，进行事后分析，比较集群之间的时空参数和人口数据。HCA确定了三个同质的步态模式集群，这表明UTFA的个人有几个步态模式。此外，我们发现参与者的身高，性别比例和他们的假肢膝关节组件之间的集群显着差异。因此，步态康复应根据人体尺寸和假肢处方进行个体化。
Gait pattern classification in individuals with lower-limb amputation could help in developing personalized prosthetic prescriptions and tailored gait rehabilitation. However, systematic classifications of gait patterns in this population have been scarcely explored. This study aimed to determine whether the gait patterns in individuals with unilateral transfemoral amputation (UTFA) can be clustered into homogeneous subgroups using spatiotemporal parameters across a range of walking speeds. We examined spatiotemporal gait parameters, including step length and cadence, in 25 individuals with UTFA (functional level K3 or K4, all non-vascular amputations) while they walked on a split-belt instrumented treadmill at eight speeds. Hierarchical cluster analysis (HCA) was used to identify clusters with homogeneous gait patterns based on the relationships between step length and cadence. Furthermore, after cluster formation, post-hoc analyses were performed to compare the spatiotemporal parameters and demographic data among the clusters. HCA identified three homogeneous gait pattern clusters, suggesting that individuals with UTFA have several gait patterns. Further, we found significant differences in the participants’ body height, sex ratio, and their prosthetic knee component among the clusters. Therefore, gait rehabilitation should be individualized based on body size and prosthetic prescription.
