Following stroke an equinus deformity of the foot may develop, which may affect the gait pattern of patients differently. Sub-categorization of gait patterns in these patients would be helpful in developing and delivering more targeted treatment. A hierarchical cluster analysis was used to classify the gait patterns of 23 chronic stroke patients with equinus deformity of the foot based on temporal distance parameters and joint kinematic and kinetic measures in the sagittal and coronal planes. Cluster analysis showed that gait patterns were not singularly homogenous and identified three subgroups that contained within group homogenous levels of function. Further analysis identified significant differences between the subgroups in some of the temporal distance and kinematic and kinetic measures examined. The results from this study can be used to categorise patients, facilitating appropriate development of targeted treatment.
中风后可能会出现足马蹄内翻畸形，这可能会对患者的步态模式产生不同影响。对这些患者的步态模式进行亚分类将有助于制定和提供更具针对性的治疗。基于矢状面和冠状面的时间距离参数以及关节运动学和动力学测量，采用层次聚类分析对23例患有足马蹄内翻畸形的慢性中风患者的步态模式进行分类。聚类分析表明，步态模式并非单一同质，并识别出三个亚组，每个亚组内功能水平同质。进一步分析发现，在一些所检查的时间距离以及运动学和动力学测量方面，亚组之间存在显著差异。本研究结果可用于对患者进行分类，有助于针对性治疗的合理制定。
