The aim of this study was to evaluate the relationship between knee pain and various indicators of the combined performance of the lower extremity (including gait parameters, functional performance such as timed up and go, and functional reach test) and to determine whether the classification of vertical ground reaction forces correlates with gait parameters and functional performance.
Simultaneous analysis of gait, time-distance parameters and vertical ground reaction force. Timed up and go, and functional reach test were examined in 130 elderly women. The vertical component of the ground reaction force was grouped into 2 categories: M-shaped and non-M-shaped.
No significant association was found between knee pain and timed up and go, functional reach test, or gait parameters in elderly female participants. There were significant differences between subjects with M- and non-M-shaped vertical ground reaction forces with regard to timed up and go, functional reach test and Japan Orthopaedic Association score. There were also significant differences between the 2 groups (M shaped and non-M-shaped) in gait parameters.
Evaluation of the vertical ground reaction force to determine its shape may be a useful and simple tool in the analysis of gait and functional performance.
本研究旨在评估膝关节疼痛与下肢综合表现的各项指标（包括步态参数、功能性表现如计时起立行走测试和功能性伸展测试）之间的关系，并确定垂直地面反作用力的分类是否与步态参数和功能性表现相关。
对步态、时间 - 距离参数和垂直地面反作用力进行同步分析。对130名老年女性进行计时起立行走测试和功能性伸展测试。地面反作用力的垂直分量分为两类：M形和非M形。
在老年女性参与者中，未发现膝关节疼痛与计时起立行走测试、功能性伸展测试或步态参数之间存在显著关联。M形和非M形垂直地面反作用力的受试者在计时起立行走测试、功能性伸展测试和日本骨科协会评分方面存在显著差异。两组（M形和非M形）在步态参数方面也存在显著差异。
评估垂直地面反作用力以确定其形状可能是分析步态和功能性表现的一种有用且简单的工具。
