The aim of this study was to identify the cascade of effects leading from alterations in force generation around the ankle joint to increased plantar pressures under the forefoot. Gait analysis including plantar pressure measurement was performed at an individually preferred and a standardized, imposed gait velocity in diabetic subjects with polyneuropathy (n=94), without polyneuropathy (n=39) and healthy elderly (n=19). The plantar flexion moment at 40% of the stance phase was negatively correlated with the displacement rate of center of pressure (r=-.749, p<.001 at the imposed, and r=-.693, p<.001 at the preferred gait velocity). Displacement rate of center of pressure was strongly correlated with forefoot loading (r=-.837, p<.001 at the imposed, and r=-.731, p<.001 at the preferred gait velocity). People with a relatively high plantar flexion moment at 40% of the stance phase, have a faster forward transfer of center of pressure and consequently higher loading of the forefoot. This indicates that interventions aimed at increasing the control of the roll-off of the foot may contribute to a better plantar pressure distribution.
本研究旨在确定从踝关节周围力生成的改变到前脚下足底压力增加的级联效应。对伴有多发性神经病的糖尿病患者（n=94）、无多发性神经病的糖尿病患者（n=39）和健康老年人（n=19）进行了个体化喜好和标准化强制步态速度的步态分析，包括足底压力测量。在站立相的 40%时，跖屈力矩与压力中心位移率呈负相关（在强制步态速度时 r=-.749，p<.001，在喜好步态速度时 r=-.693，p<.001）。压力中心位移率与前足负荷呈强相关（在强制步态速度时 r=-.837，p<.001，在喜好步态速度时 r=-.731，p<.001）。在站立相的 40%时跖屈力矩较高的人，压力中心向前转移较快，前足负荷较高。这表明，旨在增加对足部滚动控制的干预措施可能有助于改善足底压力分布。
