Plantar pressure distribution during walking in patients with painful Ledderhose disease is unknown.
Do patients with painful Ledderhose disease have an altered plantar pressure distribution during walking compared to individuals without foot pathologies? It was hypothesized that plantar pressure is shifted away from the painful nodules.
Pedobarography data of 41 patients with painful Ledderhose disease (cases, mean age: 54.2 ± 10.4 years) was collected and compared to pedobarography data from 41 individuals without foot pathologies (controls, mean age: 21.7 ± 2.0 years). Peak Pressure (PP), Maximum Mean Pressure (MMP) and Force-Time Integral (FTI) were calculated for eight regions (heel, medial midfoot, lateral midfoot, medial forefoot, central forefoot, lateral forefoot, hallux and other toes) under the soles of the feet. Differences between cases and controls were calculated and analysed by means of linear (mixed models) regression.
Proportional differences in PP, MMP and FTI showed increased values for the cases compared to the controls, especially in the heel, hallux and other toes regions, and decreased values in the medial- and lateral midfoot regions. In naïve regression analysis, being a patient was a predictor for increased- and decreased values for PP, MMP and FTI for several regions. When dependencies in the data were taken into account with linear mixed-model regression analysis, the increased- and decreased values for the patients were most prevalent for FTI at the heel, medial midfoot, hallux and other toes regions.
In patients with painful Ledderhose disease, during walking, a shift of pressure was found towards the proximal and distal foot regions, while offloading the midfoot regions.
足底压力分布在患有疼痛性莱德霍斯病的患者行走时是未知的。
与无足部病理的个体相比，患有疼痛性莱德霍斯病的患者在行走时足底压力分布是否发生改变？据推测，足底压力从疼痛结节处转移。
收集 41 例疼痛性莱德霍斯病患者（病例组，平均年龄：54.2±10.4 岁）和 41 例无足部病理患者（对照组，平均年龄：21.7±2.0 岁）的足底压力图数据。计算足底八个区域（足跟、内侧中足、外侧中足、内侧前足、中央前足、外侧前足、大脚趾和其他脚趾）的峰值压力（PP）、最大平均压力（MMP）和力-时间积分（FTI）。通过线性（混合模型）回归计算病例组和对照组之间的差异，并进行分析。
病例组与对照组相比，PP、MMP 和 FTI 的比例差异显示出较高的值，特别是在足跟、大脚趾和其他脚趾区域，而在中足和外侧中足区域的值较低。在初始回归分析中，作为患者是 PP、MMP 和 FTI 几个区域值增加和减少的预测因素。当线性混合模型回归分析考虑到数据中的依赖性时，患者的增加和减少值最常见于足跟、内侧中足、大脚趾和其他脚趾区域的 FTI。
在患有疼痛性莱德霍斯病的患者中，在行走时，发现压力向足部近端和远端区域转移，而中足区域则减轻了压力。
