Abstract

Background

Plantar pressure distribution during walking in patients with painful Ledderhose disease is unknown.

Research question

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.

Methods

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.

Results

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.

Significance

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.

疼痛性Ledderhose病对步行过程中足底动态压力分布的影响：一项病例对照研究。

背景：患有疼痛性Ledderhose病的患者行走时足底压力的分布尚不清楚。研究问题：与没有足部疾病的患者相比，患有疼痛性莱德霍斯病的患者在行走过程中足底压力分布是否发生了改变？假设足底压力从疼痛的结节转移开。方法：收集41例疼痛性Ledderhose病患者（例，平均年龄：54.2±10.4岁）的足压图数据，并与41例无足部疾病的患者（对照组，平均年龄21.7±2.0岁）的足压图数据进行比较。计算了脚底下八个区域（脚跟、中足内侧、中足外侧、前脚内侧、前脚中央、前脚外侧、拇趾和其他脚趾）的峰值压力（PP）、最大平均压力（MMP）和力时积分（FTI）。病例和对照组之间的差异通过线性（混合模型）回归进行计算和分析。结果：与对照组相比，PP、MMP和FTI的比例差异显示，病例的值增加，尤其是在足跟、拇趾和其他脚趾区域，而在足中部内侧和外侧区域的值降低。在天真的回归分析中，作为一名患者是几个地区PP、MMP和FTI值升高和降低的预测因素。当使用线性混合模型回归分析考虑数据中的依赖性时，患者的FTI值的增加和减少在脚跟、足中内侧、拇趾和其他脚趾区域最为普遍。意义：在患有疼痛性Ledderhose病的患者中，在行走过程中，发现压力向足的近端和远端转移，同时减轻足中部的压力。

期刊介绍： The Foot is an international peer-reviewed journal covering all aspects of scientific approaches and medical and surgical treatment of the foot. The Foot aims to provide a multidisciplinary platform for all specialties involved in treating disorders of the foot. At present it is the only journal which provides this inter-disciplinary opportunity. Primary research papers cover a wide range of disorders of the foot and their treatment, including diabetes, vascular disease, neurological, dermatological and infectious conditions, sports injuries, biomechanics, bioengineering, orthoses and prostheses.
