“…The plantar pressure distribution also showed a good agreement between the FE modelling and biomechanical tests. These are commonly used approaches to check the validity and accuracy of FEMs [14,29,30]. These will provide confidence in the prediction of the stresses in the metatarsals in forefoot and rearfoot strike, which is the main focus of the work.…”

“…In the experimental work, we used reflective markers to record the displacement of the ankle and deformation of the foot. The averaged displacement history at top surface of the model (including tibia, fibula and soft tissue) was used to control the foot landing in the model, this is more realistic than moving the plate [27,28,30]. The initial touchdown angle in forefoot and rearfoot strike between the foot plantar and the ground was defined as 5° by gait measurement with reflective markers.…”

Due to the limitations of experimental approaches, comparison of the internal deformation and stresses of the human man foot between forefoot and rearfoot landing is not fully established. The objective of this work is to develop an effective FE modelling approach to comparatively study the stresses and energy in the foot during forefoot strike (FS) and rearfoot strike (RS). The stress level and rate of stress increase in the Metatarsals are established and the injury risk between these two landing styles is evaluated and discussed. A detailed subject specific FE foot model is developed and validated. A hexahedral dominated meshing scheme was applied on the surface of the foot bones and skin. An explicit solver (Abaqus/Explicit) was used to stimulate the transient landing process. The deformation and internal energy of the foot and stresses in the metatarsals are comparatively investigated. The results for forefoot strike tests showed an overall higher average stress level in the metatarsals during the entire landing cycle than that for rearfoot strike. The increase rate of the metatarsal stress from the 0.5 body weight (BW) to 2 BW load point is 30.76% for forefoot strike and 21.39% for rearfoot strike. The maximum rate of stress increase among the five metatarsals is observed on the 1st metatarsal in both landing modes. The results indicate that high stress level during forefoot landing phase may increase potential of metatarsal injuries.

ResumenLa reconstrucción del pie es un tema amplio y complejo abordado frecuentemente desde el ámbito clínico, pero pocas veces desde el punto de vista de la Bioingeniería.Este artículo muestra un método de simulación computacional mediante elementos finitos partiendo de imágenes de resonancia magnética de un pie reconstruido quirúrgicamente. Tras la creación de los modelos en 3D del pie en diferentes momentos evolutivos y con la utilización de los datos aportados por la podobarografía estática, se realizan los cálculos que muestran las diferencias de incremento en las deformaciones ocurridas en cada uno de los tejidos implicados en la reconstrucción quirúrgica en dos momentos evolutivos diferentes, teniendo en cuenta las características de carga del paciente en cada uno de ellos. Esto permite hacernos una idea teórica del comportamiento de los tejidos participantes en una reconstrucción vistos como un material deformable.Como resultado vemos que el volumen global de los tejidos disminuye y se adapta a los contornos, que el músculo es el tejido que más aumenta su valor relativo de deformación, y que la grasa es el tejido que mayor deformación sufre en cuanto a valores absolutos se refiere. El hueso, por sus propiedades mecánicas, apenas sufre deformaciones. La distribución de las deformaciones es compatible con la clínica y va modificándose a lo largo del tiempo.La utilización de la Bioingeniería aplicada a la Cirugía Plás-tica aporta gran cantidad de información que puede usarse para la comparación tanto en el mismo paciente, como entre pacientes con diferentes características o para realizar previsiones.Palabras clave Microcirugía, Reconstrucción plantar, Apoyo plantar, Podobarografía, Ingeniería biomédica.

After the creation of 3D models of the foot in different evolutionary stages and the use of data provided by static podobarography, the calculations show differences in the increase of deformation occurred in each of the tissues involved in reconstruction. It is made into two different evolutionary surgical times, taking into account the load characteristics of the patient in each. This allows us a theoretical idea of the behavior of tissues participating in the reconstruction as deformable material.In results section, it´s shown that the global volume of tissue decreases and adapts to the contours, the muscle is the tissue that further increases its relative value of deformation and fat is the tissue that greater deformation suffers in terms of absolute values refer. The bone mechanical properties hardly undergoes deformations. Deformations distribution is compatible with the clinical and evolves with time over. The contact surface and the maximum pressures are simila...

“…Such early models were used for material sensitivity studies [11], [33] and for investigating the effects of insole geometry on plantar pressure distribution [9]. Advances in FEA and IT led to the development of improved models [10], [47] followed by more advanced simulation cases [1], [11], [21], [25], [56], [7]. Some assumptions are often made, e.g.…”

Footwear is one of the most widely and intensively used human centric products. Evaluating and optimizing footwear performance is of outmost importance for human comfort. This paper presents a definition of foot plantar mechanical comfort along with a detailed approach for evaluating it through finite element analysis. An extensive review of biomechanical and shoe mechanical aspects related to human comfort is presented providing ample justification for the selection of the comfort characteristics which are addressed in this paper. A foot biomodel has been developed which is combined with solid shoe structures in order to evaluate plantar pressures distribution and shock absorption. In addition, bending and torsional behavior of shoe structures is also taken into account and, therefore, appropriate finite element models have been developed and tested. All experiments are analytically presented and discussed, while the related results illustrate the potential of the proposed approach to support footwear design optimization under an integrated biomechanics-enabled framework.
