“…Therefore, when the increase in TAF is considered the stiffness of TAF, the results of the study indicate that the subjects with a low stiffness of TAF walk with low ankle plantar flexion moment and have a large hip extension angle, whereas subjects with a high stiffness of TAF walk with high ankle plantar flexion moment and have a small hip extension angle. Previous research studies have reported that individuals with a high arch foot with high stiffness produce greater work of the ankle joint during landing and jogging, whereas individuals with a low arch foot with low stiffness produce greater work of the hip joint to overcome the reduced efficacy of a flexible foot34, 35 ) . The current study’s findings showed the same relationships as those reported in previous studies34, 35 ) that investigated the relationship between TAF stiffness and function of the hip joint and ankle joint during gait.…”

[Purpose] To investigate the relationship between the static measurement of the transverse arch of the forefoot, using a 3-dimensional (3D) foot scanner, and kinetics and kinematics of gait parameters in the sagittal plane. [Subjects and Methods] Twenty healthy subjects participated in this study. The transverse arch of the forefoot was measured under three conditions as follows: condition 1, sitting; condition 2, standing; and condition 3, foot forward and lower leg tilting anteriorly to the maximum position with heel contact. Gait parameters were recorded using a 3D motion analysis system and force plate. Correlation coefficients between TAF for each comparison of conditions and gait parameters were calculated using the Spearman correlation analysis. [Results] Rates of the transverse arch of the forefoot width and height between condition 2 and condition 3 were significantly correlated with the anterior and posterior component of ground reaction forces, the hip joint extension angle, and the ankle plantar flexion moment. [Conclusion] Our study’s findings indicated that increased stiffness of the transverse arch of the forefoot was related to the increase in ankle plantar moment, and decreased stiffness of the transverse arch of the forefoot was related to the increase in hip joint extension angle during gait.

“…It has been suggested that mal-alignment and abnormal mechanics of the foot may contribute to lower extremity injuries. These injures are associated with the dynamic foot function in load attenuation and force transmission through the lower extremity kinetic chain [3,4]. Excessive plantar pressure under any foot zone may increase the risk of soft tissue injuries, which may result in pain [5].…”

“…The COP displacement in the medial-lateral direction provided information on the MLA structure and dynamic functional behavior, while no effective parameters derived from the anterior-posterior direction of COP have been reported. Compared to running, walking is an activity with lower mechanical demand and smaller joint moments [4]. For young adults, there is a difference in temporal-spatial COP features in the sub-phases between walking and jogging.…”

Background: The medial longitudinal arch height has an effect on kinetic parameters during gait and might be related to the risk of injury. For the assessment of foot structures, the center of pressure (COP) trajectory is a more reliable and practical parameter than plantar pressure. This study aimed to clarify the COP trajectory and velocity characteristics in the medial-lateral and anterior-posterior direction of individuals with a high-arched foot during barefoot walking. Methods: Sixty-two healthy young adults were asked to walk over a Footscan pressure plate to record the COP parameters during the stance phase of walking. Results: Compared to normal arched feet, the COP during forefoot contact and foot flat phases of high-arched feet shifted anteriorly (19.9 mm and 15.1 mm, respectively), and the mean velocity of COP in anterior-posterior direction decreased by 0.26 m/s and increased by 0.044 m/s during these two phases respectively. Conclusions: The findings of this study suggest that the displacement and velocity of COP in anterior-posterior direction was different between high-arched and normal-arched subjects during barefoot walking, which can be used for the assessment of gait characteristics for high-arched individuals. The results of this study may provide insights into modifying clinical intervention for individuals with high-arched feet to enhance rehabilitation and prevent injuries and have implications for assessing the design of footwear and foot orthotics.

“…Finalmente, las diferencias encontradas en la componente 2 de los ángulos articulares no fueron detectadas por Buldt et al , quienes no encontraron diferencias significativas en el plano sagital. Sin embargo, Powell et al (Powell et al 2014) sí encontraron diferencias en la rigidez dinámica del tobillo de pies supinados frente a pies planos, si bien en carrera.…”

Als meus pares i al meu germà, sou i sereu el millor exemple AgradecimientosLlegados a este punto, es momento de dar las gracias a todas las personas que de una manera u otra han sido partícipes de que esta tesis llegue a buen puerto. Espero no olvidar a nadie.A mis directores, A Ximo por aceptar el reto de dirigir a un podólogo, por guiarme en todo momento, sobre todo cuando más perdido estaba, por enseñarme tanto durante este tiempo y por tu paciencia infinita. Sin ti no puedo imaginar esta tesis.A Javi, al que considero un referente en podología. Ha sido una suerte contar contigo en este proyecto.Agradecimiento muy especial a Alba, por tu trabajo en la implementación del modelo y tu ayuda y apoyos continuos durante todo el proceso de la tesis.A todos los sujetos que han participado en los experimentos. La realidad es que sin vuestros pies esta tesis no hubiera sido posible.Al grupo de investigación de Biomecánica y Ergonomía, por recibirme con los brazos abiertos desde el primer día.A mis compañeros de la Clínica Podológica de la Universitat de València. Trabajar con vosotros me hace crecer como podólogo.A mi familia. A mis padres, mi hermano y a Helena, por acompañarme y animarme en todo lo que hago. También sois parte de este trabajo. ResumenEsta tesis se presenta como un compendio de publicaciones encaminado a la caracterización de la dinámica de las articulaciones de la columna medial del pie (tobillo y articulaciones mediotarsiana y metatarsofalángica) con diferente índice postural.La revisión del estado del arte pone de manifiesto la escasez de trabajos que analicen las articulaciones del pie, más allá del tobillo, y que los existentes son poco sistemáticos debido a la complejidad del problema y con alta variabilidad en los resultados por su reducido tamaño muestral. Para reducir la complejidad, en otras articulaciones se ha propuesto el uso de la reducción dimensional o el estudio de la rigidez dinámica. Finalmente, es interesante estudiar la relación entre la postura estática del pie y la dinámica del pie durante la marcha, por la facilidad de uso en clínica de dicho indicador.La caracterización dinámica del pie con índice postural normal, altamente supinado y altamente pronado, se ha realizado atendiendo a diferentes métodos. En primer lugar se utiliza la representación tradicional de evolución temporal de rotaciones y momentos articulares en los tres planos de movimiento, arrojando intervalos de confianza más estrechos que los reportados previamente en la literatura. Asimismo se dan valores de los parámetros descriptivos de estas curvas, los cuales han permitido identificar tres patrones de marcha en pies con índice postural normal, y se proporcionan ecuaciones para su clasificación. En particular, se incide en la descripción de la articulación mediotarsiana, con curvas bastante diferentes en cada plano de movimiento, momentos dorsiflexores considerablemente mayores en el plano sagital, y rotaciones muy estables en los planos frontal y transverso durante el periodo de apoyo medio.La caracterización ...
