[en] INTRODUCTION Diabetes mellitus is one of the biggest epidemics of the 21st century. One of the main problems that can suffer from this type of patients is called diabetic foot, those people who present it together with loss of sensation and motor neuropathy, are more vulnerable to presenting areas of hyperpressure in the feet, which is the main triggering factor of diabetic foot ulcers. Currently, podiatrists have a wide variety of techniques to deal with plantar hyperpressions, including plantar supports, as well as a multitude of materials for making them, whose purpose, among others, is to make a homogeneous distribution of the pressures that the foot supports during the march, thus alleviating the painful symptomatology. OBJECTIVES The objective of this study is to know the viscoelastic and mechanical behavior of the different materials used in the discharges of the plantar pressures of the diabetic foot, in order to choose and use the materials that best suit the objective of the treatment required by the professional. METHODOLOGY The sample of materials used was seven, such as: felts of 3, 4 and 6 mm, poron, lunairmed, lunalastik, eva pelite, lunasoft and high density eva. By means of the compression and dual cantilever tests with the mechanical dynamic analysis machine (DMA), the storage and energy loss behavior was evaluated when the materials are subjected to different frequencies in a certain period of time. RESULTS According to the results obtained, we can say that the Eva family has a higher storage module than the felts. Among them we can highlight that the material that has the highest energy storage module is the high density Eva, followed by Lunasoft, Eva pelite, Lunalastik and Lunairmed.

[gl] INTRODUCIÓN A diabetes mellitus trátase dunha das maiores epidemias do século XXI. Un dos problemas principais que poden padecer este tipo de pacientes denomínase pé diabético, aquelas persoas que o presentan xunto con pérdida de sensibilidade e neuropatía motora, son mais vulnerables a presentar zonas de hiperpresión nos pés, o cal é o principal factor desencadeante das úlceras de pé diabético. Actualmente os podólogos disponen dunha gran variedades de técnicas para facer frente ás presión plantares, entre elas, os soportes plantares, así como multitude de materiais para a confección dos mesmos, cuxo fin, entre outros, consiste en realizar un reparto homoxéneo dás presións que soporta o pé durante a marcha, aliviando así a sintomatoloxía dolorosa. OBXETIVOS O obxetivo deste estudio consiste en coñecer o comportamento viscoelástico e mecánico dos diferentes materiais empregados nas descargas dás presión plantares do pé diabético, co fin de elexir e emplear os materiais que mellor se adecúen ó obxetivo do tratamento requerido polo profesional. METODOLOXIA A mostra de materiais empregados foi de sete, tales como: fieltro de 3, 4 e 6 mm, porón, lunairmed, lunalastik, eva pelite, lunasoft e eva de alta densidade. Mediante os enayos en compresión e dual cantilever coa máquina de análisis dinámico mecánico (DMA) valorouse o comportamento de almacenamento e pérdida de enerxía cando os materiais son sometidos a diferentes frecuencias nun determinado periodo de tempo. RESULTADOS Según os resultados obtidos podemos dicir que a familia das Eva presenta un módulod e almacenamento máis alto que os fieltros. Dentro delas podemos destacar que o material que maior módulo de almacenamento de enerxía presenta é a Eva de alta densidade,, seguida do Lunasoft, Eva pelite, Lunalastik e Lunairmed.
