In addition, users have new demands about their prostheses and they require absolute comfort and good performance. Unfortunately, the demand of LLP has risen mostly in third world countries because of the increment of vascular diseases (e.g., Diabetes Mellitus) and trauma (vehicle accidents, landmines, etc.). However, people do not have enough funds to acquire advanced prostheses that return the capabilities of walking or jogging in a proper way. Despite the fact that active prostheses help people to reduce metabolic cost, those are heavier and more expensive than Energy Storage and Return(ESR) prosthesis devices, produce uncomfortable noises and require more maintenance than passive ones. Moreover, components of the bionic prosthesis (i.e., actuators, battery, gearbox, among others) make the system highly inefficient. As a consequence, a higher quantity of external energy is required to allow the user to have enough autonomy for daily use. The current work pretends to obtain a novel customizable configuration of the transtibial prosthesis. However, the lack of qualitative and quantitative information on the ankle joint dynamics of LLP users cannot establish a reference target to optimize. In consequence, we processed recent gait data of trans-femoral amputees and compared them with sound groups at different gait speeds. From here, it is reported a formal comparative analysis between those groups. After dynamical data from the gait patterns are obtained, we proposed an explicit dynamic model to emulate the dynamic gait based on the ISO 22675 standard. We proposed a series of design variables in terms of shape, size and laminate thickness for the ankle-foot design. A global sensitivity analysis was performed in order to identify the most influential variables in terms of the outputs established to enhance and, contribute to the validation of the model. Then, a surrogate-model-based optimization algorithm is evaluated to adjust the best design variables for the given input. By means of Bayesian optimization, we found the prosthesis designs with the highest mechanical network for different gait speeds and groups. In the near future, this work will allow customizing, through additive manufacturing, a low-cost ankle-foot prosthesis with the best energetic return at the final stance phase.El avance en el desarrollo de prótesis de miembro inferior se ha acelerado durante la última decada debido a la implementación de dispositivos y materiales óptimos para la función perdida. Así mismo, el estilo de vida de los usuarios de prótesis ha cambiado, por lo que se demanda un mayor confort y rendimiento para una calidad de vida aceptable. Infortunadamente, los sectores más demandados son las poblaciones más vulnerables de los países, que en su mayoría, están en vía de desarrollo. Éstas poblaciones afectadas no cuentan con los recursos necesarios para adquirir una prótesis adecuada al grado de movilidad requerido, lo que produce una reducción en la velocidad preferida para caminar o correr sin alteraciones biomecánicas. Las principales causas de una amputación de miembro inferior se dan por la diabetes mellitus, los traumas (accidentes de tránsito, minas anti-persona, munición sin explotar, etc) y por último, el cáncer. A pesar que las prótesis biónicas ayudan a los usuarios a reducir el costo metabólico extra, estas son más pesadas y costosas en comparación a las prótesis pasivas. Más aún, los componentes de las propulsivas contienen elementos tales como actuadores, baterías, cajas de transmisión, entre otros, que dificultan el mantenimiento a mediano y largo plazo, a parte de generar ruido y hacer el sistema altamente inificiente. Como consecuencia, se afecta la autonomía del usuario en comparación a las de retorno energético. El presente trabajo pretende obtener una metodología de configuración de pie transtibial personalizada. La estrategia para su consecución se basa en la reciclaje de la energía mecánica externa que se pierde en el contacto inicial de la marcha. Sin embargo, la caracterización cualitativa y cuantitativa en la marcha de amputados de miembro inferior es limitada, y por tanto, no existe un parámetro de referencia a optimizar. En consecuencia, se procedió a realizar un análisis de datos con información disponible en estudios revisados por pares de la articulación de tobillo en pacientes con amputación unilateral trans-femoral, y se estableció el valor diferencial de la quasi-rigidéz en comparación con sujetos sin patologías. Posteriormente, se propuso un modelo dinámico explícito de un pie transtibial emulando la dinámica de marcha propuesta en el estándar ISO 22675. En dicho modelo, se establecieron variables de diseño tanto de forma, tamaño y ancho del laminado. Con el fin de determinar el comportamiento de las variables en el entorno y su modelo, un Análisis de Sensibilidad Global se estableció para contribuir a la validación del mismo. El GSA nos permitió implementar un algoritmo de optimización basado en un modelo surrogado cuyo propósito es establecer las variables óptimas de diseño con base en los parámetros de entrada (dinámica de la marcha). Este algoritmo de optimización presenta una cantidad de variables de diseño que no le permiten converger (≥ 20) a una solución óptima. Para solventar este inconveniente,se propone una optimización Bayesiana para determinar las variables de diseño que obtengan la dinámica de tobillo más aproximada a la no patológica. A la cual se obtuvieron resultados muy favorables a lo dispuesto en el mercado de las prótesis pasivas. Con esta propuesta, se pueden configurar prótesis personalizables que, a travéz de la manufactura aditiva, se pueden tangibilizar y adaptar a los pacientes amputados, independientemente de su grado de movilidad y su antropometría.
