DISPOSITIVO-PLATAFORMA PARA LA MEDICIÓN DE FUERZAS EN BASE AL ANÁLISIS ESTÁTICO DEL MIEMBRO INFERIOR DEL CUERPO HUMANO

The present work has been made as the statics' class project, in which the human´s lower limb was analyzed to determine the strength of the principal muscles involve in the flexo-extension movement of the knee articulation and that way, be able to develop a mechanic device and a virtual platform that could be used as a help by the physiotherapist to get the information of the patient's state through the strength values obtained. Due to the fact that currently there is any mechanism that can perform a quantitative evaluation of the patient´s state by the individual analysis of each muscle. Using the knowledge acquired through the course, different models have been developed to suggest the static equilibrium of the lower limb under previously established initial conditions that set the input data needed to solve the system of equations that followed as a result of the free body diagram. Also, set the designing requirements of the device and to create the algorithm of the virtual platform. Palabras claves. Miembro inferior. Articulación de la rodilla. Movimiento de flexo-extensión.
