This work aims to show the importance of the different components that are immersed in lower limb prostheses, either at the Transtibial or Trasnfemoral level. this type of mechanisms substitutes a normal function of the human being as it is the function of the march. With the implementation of this research we intend to help design and build elements that allow us through good practices to generate different levels of well-being for patients with this condition. By having our own and local technologies we can manufacture components at low costs and with a high level of durability; the designs and prototypes are presented in the Center of Design and Metrology - SENA Capital District that has the Orthopedic technology school. Whose specific purpose is to train Technologists in Development and Adaptation of Prostheses and Orthoses.
