Silla Bipedestadora para Personas con Movilidad Restringida Grado Iv en las Extremidades Inferiores con una Capacidad de Carga de 100kg

This article describes the design and construction process of a wheelchair capable of allowing patients with grade IV lower limb disabilities, weighing up to 100 kg, to stand upright. For the sizing of the chair, an anthropometric analysis of 19 adult patients (13 women and 6 men) of the Centro de Rehabilitación Integral Especializado CRIE Nro. 1, located in the parish Conocoto - Quito, Ecuador, was considered, using the P95 percentiles of the anthropometric measurements of the patients of the center. Using Autodesk Force Effect software, the patient's movement was simulated when going from seated to standing, and thus controlling relative positions of lower limbs and trunk, in a range of movement from 15° to 75°, and to have a data base for the selection of the driving system in the chair. By means of a static analysis of loads on the patient's body, the critical design loads were designated for the critical members of the chair, which were verified by means of a stress analysis with Autodesk Inventor V15 software. It also shows the tests and evaluation supervised by 10 physical therapists professionals, through in situ tests with patients of the CRIE N°1 and with a survey to the physical therapists professionals.
