Diseño e implementación de un sistema inteligente para rehabilitación de rodilla y tobillo basado en una órtesis automatizada

Abstract

This thesis aimed to design and implement an intelligent system for knee and ankle rehabilitation, based on an automated orthosis, to optimize the resources required for their treatment. Using a methodology that consists of a synchronized series of steps, from the approach of the requirements, selection, and configuration of both hardware and software for their integration at the time of implementing the complete system, to its validation, where the design, modeling, and verification of the orthosis was carried out using SolidWorks, taking into account that the orthosis must have the ability to regulate itself to be useful for a wider number of people, using a Raspberry Pi3 as a support with a computer application in Python that manages resources to obtain a high-level interface that allows the registration of user information, calibration of the orthoses, programming of routines for the rehabilitation process, receiving reports and controlling the actuators of the orthoses. It is obtaining an orthosis for knee rehabilitation, adjustable according to the size of a person's leg according to the sample taken 55 cm. The static analysis to validate the parts and materials has given results that show that none of them will suffer fatigue or breakage, and it has also been established that the total displacement, described as "from the initial position to the final position and return to the initial position", is developed in an average time of 327.96426 seconds. It is concluded that an intelligent rehabilitation device has been obtained that can be used with cases of real patients, so it is recommended that the device be evaluated in a medical center with the direct intervention of a specialist and that the rehabilitation process of a patient be followed to determine whether the device contributes to a faster recovery.
