Sistema háptico de telemedicina para la detección de niveles de artritis en manos aplicando métodos no invasivos

Abstract

This research project deals with the development of a non-invasive electronic prototype for measuring the flexibility of the fingers of the hands, through the investigation of the vital signs that intervene in the movement of the fingers and establishing the strategic points of reference for the movement of the hands, thus generating flexibility values so that the specialist doctor can generate a quick diagnosis of the level of arthritis. Currently, the procedures for detecting arthritis in the hands are carried out using Xrays or invasive tests that make patients uncomfortable due to the pain they suffer. The main objective was the realization of a prototype that is based on a haptic glove, which allows to measure the flexibility of the movements required for a medical evaluation, this system uses flex technology and processing and transmission modules, the same ones that are programmed in Depending on the movements of each of the fingers of the hand, the system is preconfigured by declaring the healthy parameters of the hand in its natural state without muscle and joint atrophy, which are used for the comparison and detection of the level of arthritis that the patient has. The development of the system was based on the use of free hardware and software, programmed in Arduino IDE, the values were acquired based on the flexibility of the sensor, these values were normalized and displayed so that the doctor generates a quick and accurate diagnosis. Finally, the haptic system is made up of the sensor glove, which consists of flexibility sensors for data acquisition according to the movements made with the hand, having an effectiveness of 97% in the measurement values and 98% in the diagnosis of patients.
