Diseño y construcción de un sistema bio-realimentado, orientado a la adquisición de señales musculares para la rehabilitación de la extremidad superior

Abstract

One of the problems when doing therapy or physical exercises is that user is not conscious about the amount of force that he is developing and in case that the specialist asks for the execution of an exercise at a certain level of force, it is not known for sure that the exercise is done at the desire reference. In these cases, the doctor or trainer must be present during the training to validate, with the expertise that he has gained over the years, that the training is done at the force level required. With this background, this project seeks to implement a bio-feedback system that measures muscular signals generated by the human body and inform the user about the muscular activity that is executing, deploying in a graphical interface information about the level of muscular contraction, the intensity of the contraction, the muscular fatigue analysis and the generation of historical. This work analyses the muscular groups biceps and triceps brachii, measuring, amplifying, filtering, rectifying and integrating the EMG. The tests were performed on eleven subjects, and the sample is composed of people who had muscular maladies while other people were healthy.
