Estudio y análisis de la fiabilidad de señales biofísicas (fotogrametría y electromiografía) del miembro inferior en una determinada actividad física.

Abstract

The human being is in constant movement, from the daily walk, work activities and high-performance activities in sports. These activities involve the activation of muscles and the specific coordination of skeletal mechanisms to generate specific movements. In many of the activities mentioned, a correct technique is not used, even for walking, leading to complications in the future. Studying biomechanics in the strength form of it and based on normalization techniques will help to establish functional movement characteristics and physiological capacity through the implementation of functional movement patterns.

Functional patterns are obtained by comparing theoretical and experimental data. Experimental data is obtained using the techniques of photogrammetry and electromyography. In order for the experimental data to be validated, connection relationships are determined. For photogrammetry, the correlation is determined by analyzing theoretical data from a double pendulum model and from an OpenSim model. OpenSim is a free software that allows to analyze, build, and exchange dynamic movement simulations and musculoskeletal models. To determine correlations in electromyography, data from “The Gran Challenge Competition to Predict in Vivo Knee Loads”, a competition conducted by ASME, is analyzed. In this way it is possible to determinate the functional patterns of the movement of the lower limb in a certain physical activity. The established methodology is reproducible for different movements with the photogrammetry technique and for certain muscles with the electromyography technique.
