Item Sistema para el análisis de la marcha humana usando sensores inerciales(Universidad Santiago de Cali, 2019) Saavedra Lozano, Diego Fernando; Castillo Garcia, Javier FerneyThe human gait analysis in specialized laboratories is not available in Colombia for applications such as rehabilitation or sports. Therefore, a capture system is designed using inexpensive inertial sensors to analyze the kinematics of the lower limbs. In this article, initially the characteristics and parameters of the human gait are studied, then it was chosen the inertial sensor that would be used according to its specifications and cost, then the prototype of the inertial capture system was made, and finally, the capture system data was verified by comparing the angle of flexion of the knee with the angle obtained by the artificial vision system from the sagittal plane and comparing it with bands of normality. As a result, it was possible to implement a low-cost inertial motion capture system for the analysis of human gait, with its respective graphical interface to visualize the orientation, flexion and extension angles for each segment and joint of the lower limbs. As a conclusion of this work, it was found that with the information of the artificial vision system, from the sagittal plane, it was possible to identify the gait phases and temporal and spatial parameters such as cadence, step length, stride length, speed of stride, as well as the length of the segments, likewise the inertial system can obtain this information with a system of artificial vision or an anthropometric model, to develop a complete tool for the kinematic analysis of human gait
