Abstract

The need to deepen the knowledge about the biomechanics of human gait has led to the development of several techniques for analysis and evaluation, in order to ease the diagnosis and optimize the times of eventual rehabilitation. Human gait, as a dynamic process, presents characteristic parameters that allow medical specialists to establish if some patient presents pathologies that affect the biomechanics of gait. The objective of this work was to design and implement a dynamometric platform that allows the calculation and subsequent analysis of the variation of the center of pressures during the march. Four load cells located at the vertices of a rigid square base of 40 cm were used to obtain the reaction force module on the vertical axis, which were registered with a data acquisition system, and processed in an application by Matlab. The tests allowed to verify the displacement of the center of pressures during the march, allowing the analysis of the stability, like a parameter of diagnosis, with a equipment of low cost.
