Abstract

Human postural control acquired by a force plate is an object of study in different Healthcare areas. However, researchers without much experience in other areas of knowledge, such as Statistics and Information Technology, observe their data only quantitatively. Therefore, as complement to these biomechanical analyses, this paper aims to compare, retrieve and visualize similar behaviors of the Centre of Pressure (COP) measured according to static positions performed by elderly people with sarcopenia, before and after the application of a muscular training intervention. For this purpose, the medial-lateral (ML) and anterior-posterior (AP) directions of the COP's oscillations are used, respectively, as coordinates on the x- and y-axes, to which the Fourier Transform is applied to extract features from each set of coordinates that will represent each data collection during comparisons by the Euclidean distance metric. The acquisitions are ranked based on the similarity they share with the one defined as query. As a result, only acquisitions of interest are retrieved. Case studies involved comparisons of pre- and post-intervention data collections from 4 subjects performing different static positions on the force plate. Scatter plot visualizations, combined with comparisons and retrievals of similar behaviors among COP’s oscillations, facilitate analyses and insights regarding the subjects' postural balance performance during force plate data collections.
