Abstract

Considering the lack of evidence of the complete role of the scapular dyskinesis (SD) under the conditions of the shoulder and the goal of Principal Component Analysis (PCA ) to reduce the dimensionality of multivariate data while maximizing its variance, this study proposes the application of this method to data of scapulothoracic kinematics, in order to reveal the characteristics of temporal curves of translation and scapular rotation in healthy subjects and subjects with SD and with and without associated shoulder symptoms. The sample will consist of participants of both sexes (n=75), sedentary or irregularly active, aged between 18 and 40 years will be classified into three groups: Group 1 (n=25), control subjects without SD and no symptoms), group 2 (n=25, subjects with SD and no symptoms) and group 3 (n=25, subjects with SD and presence of symptoms). The inclusion will be determined after clinical and observational assessment of SD. Subsequently three-dimensional analysis of the scapula and the scapular sagittal plane with the electromagnetic Liberty ® (Polhemus Inc) system will be performed according to international recommendations. The data will be processed and analyzed through the ACP to determine the main variation in temporal series and the scores of each individual will be analyzed as dependent variables for comparisons between groups. Then, a discriminant analysis will be performed with the scores of each individual in each of principal components. Thus, it is expected to contribute new data to the literature, adding information about the existence of one or more movements of this articulation that distinguishes the groups regarding the variability of movement.
