RESUMO

This study aimed to verify the reliability of the postural evaluation method using the Postural Assessment Software SAPO. This software consists of an assessment program with digital photographs, through computerized photogrammetry. Twenty students with 8.3 ± 0.8 years of age were photographed on the anterior, left and right laterals and posterior views. The points usually used for postural assessment, proposed by the SAPO protocol, were marked on the subjects skin. Through these points, the analysis from different angles was done by the Postural Assessment Software SAPO. The intraexaminer analysis was done by one single examiner, who evaluated the same photos twice, in a one-month interval. The interexaminer analysis was done by three different professionals, who evaluated the photographs and had their results compared. The method used for intra- and inter-examiner comparison of results was the intraclass correlation coefficient. Results showed that SAPO can be considered a reliable tool to assess students posture, as in both intra- and inter-examiners analysis most angles were reliable. Among the statistically reliable angles, some had low level of reliability, mostly in the lateral view, regarding the alignment of the pelvis, head, ankle and hips, and in the posterior view, the leg and hindfoot angles. Thus, it is suggested the Postural Assessment Software SAPO is a reliable method for postural assessment. Nevertheless, further studies are needed in order to better verify its reliability in lateral and posterior views, especially in angles involving sagittal plan spinal curvatures.
