Abstract: Error in measurement of a posture evaluation system is related to the digitalization, camera resolution and distance in relation to the volunteer studied, among others. These errors are summed up during the process and many of them are not possible to be avoided; however, they must be known and quantified. Objective: to quantify the error of the positions measured by SAPO (postural assessment software) in different experimental situations. Methods: 16 photos of a 1.40m tall articulated mannequin were taken at … Show more

“…13 Two articles were found in the current literature correlating such a tool. 18,31 The first merely mentioned it while the second used it as a tool for posture assessment, which indicated that the video system of Biotonix had a high degree of reliability and validity, and that this system is thus suitable for clinical use in posture analysis.…”

“…Segundo Ribeiro 25 , a padronização abrange desde a aplicação dos pontos referenciais para a análise, até o posicionamento do aparelho fotográfico, podendo também relatar a simplicidade do método como ponto positivo para sua aplicabilidade. Além disso, embora a distância da câmera ao avaliado, bem como, a resolução da câmera fotográfica, gerem um erro padrão desprezível, é recomendável que a câmera esteja a uma distância onde o avaliado se encontre no centro da imagem e todo seu corpo seja contemplado 28 . Quanto à resolução, os autores apontam que esta deve ser suficiente para que os pontos anatômicos sejam visualizados no software de imagem posteriormente 28 .…”

“…A digital camera (Sony 6.0MP DSC-T9) was positioned on a level tripod (Vanguard VT-131) parallel to the floor, at a height of 0.90 cm from the ground, with auto-zoom and focal length of 1.80 m for anterior and posterior frontal plane, bilateral sagittal plane 14 ) . Distance between volunteer and the wall was 40 cm, marked on the floor to avoid change of position.…”
