The objective of this article is to determine the accuracy of a new videogrammetry software (CvMob; Federal University of Bahia [UFBA] - Salvador, Bahia, Brazil) in 2-dimensional evaluation of the posture of individuals with Human T cell lymphotropic virus-1-associated myelopathy/tropical spastic paraparesis. A diagnostic accuracy study was used in which survey participants underwent computerized postural analysis through Postural Assessment Software (SAPO; University of São Paulo [USP], Brazil) Software (gold standard) and CvMob. On the final sample with 53 participants, there was a high correlation (r > 0.800, P < .001) between the 2 systems in all angles analyzed. However, receiver operating characteristic curve confirmed that ankle angle evaluation is discrepant between the 2 methods. Angles evaluated by CvMob are accurate for postural diagnosis and are strongly correlated with the absolute values of SAPO, except for the ankle angle.
