- Abstract
The computerized photogrammetry has been highlighted as a non-invasive resource for evaluation, with good reproducibility of results, but its application parameters are still lacking standardization. This study compared outcomes of range of motion obtained with photogrammetric assessments from images photographed in different camera inclinations in relation to the object (0°, 5°, 10°, 15°, 20°, 25°, and 30°). The images were analyzed with computerized photogrammetry by six raters who assessed the joint range present in the images. The outcomes showed that even with 5° in camera inclination, there was significantly different results between assessments, and the margin of error increased as the camera inclination was intensifying.
