Accuracy and reliability of a low-cost methodology to assess 3D body posture based on commercial cameras and Excel templates

Analysing posture in 3D generally requires expensive equipment and complex software, not accessible to most healthcare centres. The aim was evaluate a postural analysis methodology based on commercial cameras, portable calibration device Excel, popular spreadsheet software. accuracy reliability of the were studied using optical motion capture system with submillimetre as reference. 99 length angular anthropometrics parameters 9 subjects measured Lin’s concordance correlation coefficient (Lin’s CCC), magnitudes errors Bland Altman graphs computed. measurement approximately 2 mm 1–2 deg, reliable CCCs above 0.99). suggested low-cost could be used for applied studies, analysing asymmetries, alterations or population-based anthropometric parameters, where usually is required therefore can useful medical centres limited budget.
