Vertebral metrics application of a non-invasive system to analyse vertebrae position using two seating platforms

The study of the biomechanical changes in the spinal column is particularly important in modern society since they are considered the main responsible for back pain. Vertebral Metrics is an instrument that aims the global evaluation of the spinal column. Noninvasively and semi-automatically, this image processing based system allows the identification of X, Y and Z position of each spinal process on standing position. The analysis of vertebraes position using two different seating platforms through the application of Vertebral Metrics is the aim of this work. Along the paper the main stages concerning to the study will be described. Nine volunteers were recruited and an ergonomic chair and a bench were used to perform the study. Results show that differences in vertebrae position are not relevant when sitting in the ergonomic sit or in the lab. Also, spinal curvatures as well as lateral deviations of the spine were properly represented from data collected with Vertebral Metrics. The study proved that Vertebral Metrics has a huge potential to perform the analysis of the spinal curvatures.
