“…The optical filters selectively transmit light in a particular range of wavelengths -from 600 nm to 700 nm -while blocking the remainder. Therefore the fluorescent marks stand out in the pictures acquired by the cameras which allowed the definition of less demanding image processing algorithms (Gabriel, 2015b).…”

“…The algorithms will identify the fluorescent marks and determine its tridimensional coordinates. It is noteworthy that data acquisition is completed in such a short period of time -between 30 and 40 secondsbecause image processing is performed after a complete full scan of the spine (Gabriel et al, 2015b).…”

“…Vertebral Metrics -National patent PT/103990, European patent PCT/IB2009/005018 and American patent US20110004125 -is a non-invasive system designed to identify the spatial position of the spinal apophysis from the first cervical to the first sacral vertebrae in the standing position. Using a fluorescent marker to identify the skin projection above the spinal processes, recognition is achieved with software capable of distinguish the marks (Gabriel et al, 2015a;Gabriel et al, 2015b). Due to its versatility the equipment can have several applications from screening and prevention to monitoring the intervention methodologies for each clinical case.…”

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.

“…It is a patented device (patents PT/103990, PCT/IB2009/005018, and US20110004125) that was designed to identify the spinous processes' apex position without ionising radiation [28]. As such, it combines a stereo vision system with software that recognises fluorescent marks in the skin [29,30]. The device was developed, and the measurement resolution was determined [30].…”

Back pain is regularly associated with biomechanical changes in the spine. The traditional methods to assess spine biomechanics use ionising radiation. Vertebral Metrics (VM) is a non-invasive instrument developed by the authors in previous research that assesses the spinous processes’ position. However, the spine model used by VM is not accurate. To overcome it, the present paper proposes a pioneering and simple articulated model of the spine built through the data collected by VM. The model is based on the spring–mass system and uses the Levenberg–Marquardt algorithm to find the arrangement of vertebral bodies. It represents the spine as rigid geometric transformations from one vertebra to the other when the extremity vertebrae are stationary. The validation process used the Bland–Altman method to compare the Cobb and the intervertebral angles computed by the model with the radiographic exams of eight patients diagnosed with Ankylosing Spondylitis. The results suggest that the model is valid; however, previous clinical information would improve outcomes by customising the lower and upper vertebrae positions, since the study revealed that the C6 rotation slightly influences the computed angles. Applying VM with the new model could make a difference in preventing, monitoring, and early diagnosing spinal disorders.
