The system for estimating the posture and movement of the spine, SpineMeasure, is patented, and consists of a set of inertial sensors that are placed at different points in the thoracic and lumbar regions of the spine, and a personalized computational mechanical model of these regions of the spine. The orientation measurements of the sensors are collected by the software that implements the model, and which provides the estimation of the orientation of the vertebrae in real time according to the format preferred by the user (see reference [18] in the Publications section). In the image, you can see the sensors placed along the subject's spine, as well as the box that is connected by a cable to each sensor, and which contains the components necessary for its operation.
