“…Moreover, it is desirable to obtain adequate spine motion measurements while keeping a small set of surface markers. Some literature proposal modelled the spine in various rigid segments (including multiple vertebrae) identified by clusters of markers [39][40][41] (see Needham et al, 2016 for a review [47]). In others, the vertebral column was modelled by linear segments joining markers placed one every two spinous processes [31][32][33].…”

“…Indeed, various solutions have been developed for the modelling of the vertebral column. The first line of research focused on representing the spine in various rigid segments (including multiple vertebrae) identified by clusters of markers [39][40][41] (see Needham et al, 2016 for a review [47]). Another approach was to model the column by linear segments joining the markers placed on spinous processes (usually one out of two) [31][32][33].…”

Quantitative functional assessment of Posture and Motion Analysis of the entire skeleton and spine is highly desirable. Nonetheless, in most studies focused on posture and movement biomechanics, the spine is only grossly depicted because of its required level of complexity. Approaches integrating pressure measurement devices with stereophotogrammetric systems have been presented in the literature, but spine biomechanics studies have rarely been linked to baropodometry. A new multi-sensor system called GOALS-E.G.G. (Global Opto-electronic Approach for Locomotion and Spine-Expert Gait Guru), integrating a fully genlock-synched baropodometric treadmill with a stereophotogrammetric device, is introduced to overcome the above-described limitations. The GOALS-EGG extends the features of a complete 3D parametric biomechanical skeleton model, developed in an original way for static 3D posture analysis, to kinematic and kinetic analysis of movement, gait and run. By integrating baropodometric data, the model allows the estimation of lower limb net-joint forces, torques and muscle power. Net forces and torques are also assessed at intervertebral levels. All the elaborations are completely automatised up to the mean behaviour extraction for both posture and cyclic-repetitive tasks, allowing the clinician/researcher to perform, per each patient, multiple postural/movement tests and compare them in a unified statistically reliable framework.
