title: A 3-D skeleton model & SEMG approach for integrated neck and low back pain analysis test batteries.
abstract: Since several years our group is working on a project to merge into a full 3D reliable and detailed human skeleton representation various segmental biomechanical models presented in literature. The obtained 3D skeleton model is fully parametric and can be fitted to each subject anthropometric characteristics. A non-ionising approach based on 3D opto-electronic measurements of body landmarks labelled by passive markers has been chosen to build the 3D parametric biomechanical skeleton model. A special focus has been devoted to identify and model the spine with a correct degree of accuracy and reliability. In spine pain related pathologies is of major importance the evaluation of functional limitations associated. This requires to integrate morphological characteristics with information deriving from other measurements devices as force platform data, surface EMG, foot pressure maps. The aim of this study is to present a multi-factorial approach which integrates rachis morphological characteristics with full skeleton kinematic, dynamic and SEMG measurements to quantify spine function and mobility in particular for neck and low back pain. A set of clinical-biomechanical tests have been implemented. Static posture characteristics are first evaluated. After that, patient is asked to perform specific motion test batteries in order to fully measure the whole ROMs (spine angles ranges and spine shape modifications) for Axial rotations, forward-backward flexion-extension, lateral bendings per each spine functional units (Skull and neck, thoracic and lumbar districts). During forward bending also a digital Schober test is performed. Such data are correlated to simultaneous SEMG muscle activities recording to investigate motor co-ordination/dysfunction as well as the presence absence of flexion-relaxation phenomena associated to pain.
