In this work, a new technique for symmetry line detection for non – erected postures is presented. The proposed approach, based on a symmetry index previously defined by the authors, is adapted to analyse non – erected postures which can not be investigated with the other methods presented in the literature. The method here proposed is validated by analysing four different non – erected postures in which the spine does not ideally lie onto sagittal plane: twisted posture (left, right) and laterally flexed posture (left, right). The proposed approach evaluates the symmetry line by means an adaptive process in which a first attempt is modified step by step until the solution converges to the best estimation. The method is compared with the traditional approach to symmetry line detection having as reference the cutaneous marking. Results are analysed and critically discussed.

Abstract
In this work, a new technique for symmetry line detection for non – erected postures is presented. The proposed approach, based on a symmetry index previously defined by the authors, is adapted to analyse non – erected postures which can not be investigated with the other methods presented in the literature. The method here proposed is validated by analysing four different non – erected postures in which the spine does not ideally lie onto sagittal plane: twisted posture (left, right) and laterally flexed posture (left, right). The proposed approach evaluates the symmetry line by means an adaptive process in which a first attempt is modified step by step until the solution converges to the best estimation. The method is compared with the traditional approach to symmetry line detection having as reference the cutaneous marking. Results are analysed and critically discussed.Pubblicazioni consigliate
