The spinal curvature classification in the cross-legged sitting posture

The purpose of this study is to classify the spinal curvature in a cross-legged sitting posture. The sitting position was defined as three positions (flat, lordosis, and slump) considering the spinal curvature. In this study, we developed a classification algorithm that reflects the characteristics of pressure distribution by spinal curvature, and it was able to distinguish three spinal curvatures.
