(From 4D Formetric Diers manual with permission). The dimple (D) distance is defined as the spatial distance between dimple left minus dimple right (DL-DR). The dimple middle DM lies on the center of the straight line connecting DL−DR. Trunk imbalance: the trunk imbalance is defined as the lateral deviation of vertebra prominence (VP) from DM in millimeters. Trunk inclination: the trunk inclination refers to an angle formed by the VP−DM line and the vertical in the sagittal plane
