Initial position and kinematic quantification. Left panel: Subjects began the movement from a standardized initial position with marker placements as shown. Middle panel: Trunk angle was calculated as the sagittal plane angle between C7 and the sacrum, relative to vertical. Right panel. The total sagittal thoracic angle (θthoracic) was obtained by adding the individual joint angles at T4, T7 and T10 computed between adjacent markers. Similarly, θlumbar was obtained by summing L1 and L4 joint angles.
