Figure 4.

Trunk kinematics in the three spatial planes. From left to the right: sagittal, frontal, and transverse planes, respectively. This figure shows trunk angles at baseline (T0, light gray line) and at T1 (dark gray line) and T2 (black line) follow-up evaluations in a representative patient. Data were normalized to the cycle duration and represented as a percentage of the gait cycle. In the first, second, and third panels, the vertical segments represent the flexion–extension, bending, and rotation RoM, respectively.
