Figure 3. Video-based kinematic analysis revealed reduce hip
extension in the ipsilateral limb
The whole-body skeleton was visualized during level walking using the
OpenPose system. Graphic illustrations represent the terminal stance
phase of the ipsilateral (left panel) and contralateral (right panel)
limbs. Terminal stance in the ipsilateral limb is characterized by
reduced hip extension, indicated by a lower hip extension angle (angle
between the femur and the vertical line) manually measured by Image J
software. The values of the hip joint angle are provided based on a
camera coordinate system.
