Sagittal trajectories of the hip joint by 3D kinematics gait analysis. Top minus bottom height of the left hip marker, indicating the fluctuation of the hip joint, during walking in SNL rats was 1.47 ± 0.33 cm at 1 weeks post-operation and 1.30 ± 0.25 cm at 4 weeks post-operation. The values of the sham left hind-limbs were 1.47 vs. 1.0 cm and 1.30 vs. 1.0 cm, respectively. OP, operation
