Scores on the Oswestry Disability Index (ODI), Japanese Orthopedic Association Back Pain Evaluation questionnaire (JOABPEQ), and Numerical Rating Scale (NRS) were significantly improved at follow-up. (D–G) Gait analysis. Walking speed, stride length, sagittal tilt, and frontal tilt all improved, but none of these parameters reached the level found in healthy subjects. *p < 0.05. n.s. not significant.
