For the purpose of establishing the optimal therapeutic programs for spinal diseases, the authors evaluated the gait disturbance of the patients measuring ground reaction force (GRF). 94 cases of representative spinal diseases were studied GRF evaluation indices as well as clinical evaluation score (JOA score) before and after therapeutic interventions. The gait analysis based on GRF provided accurate, objective, quantitative evaluation of the intervention effects, that was considered a

Pre-and postoperative GRF findings of 3 repesentative spinal cases are presented.
