The purpose of this study was to investigate the gait pattern effects on gait exercises using the walking assist device ACSIVE. Experiments 1 and 2 were both intended for twenty healthy subjects. Experiment 1 compared the effects on the gait pattern between barefoot walking and walking with ACSIVE. In Experiment 2, the purpose was to compare the effects on the gait pattern between barefoot walking and walking with ACSIVE after gait exercises. Their walking was measured using an optoelectronic motion capture system with ten infrared cameras (VICON612) and a ground reaction force platform (AMTI : OR6-6). Kinetics data were calculated using the inverse-dynamics method. As a result, assist by ACSIVE affected the terminal stance from the loading response phase of the hip and knee joints. Further, after the walking exercises with ACSIVE, in hip moment, the maximum extension moment of loading response phase and mid-stance was increased, which reduced the maximum flexion moment.
