The purpose of this study was to compare pedaling patterns according to pedal types during driving. Three-dimensional gait analyses were performed from a self-selected pace, and fourteen subjects participated in the three times(the early, middle and last years). Six cameras (Proreflex MCU-240, Qualisys) were used to acquire raw data. The parameters were calculated and analyzed with Visual-3D. In conclusion, most joint - ROM of lower limbs were less than two-foot pedal system. It is necessary that the current pedal system is to be improved.
