Abstract

In this study, we developed a robotic gait trainer which induces the gait training based on predefined continuous proper lower extremity joint movements for the paralysis. AC servo motors and linear actuators were used to control hip and knee joints of patients and the weight support system was used to support the patient's weight during the gait training. We also implemented a GUI program to set the gait training pattern with several training parameters and to confirm states of patients and the system through the visual feedback. The effectiveness of the gait trainer will be determined by the long-term clinical experiments in the future. We expect that the developed robotic gait trainer could be applied very practically to recover gait abilities for persons with gait disorder.
