Abstract :The purpose of this study is to investigate healthy people’s and patients’ lower extremity muscle activities during robotic gait using kinesiology analysis. Initially, muscle signals were taken from 6 paraplegic patients such as spinal cord injury insert ignore into journalissuearticles values(SCI); and stroke patients, 2 hemiplegic patients and 4 healthy persons. Then, signals were analyzed by using signal processing techniques such as filtering, rectifying, Root Mean Square insert ignore into journalissuearticles values(RMS); and also by calculating the Max Voluntary Contraction insert ignore into journalissuearticles values(MVC);. As a result, it was seen that hip muscles such as the Gluteus Maximus insert ignore into journalissuearticles values(GMA);, Gluteus Medius insert ignore into journalissuearticles values(GM); and Iliopsoas insert ignore into journalissuearticles values(ILP); had lower MVC values in the hemiplegic patients than those of the SCI patients and the healthy persons. Additionally, when the signals that were obtained were analyzed, it was found that the activity of the Medial Gastrocnemius insert ignore into journalissuearticles values(MG); muscle could be used in determination of movement path and movement intention. Moreover, the EMG results of gait motion may be helpful in applying accurate amplitude and frequency stimulation in epidural stimulation insert ignore into journalissuearticles values(ES); therapy.
