Abstrakt		FES assisted gait of paraplegic patients is inferior compared to a healthy subject. The difference can be observed in terms of speed, up-right balance, biomechanical energy consumption and generation of propulsion forces in the direction of walking. The biomechanical structure is the same as in normal, however the mode of walking differs significantly because of reduced number of activated muscles and primitive control. The healthy subject is utilizing two-point dynamically stable gait. The paraplegic patient is employing 4-channels of FES and utilizing a four-point statically stable gait. We believe that FES gait can be improved if converted into a semi-dynamically or dynamically stable gait. The gait is considered statically stable if the center of gravity (COG) projection on the ground (PCOG) is inside the supporting area. In quadruped this is only possible if it is utilizing creeping crawl gait. In this paper the relationship between PCOG and the supporting area are discussed as a criterion for dynamic stability assessment. Results are shown for three different modes of two-point and four-point gaits.
