The studies of human locomotion have been well documented and analyzed by many investigators. However, most of them deal with the normal and pathological gaits of the adult and there has been very little literature pertaining comprehensive analysis of infant locomotion from a biomechanical aspect. This report concerns with the level walking of the infant of 3 and 4 years of age as compared with that of the juvenile and the adult. The experimental method for simultaneous recording of the kinematic and dynamic data consisted of cinematography and force platform having a three-dimensional force-transducer. Using the data obtained from these methods, the simulation was carried out by a two-dimensional mathematical model. Thus joint moments, joint reactions, muscular forces, transmitted forces at joints and generated power were estimated. It was clarified that while some variables were identical to adult values, the propulsive mechanism as well as the angle, moment and transmitted force at the knee joint and the generated power in the infant was different from those of the adult. The comparison with non-human primate bipedal walking indicates that the locomotion of the infant may be placed between the human type and the non-human primate type, although it is much nearer to the human type.
