The purpose of this study was to examine the 3-dimensional kinematics of 'normal' walking gait in young children. A cross sectional study using nine children aged between 10 and 24 months, filmed whilst walking at natural speed, was undertaken using two gen-locked video cameras. The children were at different stages of walking development (from 0.5 to 10 months of independent walking (IW)). Repeated measures were taken from two of the children at 10 and 17 months of age and then at 18 and 24 months respectively. 3-dimensional video digitisation techniques utilising the DLT algorithm were used to obtain variables of the gait cycle. The position and movement of the arms were identified as potential motor development patterns. Ranges of movement and motion patterns observed in other variables are useful to determine 'normal' walking gait in such young children. The knees and hips were flexed throughout the gait cycle. Inter-limb asymmetries were observed for the knee angle pattern and for the stance and swing phase time. The mean stance phase time and double support time were 4 and 15% (respectively) greater than in adult's gait. The findings of this study are useful as a guide to research, teaching and clinical professions in this area of biomechanics.
