Evaluation of early walking patterns from plantar pressure distribution measurements. First year results of 42 children.

This study evaluated developmental changes of foot and gait during the first year of independent walking. In a longitudinal design, plantar pressure distribution patterns were measured with a capacitive platform every 3 months in a group of 42 normal children. The first significant changes were already found after a few weeks of independent walking. The development of the longitudinal arch correlated with significantly reduced midfoot loading parameters even though the changes showed a wide interindividual variation. This study illustrates that a child's foot goes through significant changes in shape and loading characteristics once the child starts to stand and walk. Some children showed a fairly mature appearance of the plantar pressure pattern after 1 year while others retained a more immature loading pattern.
