Studies in the past have shown the ability of systems to track adult foot and ankle motion. However, a more complete understanding of the complexities of the pediatric foot and ankle motion has yet to be obtained. The objective of this study was to develop and characterize an active marker based system capable of tracking three dimensional (3-D) motion of the pediatric foot and ankle during both the stance and swing phases of gait. Clinical validation of this system was demonstrated by collecting data from a three segment rigid body model of the pediatric foot and ankle that described the motion of the tibia, hindfoot and forefoot. Data from five normal subjects and five subjects with cerebral palsy, between the ages of 5-16 years, has been presented.
