Kinesiological characteristics of ankle joint and rearfoot motion.

Kinesiological analysis of tarsal bones provides better understanding of foot disorders, especially in early childhood, when radiography is hindered by delayed ossification of foot bones. Children begin to walk in the age of 9-15 months, with rearfoot inversion only in initial contact phase, while inversion during terminal stance phase is delayed. Adult walking pattern is usually established at six years of age.
