The aim of this study was to acquire static and dynamic foot geometry and loading
in childhood, and to establish data for age groups of a population of 1-13 year
old infants and children.
A total of 10,382 children were recruited and 7788
children (48% males and 52% females) were finally included into the data
analysis. For static foot geometry foot length and foot width were quantified in
a standing position. Dynamic foot geometry and loading were assessed during
walking on a walkway with self selected speed (Novel Emed X, 100Hz, 4
sensors/cm(2)). Contact area (CA), peak pressure (PP), force time integral (FTI)
and the arch index were calculated for the total, fore-, mid- and hindfoot.
Results show that most static and dynamic foot characteristics change
continuously during growth and maturation. Static foot length and width increased
with age from 13.1+/-0.8cm (length) and 5.7+/-0.4cm (width) in the youngest to
24.4+/-1.5cm (length) and 8.9+/-0.6cm (width) in the oldest. A mean walking
velocity of 0.94+/-0.25m/s was observed. Arch-index ranged from 0.32+/-0.04
[a.u.] in the one-year old to 0.21+/-0.13 [a.u.] in the 5-year olds and remains
constant afterwards. This study provides data for static and dynamic foot
characteristics in children based on a cohort of 7788 subjects. Static and
dynamic foot measures change differently during growth and maturation. Dynamic
foot measurements provide additional information about the children's foot
compared to static measures.
