Аннотация
BACKGROUND: The use of statistical parameter mapping (SPM) to compare gait kinematics of children at different ages seems to be a more appropriate tool to describe the differences than simply describing the maxima and minima on the curves.
RESEARCH QUESTION: Does lower limb kinematic waveforms differ during gait in normally developing preschool children?
METHODS: In a cross-sectional study, SPM was used to compare kinematic waveforms of typically developing preschool children at ages 2, 3, and 6 years (n = 42).
RESULTS: Differences in internal rotation foot angle between 2-year-olds and 3-, 6-year-olds in 22-55 % lower in 2-year-olds but 85-100 % greater in 2-year-olds. Greater internal rotation of the knee in 2-year-olds versus 6-year-olds in 13-25 % of the stance phase. Lower knee abduction in 2-year-olds versus 6-year-olds in the first 13 % of the stance phase.
SIGNIFICANCE: Comparison of the waveforms of the angle may provide a clearer understanding of the differences in gait kinematics in children at different ages.
