The main purpose of this study is to investigate the changes in the signs of flatfoot of preschool-aged children in a 1-year follow-up study. This study performed follow-up on a total of 580 preschool-aged children (boys, 297 children; girls, 283 children) with a median age of 54 (range 36-71 months), and the average follow-up period was 11.8 months. This study used the Chippaux-Smirak index (CSI) of footprint as the assessment tool, and CSI > 62.70 % was used as the standard for determining whether preschool-aged children suffered from flatfoot. The results showed that the signs of flatfoot of preschool-aged children improved with increasing age. At the 1-year follow-up, the average CSI was 5.1 % lower, and the proportion of children with flatfoot was 14 % lower. The follow-up on the change in the signs of flatfoot showed that 37.6 % of the children originally with flatfoot had improved to normal, verifying that flatfoot indeed improves with increasing age. However, the results also showed that 9.9 % of the children who originally had normal feet had developed flatfoot with increasing age, which deserves subsequent investigation. The results of the follow-up also showed that children who were relatively younger, male, obese, and experiencing excessive joint laxity were more likely to experience the signs of flatfoot. Conclusion: The 1-year follow-up found that some preschool-aged children with flatfoot may develop normal feet, while children with normal feet may begin to experience the signs. Relevant factors affecting flatfoot in preschool-aged children continue to require further clarification.
