Comparison Balance and Footprint Parameters in Normal and Overweight Children

BACKGROUND: The present study was done in order to compare balance and footprint parameters in two groups of normal and overweight children. METHODS: This semi-experimental study included randomly selected 22 male children (11 normal and 11 overweight boys). To measure the footprint parameters, an ink paper system was used, i.e., after putting their feet in the ink, the subjects were asked to stand comfortably on paper and their footprints were recorded. Then, with the use of ImageJ software, the areas of anterior, middle, and posterior parts, the total area, and the arch index parameter were calculated. For measuring balance in three posterolateral, posteromedial, and anterior directions as well as the total balance, Y-balance test was done. Finally, to analyze the data, mean and standard deviation were calculated and ANOVA test was used to compare the parameters. RESULTS: Data analysis showed a significant difference between normal and overweight subjects in the anterior and posterior areas, whereas, in balance test, only the anterior areas showed significant difference (P < 0.05). CONCLUSIONS: It seems that area parameters in these two groups do not have significant difference; hence, it cannot be used as the criteria for analyzing the effects of being overweight on these parameters. In addition, it is probable that, in a dynamic situation, recorded footprints are more valid parameters for analyzing foot structure.
