Background & Objectives: The lower limb bears the weight of the body and its disorder can affect the postural control. This study aimed to investigate the effect of cognitive dual task on postural control of children with flat feet and genu varum.
Methods: The current study employed a semi-experimental approach featuring a pre-test and post-test design. The study focused on elementary school students in Bandar Anzali city, specifically 88 individuals aged between seven and 12 years. These participants were selected through cluster sampling from six elementary schools and were purposefully divided into three groups: individuals with flat feet, individuals with genu varum, and healthy individuals. The pre-test phase involved each participant standing on the Static Stabilometer for 15 seconds, during which the displacement of their center of pressure was meticulously recorded. In the subsequent post-test, a random cognitive dual task was introduced, involving reverse counting of numbers. This task was designed with two stages, each with varying difficulty levels tailored to the children's abilities. Data analysis was done using SPSS software version 28 at a significance level of p<0.05.
Results: Effect of the cognitive dual task on anteroposterior sway index (p=0.003), mediolateral sway index (p=0.028), and overall sway index (p=0.003) is significant; but the cognitive task did not show a significant effect on the sway speed (p=0.353). The obtained results show that the group effect and the interaction effect of the group and the cognitive task were not significant on any of the postural control indicators (p < 0.05).
Conclusion: When individuals with flat feet, genu varum, and healthy participants simultaneously performed the cognitive task, it was expected that the displacement of their center of pressure would increase compared to when they executed the task individually. However, this increase in displacement did not show a significant difference among the three groups. Consequently, it can be inferred that maintaining balance in all three groups is not an automatic process and demands attention.
