The effect of visual, proprioception and vestibular systems manipulation on postural control in boys with 4-16 years-old

The control ability of body different positions in space was due to interaction between neural, sensory and muscle-skeletal systems, that in generally, defined as a postural control. Thus, the aim of present research was to examine the effect of visual, proprioception and vestibular systems manipulation on postural control in boys with 4-16 years-old. The present research is a crosctional study. The statistical samples included 240 boys with age range of 4-16 years-old (4 age groups) and 60 males were selected. To evaluate postural control, the sensory organization test of computerized dynamic posturography system was used. Collected data were analyzed using one-way ANOVA and post hoc test test. The one-way ANOVA test results showed that the significant differences in postural control groups. Based on the results of Bonferroni post hoc test in condition 1 and 3, boys up to 16 year-old cannot achieve to postural control similar to adults. Also, in condition 2, the results showed that the differences between 13-16 years-old group and adults were not significant, but the differences between other age groups were significant (P<0.05). The 13-16 years-old boys, in condition 4 achieved in postural controls similar to adults. So, there was no significant difference between these groups (P>0.05). In 5 and 6 conditions, boys in all age groups were not able to achieve postural control similar to adults (P<0.05). According to the results of present research, it seems to boys up to 16 years-old could not be process and organization of sensory systems information similar to adults.
