Background and Objective: The ability to control various body positions in space caused by a complex interaction of, sensory, musculoskeletal and neural systems, that is generally defined as a postural control system. Thus, the purpose of present study was to examine the effect of sensory systems manipulation on postural control in boys with 4-15 years-old.
Materials and Methods: The statistical sample included 160 boys with age range of 4-14 years-old (in 4 age groups) and 40 male with age range of 22-25 years-old that selected based on inclusion and exclusion criteria. To evaluation of postural control, the sensory organization test of computerized dynamic posturography system was used. This test is composed of 6 conditions and can be assessed the sensory systems that involved in postural control. Also, weight, height and BMI of subjects were measured.
Results: The one-way ANOVA test results showed that there are significant differences in postural control among all groups. Based on the results of Bonferroni post hoc test in condition 1, boys up to 15 year-old cannot achieved to postural control similar to adults. Also, in condition 2, results showed that the differences between 13-15 year-old group and adults were not significant, but the differences between other age groups were significant (P < 0.05). Furthermore, in condition 3 the results were obtained similar to condition 1. The 13-15 years-old boys, in condition 4, achieved in postural control similar to adults, so that there were no significant difference between this groups (P>0.05). In 5 and 6 conditions, Subjects in all age groups were not able to achieved postural control similar to adults (P < 0.05).
Conclusion: According to the results of present research, seems to boys up to 15 years-old could not be process, integration and organization of sensory systems information similar to adults.
