Purpose: The aim of the study was to compare the results of six balance tests collected on AMTI AccuSway Plus ACS force platform between healthy female and male children and adolescents. We also searched for possible correlation of the balance measures with subjects’ age. Methods: 228 healthy 6- to 18-year-old subjects (111 boys and 117 girls) participated in the study. Six balance tests were performed with the use of AMTI AccuSway Plus ACS platform: quiet standing for 30s, maximal voluntary sways of the body in the sagittal plane (anterior-posterior – AP test) for 30 s, and in the frontal plane (left-right – ML test) for 30s. All tests were performed in two conditions: eyes open and eyes closed. Results: During quiet standing with eyes open, most balance measures were lower in girls ( p < 0.05). In AP and ML tests with eyes open, a few balance parameters were different between boys and girls ( p < 0.05). In quiet standing, AP and ML tests with eyes closed, there were no between-gender differences ( p > 0.05). In quiet standing with eyes open and closed most balance parameters were negatively correlated with age ( p < 0.05). Conclusions: Quiet standing postural sway characteristics depended on gender under normal visual conditions and it was similar in boys and girls under visual deprivation conditions. The vision was differently used by females and males in balance tasks. Static postural stability improved with age regardless of visual conditions.
