Analysis of centre of pressure in standing position in young subjects with Down syndrome

"The two purposes of the study were to analyze Centre of Pressure (COP) behavior in a standing position in a group of young adults with Down Syndrome (DS) in different visual conditions, and to compare the results with a control group (CG). All participants were a part of a dance training program. There were 11 young adults with DS, six females and five males, aged 20.5 (1.3) and 12 non DS adults, eight females and four males, aged 20.3 (2.0). All participants were previously studied related to an anamnesis and physical exam. Bipedal standing position was evaluated in closed eyes and open eyes conditions for 30 seconds. Data were collected relative to COP from the platform (AMTI-SGA6-4): sway area, anteroposterior and mediolateral displacement, and also maximum displacement excursion. Differences in all parameters were compared between both groups using Mann-Whitney U test. Wilcoxon test was applied to compare differences between open and closed eyes in both groups. Significant differences were found (p
