Postural control assessments included Center of Pressure (COP) range and COP velocity in the Anteroposterior (AP) and Mediolateral (ML) directions, and the COP sway area in the standing position with opened eyes and closed eyes by the force plate.<br><strong>Results: </strong>This study showed that the postural control variables in AIS adolescents and healthy adolescents in terms of COP range, COP velocity, and COP sway area in standing positions with open and closed eyes were significantly different with those of AIS adolescents being worse than those of healthy adolescents (all p<0.001). The interaction between Group and Condition (eyes open and eyes closed) was not significant for all variables (all p>0.05).<br><strong>Conclusion:</strong> Differences in the postural control measures indicate postural instability in adolescents with AIS compared to healthy adolescents.<br><br> https://www.jimc.ir/article_172546_6cd6971b4d3faec9719e5c0109f3f929.pdf
