Values are presented as mean ± standard deviation. SO, static under eyes-opened condition; SC, static under eyes-closed condition; DO, dynamic under eyes-opened condition; DC, dynamic under eyes-closed condition; OSI, overall stability index; APSI, anterior-posterior stability index; MLSI, medial-lateral stability index. *Significant at p < 0.05.
