  • Data are presented as the session 1 baseline value (mean and SD), the mean session difference (with 95% CI), the SEM and the MDC. For the Good Balance test negative values denote an improvement from session 1 to session 2, while for the Star Excursion Balance Test positive values represent an improved test score.

  • AP, anterior–posterior; MDC, minimal detectable change; ML, mediolateral; SEM, SE of measurement.
