  1. 2 Groups (controls vs. cerebellar) x 2 Sets (single vs. dual task) x 6 Sway Conditions (6 SOT conditions) ANOVA.
  2. p-values < 0.0125 were considered significant (Bonferroni corrected). Modified according to [18].
  3. Double or triple interaction effects between the variables are marked with a *.
