  1. Legends: Difference values from period 1 - period 2. P-values were computed using Wilcoxon signed rank test for group 1 and group 2 at period 1 and period 2.
  2. ES: effect size, AP: anterior-posterior, ML: medial-lateral, FRT: Functional Reach Test, ETGUG: Expanded Timed Get Up-and-Go, ST: single task, DT: dual task, RTH: reaction time hand, RTF: reaction time foot, mm: millimetre, s: seconds, m/s: metre/seconds, ms: milliseconds, ss: sit-to-stand, m: metre.
