Balance training reduced the number of errors during one-legged stance. Mean number of errors committed during 15 s of one-legged stance on stable ground (a; Static task) and on a free-swinging platform (b; Dynamic task) before (Pre) and after (Post) five weeks of balance training (Training group, filled circles) or habitual activity (Control group, open circles). In (c) and (d), the change from pre to post is displayed for the static and the dynamic task, respectively. An error was defined as touching the ground with the foot of the non-supporting leg or holding on to a handrail. For each participant, the mean of three trials was used. *The change from pre to post differed significantly between groups (p < .05). n = 15 for the training group, n = 13 for the control group for (a) and (c); n = 12 for the training group, n = 13 for the control group for (b) and (d). Error bars represent the standard error of the mean
