Mean pretest and posttest performance for each group in experiment I. Error bars represent SE. Subjects improved on both trained tasks [stability platform: P < 0.001 (A); simulated feeding: P < 0.001 (B)] from pretest to posttest but training did not generalize to the untrained single leg stance task [P = 0.802 (C)]. Subjects who received DCS did not demonstrate enhanced performance on any task compared with participants who were given placebo (stability platform: P = 0.555; simulated feeding: P = 0.196; single leg stance: P = 0.864).
