Values are group means ± SE expressed as percentages of baseline tibialis anterior (TA) motor evoked potential (MEP) for the conditioning group of individuals in whom up-conditioning was successful (n = 5) and for the control group (n = 7). C1–6, C7–12, C13–18, and C19–24 are conditioning (or control) sessions 1–6, 7–12, 13–18, and 19–24, respectively.

^*P < 0.05, significant difference from the 6 baseline sessions (Dunnett’s post hoc after one-way repeated-measures ANOVA).
