	F Value	C1–6	C7–12	C13–18	C19–24
Conditioning group without SCI
Conditioned SP	F(4,16) = 3.7	96.4 ± 3.8	91.1 ± 8.7	85.7 ± 8.4	80.1 ± 7.6*
Control SP	F(4,16) = 2.4	96.0 ± 3.4	97.5 ± 5.6	92.2 ± 6.4	87.8 ± 4.1
Within-session change	F(4,16) = 1.0	0.4 ± 5.3	−6.3 ± 7.0	−6.5 ± 7.2	−7.7 ± 8.5
Control group without SCI
Conditioned SP	F(4,24) = 0.9	97.6 ± 3.0	98.8 ± 4.0	99.8 ± 3.9	95.1 ± 2.5

Control SP	F(4,24) = 2.1	96.3 ± 3.4	94.3 ± 5.3	91.2 ± 7.1	88.2 ± 6.8

Values are group means ± SE expressed as percentages of baseline silent period (SP) duration for the conditioning group of individuals without neurological conditions in whom up-conditioning was successful (n = 5), for the control group of individuals without neurological conditions (n = 7), and for the conditioning group of individuals with SCI in whom the SP could be evaluated (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 differences from the 6 baseline sessions (Dunnett’s post hoc after one-way repeated-measures ANOVA).
