Trial-by-trial variability of movement dynamics during and after motor adaptation with tDCS

		Block N4	Block F1	Block F4	Block N5
Summed error (m)	Active	1.0 ± 0.1	2.0 ± 0.2*	1.0 ± 0.1	3.1 ± 0.4*
	Sham	1.0 ± 0.1	2.1 ± 0.2*	0.9 ± 0.1	2.4 ± 0.3*
Signed error (m)	Active	0.11 ± 0.01	0.17 ± 0.02*	0.13 ± 0.01*	0.18 ± 0.02*
	Sham	0.11 ± 0.01	0.17 ± 0.01*	0.14 ± 0.01*	0.16 ± 0.01*
Movement time (ms)	Active	76 ± 8	108 ± 9*	83 ± 8	113 ± 8*
	Sham	79 ± 4	112 ± 9*	88 ± 8	107 ± 10*

Values are mean s.d. values ±s.e.m. (n= 14) measured across 24 trials in each block and subject.

^*Significantly different from Block N4 (P < 0.05). There were no significant differences (P > 0.05) between active vs. sham tDCS for any variable in any block.
