Single-pulse TMS in surrounding muscle APB for all four phases of the movement and the two conditions

	EF				IF

MEP size (mV)	1.22 ± 0.89	0.63 ± 0.71a,b,c	0.88 ± 0.55a,b,e	1.44 ± 1.03a,c,d	1.17 ± 0.96	0.87 ± 0.86a,b,d,f,g	1.02 ± 0.73a,b,g	1.42 ± 1.02a,f

Shown are mean values and SD (n = 12) for single-pulse MEP size, MEP size related to control MEP expressed in percent and the background EMG (bEMG) for both conditions (EF and IF) in the surrounding muscle APB. Main effect of phase: significant difference (P < 0.05) for this phase in both conditions compared with the control phase (a) and compared with the tonic phase (b). Interaction effect focus x phase: significant difference (P < 0.05) for this phase compared to control (c), premotor (d), tonic phase (e) in the EF condition and compared to control (f) and tonic phase (g) in the IF condition. EF = external focus, IF = internal focus of attention.
