Table 1.

P values for the effect of different variables (time, EMG epoch, and task) on muscle response to the perturbation

	Time		Time * EMG Epoch
	Single-cursor task	Double-cursor task	Single-cursor task	Double-cursor task	Cursor Condition * Time * EMG Epoch
Right PM	0.13	<0.001	0.67	0.001	<0.001
Left PM	0.5	0.01	0.71	0.1	0.11
Right Br	0.93	<0.001	0.9	<0.001	<0.001
Left Br	0.56	0.002	0.99	<0.001	<0.001

PM, pectoralis major; Br, brachioradialis. P values are by three-way repeated-measures ANOVA.
