Figure 4 Completion time of grooved pegboard test (GPT) in experiment 2Completion time of GPT recorded at baseline (T0), immediately after the former intervention (T1), and the latter intervention (T2), and 30 min (T3) after the latter intervention in the electroacupuncture (EA)-priming group (red circles) and motor training (MT)-priming group (black squares). Note that in the EA-priming group, the completion time of GPT decreased significantly when the EA was intervened alone (T1 compared with T0) and when it was followed by MT (T2 compared with T0 and T1); furthermore, the completion time of GPT decreased continually at 30 min after the subsequent MT (T3 compared with T0 and T1). In MT-priming group, the completion time of GPT decreased significantly when the MT was intervened alone (T1 compared with T0); whereas, when the EA followed, the completion time of GPT remained unchanged (T2 and T3 compared with T0). Significant difference was observed in T1 between the 2 groups. Values are mean±SD. * Indicates significant differences (P<0.05) compared with baseline (T0); # indicates significant differences (P<0.05) compared with T1; & indicates significant differences (P<0.05) between the 2 groups.
