Figure 2 Completion time of the grooved pegboard test (GPT) in experiment 1Completion time of the GPT recorded at baseline (T0), immediately after intervention (T1), 30 min (T2), and 45 min (T3) after the intervention in the electroacupuncture (EA) group and motor training (MT) group. The red circles represent the EA group while the black symbols represent the MT group. The X axis means time points. The Y axis means completion time of GPT (s). Note that completion time of GPT decreased significantly when EA (T2 and T3 compared with T0) and MT (T1, T2 and T3 compared with T0) was intervened alone. Values are mean±SD. * Indicates significant differences (P<0.05) compared with baseline (T0). This figure was produced using GraphPad Prism 10 by GraphPad Software.
